OPINION
SUZUKAWA, J.
INTRODUCTION
From the mid-1980's until 1993, defendant and respondent The Pampered Chef, Ltd., purchased a kitchen device known as the Tartmaster from plaintiff and appellant Kitchen Connection, Inc. In about 1993, Pampered Chef learned that the patents on the Tartmaster's design had expired, and it began sourcing copies of the Tartmaster (which it called the Cut-N-Seal) from defendants and respondents Good Things International, Ltd. and Ten Mark Corporation. Kitchen Connection discovered no later than mid-1993 that Pampered Chef was sourcing Tartmaster copies, but it waited nearly 10 years, until 2003, to file the present suit for trade dress infringement, unfair competition, and false advertising.

Plaintiffs' trade dress claims were presented to a jury. After both sides presented their evidence, the trial court granted a directed verdict for defendants, concluding that the claims were barred by laches and the statute of limitations as a matter of law. Then, sitting without a jury, the court further found for defendants on the unfair competition and false advertising claims. Subsequently, it denied defendants' motions for attorney fees.

Plaintiffs appeal the judgment for defendants, and defendants Good Things and Ten Mark appeal the denial of their motions for attorney fees. We find no error, and we affirm.
FACTS AND PROCEDURAL HISTORY
I.The Parties

Appellant Kitchen Connection is an Illinois corporation that manufactures and sells kitchen utensils. Appellant Ursula Kaiser (Kaiser) is the founder andPage 1149sole shareholder of Kitchen Connection. Appellant Magic Kitchen LLC is a California limited liability company that Kaiser formed in December 2002, shortly before filing this action.

Respondent The Pampered Chef is an Illinois-based company that sells kitchen tools through home parties. Respondents Goods Things International and Ten Mark Corporation are Taiwanese corporations that source products for overseas companies, including Pampered Chef.

II.Pampered Chefs Purchase of Tartmasters from Kitchen Connection

Doris and Jay Christopher formed Pampered Chef in 1980. From the mid-1980's until 1993, Pampered Chef purchased a variety of kitchen products from Kitchen Connection. One such product was the Tartmaster, a hand-operated metal device used to cut and crimp the edges of dough and bread to make tarts and crustless sandwiches. Pampered Chef purchased Tartmasters from Kitchen Connection in two sizes: 3-inch and 4-inch. Pampered Chef also purchased from Kitchen Connection a cookbook Kaiser authored called Pasta, Pies, and Pastries: Tart Recipes from around the World, which described recipes that could be made using the Tartmaster. The cookbook's back cover showed "3 easy steps" for making pasta, pies, and pastries using the Tartmaster: "fill," "cut `n seal," and "cook."

Pampered Chef sold Tartmasters to consumers in plastic bags labeled "The Pampered Chef Tartmaster." Kitchen Connection never required Pampered Chef to identify the Tartmaster as a Kitchen Connection product, and Pampered Chef apparently never did so.
III.Pampered Chefs Sourcing of the Cut-N-Seal from GoodThings and Ten Mark


In about 1992, Pampered Chef learned that the patent for the Tartmaster design had expired and the design was in the public domain. Subsequently, in early 1993, Pampered Chef stopped buying Tartmasters from Kitchen Connection. At about the same time, it began sourcing three-inch and four-inch versions of the product, which it called the Cut-N-Seal, from Good Things and Ten Mark in Taiwan. The Cut-N-Seal had the same basic design as the Tartmaster, but was made of stainless steel and used a different spring. Additionally, each Cut-N-Seal was imprinted with the words "Cut-N-Seal" and "The Pampered Chef." Pampered Chef sold Cut-N-Seals under the same product numbers it formerly had used with the three-inch and four-inch Tartmasters.Page 1150

In July 1993, Kaiser discovered that Pampered Chef was having copies of the Tartmaster made in Asia. On July 15, 1993, she sent a letter to Doris Christopher saying that she was "surprised to see that you are . . . carrying both the 3 [-inch] and the 4[-inch] Tartmaster," as well as shaped pancake molds that Pampered Chef formerly had purchased from Kitchen Connection. In the letter, Kaiser asserted patent rights to the pancake molds and warned that Pampered Chefs sale of those products was actionable patent infringement. However, she did not claim any intellectual property rights to the Tartmaster.

Between 1993 and 2003, Pampered Chef made a "substantial investment" in the Cut-N-Seal, which included traveling to Asia, promoting the product, and developing recipes for its use. In the late 1990's, Pampered Chef developed and marketed a three and a half-inch version of the Cut-N-Seal, and it subsequently stopped selling the three-inch and four-inch versions.

When the 3½-inch Cut-N-Seal was introduced in 2000, the product and its "use and care" instructions were marked "patent pending." No patent application was ever filed, however, and the "patent pending" designation was removed from the Cut-N-Seal in 2002 and from the use and care instructions in 2002 or 2003. After that time, Pampered Chef affixed a sticker stating "No patent pending are issued for this product" on erroneously marked products that remained in stock.

IV.The Present Action

Plaintiffs filed the present action in January 2003. The operative first amended complaint, filed May 1, 2003, alleged eight causes of action: (1) unfair competition in violation of Business and Professions Code section17200(section 17200) (first cause of action); (2) false advertising in violation of Business and Professions Code section17500(section 17500) (second cause of action); (3) trade dress infringement in violation of section 43 of the Lanham Act (15 U.S.C. § 1125) (third and fourth causes of action); (4) unfair competition and false advertising in violation of15 United States Code section 1125(fifth cause of action); (5) conspiracy to commit fraud (sixth cause of action); (6) conspiracy to interfere with contractual relations and prospective economic advantage (seventh cause of action); and (7) unjust enrichment (eighth cause of action).

Plaintiffs' primary factual allegation, on which all eight causes of action were based, was that the Cut-N-Seal infringed the Tartmaster's trade dress. Plaintiffs also alleged that defendants committed unfair trade practices andPage 1151false advertising by transacting business in California without obtaining a certificate of qualification from the Secretary of State and by imprinting the 3½-inch Cut-N-Seal "pat. pending," even though it never applied for a patent for that product. Plaintiffs sought injunctive and other equitable relief, "profits, damages, and costs in the amount to be proved at trial" and exemplary damages.

Plaintiffs dismissed the sixth and seventh causes of action without prejudice prior to trial. They dismissed the fifth cause of action immediately prior to opening statements.

V.The Trials and Judgment

A.The Jury Trial

The parties tried plaintiffs' remaining causes of action over 17 court days between May 24 and August 18, 2005. In the first phase of the trial, the parties tried to a jury the third and fourth causes of action for trade dress infringement under the Lanham Act and the eighth cause of action for unjust enrichment. In the second phase of the trial, the parties tried to the court the first cause of action for violation of section 17200 and the second cause of action for violation of section 17500.

At the close of plaintiffs' case before the jury, defendants filed motions for nonsuit. Good Things and Ten Mark sought nonsuit on the third, fourth, and eighth causes of action on the grounds that they were barred by the statute of limitations and laches. Pampered Chef sought nonsuit on the third and fourth causes of action on the ground that plaintiffs failed to establish essential elements of trade dress infringement and lacked standing. Each defendant joined, to the extent applicable, in the motions for nonsuit made by the other.

The court deferred ruling on the nonsuit motions. At the conclusion of testimony, the defendants renewed their motions for nonsuit and, in the alternative, also sought a directed verdict. The court heard argument and then granted the motions for nonsuit or, in the alternative, for directed verdict on the third, fourth, and eighth causes of action.

With regard to the statute of limitations and laches, the court concluded it was undisputed that defendants began manufacturing and distributing three-inch and four-inch Cut-N-Seals in 1993, and that Ursula Kaiser became aware of those activities no later than July 15, 1993. The court further found itPage 1152undisputed that defendants began manufacturing and selling three and a half-inch Cut-N-Seals in 2000, and that the three and a half-inch Cut-N-Seal was identical to the three-inch and four-inch versions except for its size.

The court found that under Ninth Circuit case law, a claim is presumed to be barred by laches if any part of the alleged wrongful conduct occurred outside the applicable limitations period. Here, the court said, the limitations period was three years. Thus, because plaintiffs waited 10 years to file suit — more than three times the limitations period — and failed to offer a legitimate excuse for their lengthy delay, their claims presumptively were barred by laches.

Furthermore, the court said, there was undisputed evidence of prejudice. Although Doris Christopher conceded she could not specifically quantify Pampered Chefs development costs, she testified that there were significant costs associated with contacting and developing relationships with manufacturers, traveling to Taiwan, creating molds and promotional materials, printing catalogs, and producing Cut-N-Seals. Moreover, there was evidence that Pampered Chef had purchased millions of Cut-N-Seals from Good Things. The court stated: "That shows a substantial investment in time in the manufacture of the devices, the 3-inch, 4-inch, and later 3-and-a-half inch, and a substantial investment of cost with respect to the cost of goods sold and a substantial investment in capital for producing those units as well as substantial investment in marketing and advertising. Those numbers speak for themselves with regard to substantial prejudice in waiting ten years to bring the lawsuit."

Finally, the court rejected plaintiffs' contention that there were triable issues of fact regarding defendants' alleged unclean hands. The court found that defendants had admitted copying plaintiffs' product, but said that the "act of copying which defendants have acknowledged . . . is not sufficient in and of itself to show unclean hands." Instead, "[t]here has to be willfulness and the intentional infringement on the rights, and that is a knowing infringement on the rights." Here, the court said, there was no evidence of knowing infringement. It explained: "[T]he evidence with regard to this is that plaintiff has not met any burden to establish a prima facie case that defendants knowingly intended to infringe on the rights of the plaintiffs. Doris Christopher testified that she understood that . . . her company had the right to produce the Cut-N-Seal and that she had made changes in it to make it stainless steel and that after she started manufacturing it, then she also found out that the plaintiff didn't have any patent rights in it in any event. However,Page 1153there is no evidence to support a claim that the defendants intentionally with knowledge of the plaintiffs' rights intended to infringe on the trade dress."

Thus, the court concluded: "[T]he claims in the third and fourth causes of action are beyond the statute of limitations period and beyond any laches period because it has been shown that there is unreasonable delay of ten years in bringing the lawsuit, that the delay has been prejudicial to the defendants, and that the plaintiff has not demonstrated any unclean hands on the part of the defendants to negate the implications of the statute of limitations and laches."

The court also addressed the asserted untimeliness of the eighth cause of action for unjust enrichment, which was asserted against Good Things and Ten Mark only. The court explained that the eighth cause of action essentially duplicated the third and fourth causes of action and thus was also barred by laches. Additionally, the court found that plaintiffs failed to demonstrate either a direct relationship between the plaintiffs and these defendants or a direct benefit conveyed by the plaintiffs to these defendants.1

B.The Court Trial

In the second phase of trial, the parties tried to the court the first and second causes of action for unfair competition and false advertising under sections 17200 and 17500. After plaintiffs rested, defendants made a motion for judgment. The court deferred ruling and heard additional evidence. After defendants rested, the court entered judgment for defendants on both causes of action. We discuss the trial court's analysis of these causes of action in detail in part II,post.

C.Entry of Judgment

The court entered judgment on September 16, 2005, and notice of entry of judgment was served September 22, 2005. The court denied plaintiffs' timely motions for new trial and to vacate the judgment on November 17, 2005.Page 1154

VI.The Attorney Fee Motion

Defendants moved for attorney fees under the Lanham Act on December 28, 2005. Plaintiffs opposed. On February 28, 2006, the trial court denied the motion. It explained that the Lanham Act permits an award of fees to the prevailing party only in "exceptional cases," and that a case is exceptional for purposes of the statute when it is "`"groundless, unreasonable, vexatious, or pursued in bad faith."'" In the present case, the court found, "the matter was intensively, with great effort and complexity litigated and brought to trial. The court does not find that the plaintiffs' claims are totally groundless or unreasonable, and the mere fact that the case had determinations based upon the statute of limitations does not mean that the case is groundless or unreasonable for the purpose of awarding attorneys' fees under section [sic]15 U.S.C. section 1117(a), and for that reason, the court is going to deny the motions for attorneys' fees."

Plaintiffs timely appealed from the judgment, and Good Things and Ten Mark filed a timely cross-appeal from the denial of their motion for attorney fees.
DISCUSSION
I.The Trial Court Properly Directed a Verdict for Defendants on theThird, Fourth, and Eighth Causes of Action

A.Standard of Review

"`A directed verdict may be granted only when, disregarding conflicting evidence, giving the evidence of the party against whom the motion is directed all the value to which it is legally entitled, and indulging every legitimate inference from such evidence in favor of that party, the court nonetheless determines there is no evidence of sufficient substantiality to support the claim or defense of the party opposing the motion, or a verdict in favor of that party. [Citations.]' (Howard v.Owens Corning(1999)72 Cal.App.4th 621,629-630[85 Cal.Rptr.2d 386];Newingv.Cheatham(1975)15 Cal.3d 351,358-359[124 Cal.Rptr. 193,540 P.2d 33].) This court decides de novo whether sufficient evidence was presented to withstand a directed verdict. (Brassinga v. City of MountainView(1998)66 Cal.App.4th 195,210[77 Cal.Rptr.2d 660].)" (Gelfov. Lockheed Martin Corp.(2006)140 Cal.App.4th 34,46-47[43 Cal.Rptr.3d 874].)
B.Third and Fourth Causes of Action: Federal Lanham ActClaims For Trade Dress Infringement


Plaintiffs' third and fourth causes of action allege trade dress infringement under section 43 of the Lanham Act (15 U.S.C. § 1125) in connectionPage 1155with the three-inch and four-inch Cut-N-Seals (third cause of action) and the three and a half-inch Cut-N-Seal (fourth cause of action). "[T]rade dress `refers to the "total image of a product" and may include features such as size, shape, color, color combinations, texture or graphics.'International Jensen, Inc. v. Metrosound U.S.A., Inc.,4 F.3d 819,822(9th Cir. 1993);Vision Sports, Inc. v. Melville Corp.,888 F.2d 609,613(9th Cir. 1989)." (Continental Laboratory Products, Inc. v. MedaxIntern., Inc.(S.D.Cal. 2000)114 F.Supp.2d 992,997; seeRoulo v.Russ Berne Co., Inc.(7th Cir. 1989)886 F.2d 931,935(Roulo).) The design of a product, as well as its packaging, both are part of its "trade dress." (Fuji Kogyo Co., Ltd. v. Pacific Bay Intern., Inc.(6th Cir. 2006)461 F.3d 675,683.) "A seller's adoption of a trade dress confusingly similar to a competitor's constitutes unfair competition that is actionable under section 43(a) of the Lanham Act." (Vision Sports v.Melville Corp., supra,888 F.2d at p. 613, citingBlau Plumbing, Inc. v.S.O.S. Fix-It, Inc.(7th Cir. 1986)781 F.2d 604,608.)2

The purpose of trademark and trade dress protection is to enable a business "to identify itself efficiently as the source of a given product through the adoption of a mark which may be in the form of a slogan, symbol, ornamental design or other visual insignia." (Roulo, supra,886 F.2d at pp. 935-936.) However, trade dress protection "is not intended to create patent-like rights in innovative aspects of product design. [Citation.] Thus, trade dress protection, unlike patent law . . ., does not foster innovation by preventing reverse engineering or copying of innovative product design features. [Citation.] `Trade dress protection must subsist with the recognition that in many instances there is no prohibition against copying goods and products.' [Citation.] Therefore, trade dress protection extends only to incidental, arbitrary or ornamental product features which identify the product's source. [Citation.]" (Shire US Inc. v. Barr Laboratories, Inc.(3d Cir. 2003)329 F.3d 348,353.) A mark or trade dress that is fanciful, arbitrary, or otherwise distinctive is given protection more readily than a generic or descriptive trademark or trade dress that is functional since appropriation of generic words, marks, or dress would prevent producers from accurately describing or denoting the quality or content of their goods. (Roulo, supra,886 F2d at pp. 935-936.)Page 1156

On appeal, plaintiffs contend that the trial court erred in granting defendants' motions for directed verdict because there are triable issues of fact as to whether plaintiffs' trade dress claims were timely. Defendants disagree; they also contend in the alternative that plaintiffs' trade dress claims fail on the merits.

As a preliminary matter, we must determine whether the timeliness of plaintiffs' claims should be measured by the legal defense of the statute of limitations or the equitable defense of laches. Plaintiffs contend that under the law of many circuits, only laches applies to Lanham Act claims; defendants urge that both laches and statute of limitations apply.

As applied to Lanham Act claims, "[t]he proper interplay between laches and the statute of limitations . . . is somewhat elusive." (JarrowFormulas, Inc. v. Nutrition Now, Inc.(9th Cir. 2002)304 F.3d 829,836(Jarrow Formulas), citing Rest.3d Unfair Competition, § 31, com. a [discussing the uncertain role of the statute of limitations for Lanham Act claims].) Although the Lanham Act contains no explicit statute of limitations, some federal cases hold that Lanham Act claims are governed by the statute of limitations applicable to analogous state law claims. (E.g.,Karl Storz Endoscopy America v. Surgical Tech.(9th Cir. 2002)285 F.3d 848,857["Storz's Lanham Act claims are subject to a three-year statute of limitations which began to run upon Storz's actual or constructive knowledge of the wrong"].) Other cases disagree, suggesting that since "[s]ection 43(a) monetary relief is `subject to the principles of equity,'15 U.S.C. § 1117(a)" and "injunctive relief is similarly available `according to the principles of equity [,]' (id.) § 1116(a)," Congress might have intended that laches be the sole timeliness bar to suit. (Jarrow Formulas, supra,304 F.3d at p. 836.)

Federal appellate authority thus is split as to whether a statute of limitations applies to Lanham Act claims or whether, instead, laches is the only applicable timeliness defense. However, we need not resolve the issue. Because we conclude that plaintiffs' claims are barred by the equitable defense of laches, we need not decide whether they also are barred by the statute of limitations.

Laches is an equitable time limitation on a party's right to bring suit, resting on the maxim that "equity aids the vigilant, not those who sleep on their rights." (Lyons Partnership, L.P. v. Morris Costumes,Inc.(4th Cir. 2001)243 F.3d 789,797-798(Lyons); see alsoJarrowFormulas, supra,304 F.3d at p. 835["`one who seeks the help of a court of equity must not sleep on his rights'"].) It is well established that laches is a valid defense to Lanham Act claims. (Jarrow Formulas, supra,304 F.3d at p. 835;GoTo.Com., Inc. v. WaltPage 1157Disney Co.(9th Cir. 2000)202 F.3d 1199,1209;Kason Industries v.Component Hardware Group(11th Cir. 1997)120 F.3d 1199,1203.)

A defendant must demonstrate three elements to successfully assert a laches defense: (1) delay in asserting a right or a claim; (2) the delay was not reasonable or excusable; and (3) prejudice to the party against whom laches is asserted. (Miller v. Glenn Miller Productions, Inc.(9th Cir. 2006)454 F.3d 975,997;Jarrow Formulas, supra,304 F.3d at pp. 835,838;Kason Industriesv.Component Hardware Group, supra,120 F.3d at p. 1203.) We consider each of these three elements below.

1.Delay

The first element of laches is delay, as measured by the period "from when the plaintiff knew (or should have known) of the allegedly infringing conduct, until the initiation of the lawsuit in which the defendant seeks to counterpose the laches defense." (Danjaq LLC v. SonyCorp.(9th Cir. 2001)263 F.3d 942,952(Danjaq LLC.)) If a Lanham Act claim is filed within the analogous state limitations period — here, no more than four years3— the strong presumption is that laches is inapplicable. If the claim is filed after the analogous limitations period has expired, the presumption is that laches bars the suit. (DanjaqLLC, at p. 952; see alsoMiller v. Glenn Miller Productions, Inc., supra,454 F.3d at p. 997;Lyons, supra,243 F.3d at p. 799;Hot Wax, Inc. v.Turtle Wax, Inc.(7th Cir. 1999)191 F.3d 813,821(Hot Wax).)Three-Inch and Four-Inch Cut-N-Seals.It is undisputed that plaintiffs learned that Pampered Chef was selling three-inch and four-inch Cut-N-Seals no later than July 1993, when Ursula Kaiser "saw a catalog and saw that The Pampered Chef copied my Tartmaster." Because plaintiffs did not file the present action for nearly 10 years — well after either a three-year or four-year statute of limitations would have run — it presumptively is untimely.

Plaintiffs contend that although the alleged trade dress infringement began in 1993, their claims nonetheless are timely because "where a civil conspiracyPage 1158is properly alleged and proved, the statute of limitations `does not begin to run on any part of plaintiff[s'] claims until the "last overt act" pursuant to the conspiracy has been completed.'" Whatever the merits of this contention generally, it has no application here. Plaintiffs initially pled two causes of action for conspiracy — to commit fraud (sixth cause of action) and to interfere with contractual relations and prospective economic advantage (seventh cause of action) — but dismissed them prior to trial. Moreover, plaintiffs' appellate briefs do not cite any evidence of a conspiracy. Thus, plaintiffs cannot pursue this issue on appeal. (Levin v. Ligon(2006)140 Cal.App.4th 1456,1486[45 Cal.Rptr.3d 560] ["It is not the duty of a reviewing court to search the record for evidence on a point raised by a party whose brief makes no reference to the specific pages where the evidence can be found"].)

Plaintiffs also contend that even if some of their infringement claims are untimely, they nonetheless are entitled to damages sustained within the applicable limitations period. We do not agree. Under federal law, when evaluating whether laches bars a damages claim, a continuing tort is considered a single act rather than a series of separate acts. InA.C.Aukerman Co. v. R.L. Chaides Const. Co.(Fed. Cir. 1992)960 F.2d 1020, for example, the court rejected the plaintiff's contention that some of defendant's alleged acts of patent infringement were not barred by laches because they occurred within the applicable limitations period. The court explained: "[Plaintiff] asserts that it is improper to utilize laches as a defense to completely bar recovery of prefiling damages flowing from a continuing tort, such as patent infringement. We understand [plaintiff] to be arguing that, because each act of infringement is deemed a separate claim, the laches defense, like a statute of limitations, must be established separately with respect to each such act. [Citation.] [¶] [Plaintiff's] theory conflicts with the precedent of the Supreme Court in which laches has been applied against continuing torts. . . . In those cases, as well as in our precedent and that of other circuits, laches has been viewed as a single defense to a continuing tort up to the time of suit, not a series of individual defenses which must be proved as to each act of infringement, at least with respect to infringing acts of the same nature. [Citation.] To that extent, continuing tortious acts may be deemed to constitute a unitary claim." (Id.at p. 1031.)

Many other federal courts have concluded similarly. (E.g.,JarrowFormulas, supra,304 F.3d at p. 837, quotingDanjaq LLC, supra,263 F.3d at p. 953["the presumption of laches is triggered if any part of the claimed wrongful conduct occurred beyond the limitations period. To hold otherwise would `effectively swallow the rule of laches, and render it a spineless defense.'"];Bridgestone/Firestone v. Auto. Club deI'Quest(Fed. Cir. 2001)Page 1159245 F.3d 1359,1364["The Automobile Club also argues that laches can not apply to its [Lanham Act] § 2(a) claim because Bridgestone's trademark use of LEMANS is a `continuing wrong' for which every use is a new injury. However, when the obligation arises to assert an objection to a trademark registration, that obligation is not postponed by continued use of the trade-mark."];Hot Wax, supra,191 F.3d at p. 821["Without the availability of the application of laches to a claim arising from a continuing wrong, a party could, theoretically, delay filing suit indefinitely. It would certainly be inequitable to reward this type of dilatory conduct and such conduct would necessarily warrant application of laches in appropriate circumstances."].) Thus, if defendants' alleged trade dress infringement began outside the limitations period, plaintiffs may not recover damages allegedly suffered within that period.

Plaintiffs also claim that even if their Lanham Act claims are otherwise barred by laches, laches cannot bar their claim for prospective injunctive relief. Plaintiffs are correct thatLyons, supra,243 F.3d at page 799, supports this proposition, but we think the better rule is articulated in other federal appellate decisions that hold that the presumption of laches is triggered ifanypart of the claimed wrongful conduct occurred beyond the limitations period. (E.g.,JarrowFormulas, supra,304 F.3d at p. 840[rejecting plaintiff's contention that even if laches were otherwise applicable, it should not bar claim for prospective injunctive relief];Danjaq LLC, supra,263 F.3d at pp. 959-960[district court properly applied laches to bar claim for prospective injunctive relief where "the feared future infringements are identical to the alleged past infringements"];E-Systems, Inc. v. Monitek, Inc.(9th Cir. 1983)720 F.2d 604,607["Laches can bar recovery in trademark or trade-name actions where injunctive relief is sought"].) Thus, plaintiffs' request for prospective injunctive relief does not alter our conclusion that their claims regarding the three-inch and four-inch Cut-N-Seals presumptively are untimely.Three and a Half-Inch Cut-N-Seal.Plaintiffs contend that even if their infringement claims are untimely as to the three-inch and four-inch versions of the Cut-N-Seal, they are timely as to the three and a half-inch version because Pampered Chef did not introduce it until April 2000, less than three years before this suit was filed. We do not agree.

As we have concluded, the relevant delay for laches purposes is "`the period from when the plaintiff knew (or should have known) of theallegedlyinfringing conduct.'" (Tillamook Country Smoker v. TillamookCy. Creamery(D.Or. 2004)311 F.Supp.2d 1023,1032(Tillamook), quotingDanjaq LLC, supra,263 F.3d at 952.) Thus, where a family of products is alleged toPage 1160infringe on a competitor's trademark or trade dress, courts have held that delay is measured from the time the plaintiff became aware of "the conduct which [it] claims is infringement," not the introduction of each individual product. (Tillamook, at p. 1032.)

InTillamook, supra,311 F.Supp.2d 1023, the defendant began using its allegedly infringing trade name more than 30 years before plaintiff filed suit. The defendant claimed that the plaintiffs suit was barred by laches; the plaintiff contended that the delay period for laches purposes began just five years before suit was filed, when the defendant began using its trade name in connection with a particular package design. (Id.at pp. 1030-1033.) The court rejected the plaintiffs analysis and held the suit barred by laches. It explained that when evaluating the timeliness of an infringement claim, the relevant delay is the period during which the plaintiff knew about the conduct that forms the "crux of [its] infringement claim." (Id.at pp. 1031-1032.) Because the "crux" of the plaintiffs infringement claim was the defendant's use of the trade name Tillamook Country Smoker,notits use of a particular package design, its claim "effectively is `the same trademark infringement case it had' well over ten years ago" and, hence, was barred by laches. (Id.at p. 1037; see alsoDeere Co.v.MTD Holdings Inc.(S.D.N.Y. 2004) 2004 WL 324890.)

In the present case, the "crux" of plaintiffs' infringement claim is the design of the Cut-N-Seal — which plaintiffs contend "slavishly copied" the Tartmaster design — not the product's size. It was undisputed at trial that the design of the three and a half-inch Cut-N-Seal was the same as its three-inch and four-inch predecessors. Indeed, Kaiser herself conceded that the three and a half-inch Cut-N-Seal had the "same design" as the three-inch and four-inch versions and that there is "no difference" between the three-inch and three and an half-inch Cut-N-Seals. Accordingly, since the Cut-N-Seal's size is irrelevant to plaintiffs' trade dress claim, the claim as to the three and a half-inch Cut-N-Seal "effectively is `the same . . . infringement case it had'" 10 years ago. (Tillamook, supra,311 F.Supp.2d at p. 1037.) Thus, it too presumptively is barred by laches.

2.Reasonableness of the Delay

The next element of laches is the reasonableness of the delay. "Delay has been held permissible, among other reasons, when it is necessitated by the exhaustion of remedies through the administrative process, [citation]; when it is `used to evaluate and prepare a complicated claim,' [citation]; and when its purpose is `to determine whether the scope of proposed infringement will justify the cost of litigation,' [citation]. By contrast, delay is impermissible when its purpose is to capitalize on the valuePage 1161of the alleged infringer's labor, by determining whether the infringing conduct will be profitable." (Danjaq LLC, supra,263 F.3d at p. 954.)

Here, plaintiffs have presented no legally sufficient justification for their delay. Their only claims in this regard are that Pampered Chef "was put on notice as early as July 15, 1993 that [Kitchen Connection] considered the knockoff Cut-N-Seal product to be violative of its rights" and that Pampered Chef and Kitchen Connection "`had already been litigating claims' against each other for at least `six years.'" Plaintiffs suggest no reason why litigating other matters or putting Pampered Chef on notice that they considered its conduct improper should justify delay in litigating this matter, nor do they cite any authority for the proposition that other litigation between the parties is relevant to the reasonableness of delay. Accordingly, we find that the trial court properly concluded that plaintiffs' delay was unreasonable as a matter of law.

3.Prejudice to Defendants

The final element of laches is prejudice. "`A defendant has been prejudiced by a delay when the assertion of a claim available some time ago would be "inequitable" in light of the delay in bringing that claim . . . [and] ensues when a defendant has changed his position in a way that would not have occurred if the plaintiff had not delayed.'" (HotWax, supra,191 F.3d at p. 824; see alsoDanjaq LLC, supra,263 F.3d at p. 955["A defendant may . . . demonstrate prejudice by showing that it took actions or suffered consequences that it would not have, had the plaintiff brought suit promptly"].)

Plaintiffs' opening brief asserts in an argument heading that defendants were not prejudiced by the nearly 10-year delay in bringing the present suit, but it neither makes an argument nor cites any authority in support. The contention therefore is waived. (E.g.,MoultonNiguel Water Dist. v. Colombo(2003)111 Cal.App.4th 1210,1215[4 Cal.Rptr.3d 519] (Moulton) ["Contentions are waived when a party fails to support them with reasoned argument and citations to authority"];Badie v. Bank of America(1998)67 Cal.App.4th 779,784-785[79 Cal.Rptr.2d 273] (Badie) ["When an appellant fails to raise a point, or asserts it but fails to support it with reasoned argument and citations to authority, we treat the point as waived"].) The waiver is not cured by argument and citations in plaintiffs' reply brief: "It is elementary that points raised for the first time in a reply brief are not considered by the court." (Levin v. Ligon, supra, 140 Cal.App.4th at p. I486; see alsoCampos v.Page 1162Anderson(1997)57 Cal.App.4th 784,794, fn. 3 [67 Cal.Rptr.2d 350] [same].)

Even if we did not deem plaintiffs' "no prejudice" argument waived, we nonetheless would reject it. Courts have found prejudice sufficient to support a finding of laches where, as a result of a plaintiff's delay in bringing suit, a defendant has invested resources in developing and marketing a product. InHot Wax, supra,191 F.3d 813, the plaintiff, a car wax manufacturer, sued a competitor for misrepresenting the qualities of its competing car wax product. The district court entered summary judgment for the defendant, concluding that laches barred plaintiff's claim. (Id.at p. 818.) The appellate court affirmed, finding clear prejudice to defendant. It explained: "Hot Wax permitted Turtle Wax's advertising and the development of its products to go unchecked for well over a ten- to twenty-year period. During this time, Hot Wax sat idly by and chose not to challenge Turtle Wax's use of the term `wax' with respect to its products, and Turtle Wax invested significant amounts of time and money in product development and advertising. . . . Had Hot Wax successfully pressed its claims in a timely manner, Turtle Wax certainly could have invested its time and money in other areas or simply renamed its products. Accordingly, in light of the extreme length of the unreasonable delay by Hot Wax, we conclude that the district court did not err in concluding that Turtle Wax was prejudiced by this delay." (Id.at p. 824, fn. omitted.)

The court reached a similar conclusion inJarrow Formulas, supra,304 F.3d 829. There, a supplier of nutritional supplements waited seven years to sue a competitor for allegedly making false claims about its product, PB8. (Id.at pp. 832-833.) The trial court granted the defendant's motion for summary judgment, concluding that the plaintiff's claims were barred by laches as a matter of law. (Id.at p. 833.) The Ninth Circuit affirmed. It concluded that the defendants had demonstrated prejudice as a matter of law: "Nutrition Now has invested enormous resources in tying PB8's identity to the challenged claims. After waiting for several years, Jarrow now seeks to compel Nutrition Now to abandon its presentation of PB8, forcing it to adopt a materially different characterization of its product. If Jarrow had filed suit sooner, Nutrition Now could have invested its resources in shaping an alternative identity for P88 in the minds of the public. [Citations.]" (Id.at p. 839; see alsoConopco, Inc. v. Campbell Soup Co.(2d Cir. 1996)95 F.3d 187,192-193[finding prejudice because defendant could have chosen an alternative marketing position if the plaintiff had filed suit earlier].)

In the present case, the trial court found the evidence undisputed that defendants were prejudiced by plaintiffs' 10-year delay in bringing suit. We agree. The undisputed evidence establishes that plaintiffs did not allege thatPage 1163the Cut-N-Seal infringed plaintiffs' trade dress rights until they filed the present suit in 2003. Between 1993 and 2003, Pampered Chef invested significant resources in developing and selling the Cut-N-Seal, which included traveling to Taiwan, producing millions of Cut-N-Seals, developing the three and a half-inch version of the product, creating recipes, printing catalogs, and promoting the product. As inHot WaxandJarrow Formulas, had plaintiffs pressed their claims in a timely manner, Pampered Chef could have invested its resources in other areas or altered the Cut-N-Seal in a way that would have avoided the present suit. Thus, we agree with the trial court that the evidence is undisputed that Pampered Chef was prejudiced by plaintiffs' lengthy delay in bringing suit.

Plaintiffs urge that underCalifornia Western School of Law v.California Western University(1981)125 Cal.App.3d 1002,1007[178 Cal.Rptr. 685], defendants' expenditures on the Cut-N-Seal after they knew of plaintiffs' claim do not constitute prejudice because "`[i]f the defendant continues his act, after due warning, he does so at his own risk.'" Thus, plaintiffs suggest, because Pampered Chef "was put on notice as early as July 15, 1993 that [plaintiffs] considered the knockoff Cut-N-Seal product to be violative of its rights," their costs associated with manufacturing and selling the product after that date are not evidence of prejudice. The contention is unpersuasive. Plaintiffs do not identify any evidence that plaintiffs advised defendants of their trade dress claim in July 1993; Kaiser's July 15, 1993 letter to Doris Christopher, on which plaintiffs rely, asserted at most that Pampered Chefs sale of the Cut-N-Seal and other products constitutedpatentinfringement. Indeed, the undisputed evidence at trial was that the first time plaintiffs asserted a trade dress infringement claim was when they filed the present suit in January 2003. Thus, even ifCalifornia Westernarticulates the applicable law, it does not suggest a triable issue of fact as to prejudice.

Plaintiffs also urge thatGrand Canyon Trust v. Tucson Elec. Power Co.(9th Cir. 2004)391 F.3d 979supports the proposition that there was no prejudicial reliance in the present case, but again we do not agree.4There, the defendants built a coal-powered electric generating plant without receiving a proper permit. (391 F.3d at p. 982.) Twenty-four years later, the Grand Canyon Trust sued to enforce the federal Clean Air Act. (Ibid.) Reversing the district court, the Ninth Circuit held that laches did not bar the suit because the defendant had not taken any action in reliance on the plaintiffs delay. To the contrary, the court concluded that "Grand Canyon's delay worked to the benefit of Tucson Electric because it allowed Tucson Electric the opportunityPage 1164to recover some or all of its investment in Springerville Units 1 and 2 before this suit was filed. By contrast, if Grand Canyon had brought this action immediately after construction on each Unit was completed, and had the court held that Tucson Electric was required to replace the equipment it had just installed, Tucson Electric's loss would have been total." (Id.at pp. 988-989.)

The present case differs in significant respects. In contrast toGrandCanyon Trust, where the defendant apparently did not expend additional resources in the plant as a result of plaintiffs delay, here defendants produced millions of Cut-N-Seals as a direct result of plaintiffs' delay. Further, in 2000, defendants developed, and subsequently produced and marketed, a new three and a half-inch version of the product. Thus, plaintiffs' assertion that "[Pampered Chef] and [Good Things] simply did nothing to change their course of action in reliance upon [Kitchen Connection's] not filing trade dress claims until January 2003" is not supported by the evidence. And, while inGrand Canyon Trustthe delay worked to the defendant's benefit because it allowed the defendant to recoup some of itspriorinvestment in the power plants, here the delay had the opposite effect because it resulted in defendants'continuedinvestment in the Cut-N-Seal.

We also reject plaintiffs' suggestion that defendants "failed to identify any specific evidence of incremental costs attributable to the Cut-N-Seal." As the trial court noted, the evidence of Pampered Chefs investment in the Cut-N-Seal was undisputed. Further, as the trial court also found, while Pampered Chef could not specifically quantify the costs of developing and marketing the Cut-N-Seal, Pampered Chef did quantify its production costs. The undisputed evidence was that Pampered Chef paid $1.40 to $1.70 per unit for the three-inch and four-inch Cut-N-Seals, and approximately $1.45 per unit for the three and a half-inch Cut-N-Seals. Between 1993 and 2003, Pampered Chef sold hundreds of thousands of Cut-N-Seals, representing an investment of millions of dollars in the product. Had the present suit been brought earlier, Pampered Chef could have invested these sums in other products.

Finally, we dismiss as waived plaintiffs' contention that the trial court's exclusion of testimony and documents relevant to the issue of prejudice was reversible error. Plaintiffs claim that they would have been able to rebut defendants' evidence of prejudice had they been permitted to introduce the testimony of financial experts Stan Smith and Michael Mische, as well as "various financial records of [Pampered Chef] relevant to the issue of lack of prejudice," including "certain financial documents produced via verified document request responses." However, plaintiffs have not demonstrated that they made an offer of proof at trial, nor have they given this courtPage 1165any information about the substance of the documents or testimony that would allow us to conclude that their exclusion was erroneous. "`It is the burden of the proponent of evidence to establish its relevance through an offer of proof or otherwise,' and a specific offer of proof is necessary in order to preserve an evidentiary ruling for appeal. [Citation.]" (People v. Brady(2005)129 Cal.App.4th 1314,1332[29 Cal.Rptr.3d 286].) Because plaintiffs apparently failed to make an offer of proof, the issue was not preserved for appeal.

4.Unclean Hands

Plaintiffs contend that even if laches otherwise would bar their claims, defendants cannot assert it because they have unclean hands. Specifically, plaintiffs assert that defendants (1) intentionally copied the Tartmaster's design; (2) falsely marked the three and a half-inch Cut-N-Seal "pat. pending," and (3) omitted Kaiser's prior use of the phrase "cut `n seal" from their trademark application.

Plaintiff is correct that in appropriate cases, unclean hands has been held to bar a laches defense to Lanham Act claims. Specifically, as applied to infringement claims under the Lanham Act, unclean hands has been held to bar the assertion of laches by a "willful" or "deliberate" infringer. (E.g.,Danjaq LLC, supra,263 F.3d at pp. 956-957;HermèsIntern, v. Lederer de Paris Fifth Ave.(2d Cir. 2000)219 F.3d 104,107.)5However, while the willfulness exception has been held to apply where a defendant intentionallyinfringedon another's rights, it does not extend, as plaintiffs suggest, to mere intentionalcopying.Rather, "`[t]o establish willful infringement, a plaintiff must prove by clear and convincing evidence that the defendant acted without a reasonable belief that its action avoided infringement.'" (State ContractingEngineering Corp. v. Condotte America, Inc.(Fed. Cir. 2003)346 F.3d 1057,1063, quotingCrystal Semiconductor v. TriTech Microelectronics(Fed. Cir. 2001)246 F.3d 1336,1351; see alsoDanjaq LLC, supra,263 F.3d at p. 957["for purposes of the willfulness exception to laches, . . . the term `willful'Page 1166refers to conduct that occurs `with knowledge that the defendant's conduct constitutes . . . infringement'"];Jarrow Formulas, supra,304 F.3d at p. 842, italics added ["A plaintiff can escape laches under the unclean hands doctrine only if the court is left with a firm conviction that the defendant actedwith a fraudulent intentin making the challenged claims"];Hermes Intern, v. Lederer de Paris Fifth Ave.,supra,219 F.3d at p. 107, italics added ["It is well established that `laches is not a defense against injunctive relief when the defendant intendedthe infringement'"];Hall v. Aqua Queen Mfg., Inc.(Fed. Cir. 1996)93 F.3d 1548,1555["The test of willful infringement is `whether, under all the circumstances, a reasonable person would prudently conduct himself with any confidence that a court might hold the patent invalid or not infringed'"].) In other words, to come within the "willfulness" exception, the defendant must know not only that its product mimics another, but that its mimicking of that product constitutes trade dress infringement.

Here, plaintiffs have not cited any evidence that defendants intentionally infringed on plaintiffs' trade dress. Plaintiffs are correct that defendants "admitted that they intentionally copied the exterior design of the Tartmaster" and "the same catalog number was used," but that is not sufficient to demonstrate willful trade dress infringement. Rather, as we have noted, plaintiffs must demonstrate that defendants both (1) intentionally copied their trade dressand(2) did so with knowledge that the copying constituted trade dress infringement. Because plaintiffs have not identified any evidence that would support the second element (i.e., knowledge of infringement), we conclude that the trial court properly found no triable issues of fact as to willfulness.

Plaintiffs also assert that defendants had unclean hands because they erroneously stamped the three and a half-inch Cut-N-Seal "pat. pending" and filed a trademark registration for the name "Cut-N-Seal" without disclosing that the phrase "Cut `N Seal" appeared on the back cover of Kaiser's cookbook Pasta, Pies and Pastries. The trial court correctly concluded that these assertions, even if correct, would not defeat defendants' laches defense. "The unclean hands doctrine `closes the doors of a court of equity to one tainted with inequitableness or bad faithrelative to the matter in which he seeks relief" (Jarrow Formulas, supra,304 F.3d at p. 841, quotingPrecision Co. v. Automotive Co., supra,324 U.S. at p. 814.) In other words, "`misconduct in the abstract, unrelated to the claim to which it is asserted as a defense,'" does not bar a laches defense. (Jarrow Formulas, supra,304 F3d at p. 841, quotingRepublic Molding Corp. v. B. W. Photo Utils.(9th Cir. 1963)319 F.2d 347,349.) "What is material is not that the plaintiffs hands are dirty, but that he dirtied them in acquiring the right he now asserts, or that the manner of dirtying renders inequitable the assertion of such rights against the defendant." (Republic Molding Corp. v. B. W. Photo Utils.,supra,319 F.2d at p. 349.)Page 1167

Here, plaintiffs have not suggested any way in which defendants acquired any rights relevant to plaintiffs' trade dress infringement claim through the alleged misuse of the "pat. pending" designation or use of the "Cut-N-Seal" trade name. This case thus resembles others in which courts rejected claims of unclean hands because although the alleged misconduct concerned theproductas to which rights were asserted, it did not concern therightsto those products that were the subject of litigation. (See, e.g.,Tveter v. AB Turn-O-Matic(9th Cir. 1980)633 F.2d 831,839[unclean hands doctrine did not bar judicial enforcement of plaintiffs trademark rights in ticket dispenser, notwithstanding defendant's contention that plaintiff had falsely marked dispenser "patent pending": "No relationship is suggested between appellees' asserted misuse and the acquisition of appellees' trademark rights; no other reason, arising out of the misuse, is advanced that would make it inequitable to enforce those rights"];Republic MoldingCorp. v. B. W. Photo Utils., supra,319 F.2d at pp. 348-351[unclean hands doctrine did not bar plaintiffs patent infringement and unfair competition claims where the conduct found to constitute unclean hands — marking product "patent pending." although no patent had been sought — was unconnected to defendant's misconduct].)6

For all these reasons, we conclude that the trial court properly granted a directed verdict as to the third and fourth causes of action for trade dress infringement.

C.Eighth Cause of Action: Unjust Enrichmentfn*Plaintiffs urge that the eighth cause of action for unjust enrichment is fundamentally legal, not equitable, and that it should have been submitted to a jury. However, the trial court took the unjust enrichment claim from the jury because it concluded there were no triable issues of material fact as to the claim,notbecause plaintiffs' claim was equitable in nature. Plaintiffs make no argument and cite no authority for the proposition that the directed verdict was improperly granted; thus the issue is waived on appeal. (Moultonsupra,111 Cal.App.4th at p. 1215;Badie, supra,67 Cal.App.4th at pp. 784-785; see alsoBerger v. California Ins.Guarantee Assn.(2005)128 Cal.App.4th 989,1007[argument waived because appellants "fail to make a coherent argument or cite any authority to support their contention, nor do they specify any facts they maintain would state a cause of action"].)II. The Trial Court Did Not Err in Entering Judgment for the Defendantson the First and Second Causes of ActionActing as trier of fact, the trial court granted judgment for defendants on the first and second causes of action, for unfair competition and false advertising under sections 17200 and 17500. We find no error.A. Standard of Review"When the trial court has resolved a disputed factual issue, the appellate courts review the ruling according to the substantial evidence rule. If the trial court's resolution of the factual issue is supported by substantial evidence, it must be affirmed.' [Citation.] In applying the substantial evidence standard of review, "the power of an appellate court begins and ends with a determination as to whether there is any substantial evidence, contradicted or uncontradicted," to support the findings below. [Citation.] We must therefore view the evidence in the light most favorable to the prevailing party, giving it the benefit of every reasonable inference and resolving all conflicts in its favor in accordance with the standard of review so long adhered to by this court.' [Citation.]" (Escamilla v. California Dept. of Corrections andRehabilitation(2006)141 Cal.App.4th 498, 514.)7B. First Cause of Action: Unfair Competition (Section 17200)Section 17200 prohibits unfair competition, including unlawful, unfair, and fraudulent business acts. (Korea Supply Co. v. LockheedMartin Corp.(2003)29 Cal.4th 1134,1143.) Plaintiffs' first cause of action alleges that defendants engaged in unfair competition in violation of section 17200 in three ways: (1) selling Cut-N-Seal products that infringed plaintiffs' trade dress rights; (2) transacting business in California without a certificate of qualification; and (3) making 3½-inch Cut-N-Seal products "pat. pending." The court noted that because claims brought pursuant to section 17200 are equitable in nature, they do not support a damages award. Further, plaintiffs were not entitled to restitution or disgorgement because there was no evidence they had an ownership interest in defendants' profits. Finally, plaintiffs were not entitled to an injunction. Thus, there was no relief to which plaintiffs were entitled. As we now explain, each of the trial court's rulings is supported by substantial evidence. With regard to plaintiffs' claim that defendants violated section 17200 by infringing plaintiffs' trade dress rights, plaintiffs stipulated that the trial court's statute of limitations/laches ruling applied equally to section 17200 claims. Plaintiffs' counsel stated, "we appreciate the fact that your rulings as to trade dress, statute of limitations, and laches would apply and carry over as to the first cause of action." Later counsel agreed, "we acknowledged that the ruling on laches and the time issues would apply." Thus, any error in extending the court's statute of limitations/laches ruling to plaintiffs' section 17200 claim was invited error. "When a party by his conduct induces the commission of an error, he is estopped from asserting it as a ground for reversal. [Citation.]' (Kardly v. State Farm Mut. Auto. Ins. Co.(1995)31 Cal.App.4th 1746,1750.)" (R B Auto Center, Inc. v. FarmersGroup, Inc.(2006)140 Cal.App.4th 327, 350.) Plaintiffs next claim that defendants failed to acquire a certificate of qualification. Section2105of the Corporations Code provides that a foreign corporation shall not "transact intrastate business" without obtaining a certificate of qualification from the Secretary of State. Corporations Code section191defines "transact[ing] intrastate business'" as "entering into repeated and successive transactions of its business in this state," but provides that a foreign corporation shall not be considered to be transacting intrastate business solely by reason of, among other things, "[e]ffecting sales through independent contractors" or "[s]oliciting or procuring orders, whether by mail or through employees or agents or otherwise, where those orders require acceptance outside this state before becoming binding contracts." (Corp. Code, §191, subd. (c)(5), (6).) The trial court concluded that Pampered Chef had not transacted intrastate business, and thus was not required to obtain a certificate of qualification, because (1) Pampered Chef did business in California solely through independent contractors, and (2) orders placed with Pampered Chef in California were subject to acceptance in Illinois. Plaintiffs do not attempt to demonstrate that the trial court's conclusions were not supported by substantial evidence; instead, they cite to evidence that they contend would have supported a judgment in their favor. This is insufficient to sustain their burden to demonstrate error. "[A]ppellants who challenge the decision of the trial court based upon the absence of substantial evidence to support it "are required to set forth in their briefallthe material evidence on the point andnotmerely their own evidence.Unless this is done the error is deemed waived."'" (Nwosu v. Uba(2004)122 Cal.App.4th 1229,1246.) Here, because plaintiffs fail to discuss all evidence material to their contentions, their claim of lack of substantial evidence is waived. (E.g.,State Farm Fire Casualty Co. v. Jioras(1994)24 Cal.App.4th 1619,1625-1626fn. 4.)8It is undisputed that between 2000 and approximately 2002, Pampered Chef marked the 3½-inch Cut-N-Seal "pat. pending," but that it never sought a patent in connection with this product. However, for a number of reasons, the trial court concluded plaintiffs were not entitled to relief. It found that because a section 17200 claim is equitable in nature, damages are not recoverable. Further, the court determined that plaintiffs were not entitled to restitutionary disgorgement underKoreaSupply Co. v. Lockheed Martin Corp., supra,29 Cal.4th 1134, because there was no evidence that any of defendants' profits represent monies given by plaintiffs to defendants. Finally, the trial court found that it was not appropriate to enjoin the challenged conduct because there was no evidence that it was likely to recur. The court explained: "There is no evidence that has been presented to the court of any threat of the misuse of the term patent pending' again by Pampered Chef or that patent pending' will be used in any fashion in the future, so there is not any immediate threatened conduct that has been substantiated by the evidence. All we are talking about is past conduct that has been completed and that there is corrective action that has been taken to ameliorate any misinformation. Since the conduct relating to the mislabeling on the 3-and-a-half-inch Cut-N-Seal with the words patent pending' is no longer ongoing activity, there is no threatened activity to continue mislabeling [sic] and the corrective action has been taken. There is no evidence that this conduct is likely to recur, and, therefore, under these circumstances, it does not appear appropriate to issue an injunction to prohibit conduct that has already ceased and has not taken place for over two years and there is no evidence of threat of recurring. Therefore, the court does not find it appropriate to issue an injunction." Plaintiffs make no argument and cite no evidence to suggest that the trial court abused its discretion in concluding that neither restitutionary disgorgement nor an injunction were appropriate under the facts of this case. Thus, the issue is waived. (E.g.,Moulton, supra,111 Cal.App.4th at p. 1215;Badie, supra,67 Cal.App.4th at pp. 784-785.)9C. Second Cause of Action: False Advertising (Section 17500)Business and Professions Code section17500prohibits "untrue or misleading" statements in connection with the sale of goods or services. Plaintiffs allege defendants violated this section by falsely marking the 3½-inch Cut-N-Seals "patent pending." As with their section 17200 claim, plaintiffs make no argument and cite no evidence to demonstrate that the trial court abused its discretion in concluding that neither restitutionary disgorgement nor an injunction was appropriate under the facts of this case. Again, the issue is waived. (E.g.,Moulton, supra,111 Cal.App.4th at p. 1215;Badie,supra,67 Cal.App.4th at pp. 784-785.)10III. The Trial Court Did Not Abuse Its Discretion by DenyingDefendants' Motion for Attorney Feesfn*We now turn to the cross-appeal filed by defendants Good Things and Ten Mark (collectively, Good Things). They urge that the trial court abused its discretion by denying their motion for attorney fees. Specifically, Good Things asserts that (1) the trial court failed to provide a sufficient explanation for its order denying fees, and (2) the record does not support the trial court's conclusion that plaintiffs' claims were not groundless or unreasonable. Thus, Good Things asks that we vacate the order denying attorney fees and remand for reconsideration. The Lanham Act provides that "[t]he court in exceptional cases may award reasonable attorney fees to the prevailing party." (15 U.S.C. § 1117(a).) The Ninth Circuit has held that this requirement is met when the case is either "groundless, unreasonable, vexatious,orpursued in bad faith.'" (Cairns v. Franklin Mint Co.(9th Cir. 2002)292 F.3d 1139,1156, citingAvery Dennison Corp. v. Sumpton(9th Cir. 1999)189 F.3d 868,881.) We review an order denying attorney fees for an abuse of discretion. (Cairns v. Franklin Mint Co., supra,292 F.3d at p. 1156;Horphag Research Ltd. v. Pellegrini(9th Cir. 2003)337 F.3d 1036, 1040.) Good Things urges first that the order denying fees must be set aside because the trial court failed to provide a detailed statement of the reasons for its ruling. We do not agree that a detailed statement was required. To the contrary, under California law, "[a] statement of decisionis not requiredregarding an award of attorney fees pursuant to a motion." (Maughan v. Google Technology, Inc.(2006)143 Cal.App.4th 1242,1252, emphasis added; see alsoMaria P. v.Riles(1987)43 Cal.3d 1281,1294["we have discovered no case requiring a statement of decision for an order on a motion for attorney fees"].) Thus, the trial court's failure to provide a detailed statement of reasons is not a ground for reversing the order denying Good Things' fee motion. CitingMattel Inc. v. Walking MountainProductions(9th Cir. 2003)353 F.3d 792, Good Things urges that a different standard applies to fee motions under the Lanham Act. Again, we do not agree. Good Things is correct thatMattelrequires explicit findings when a court issues an order denying attorney fees, but it does so pursuant to Federal Rules of Civil Procedure, rule52(a), which requires that the court "shall find the facts specially and state separately its conclusions of law'" on motions for attorney fees. (Id.at p. 815, fn. 23, quoting Fed.R.Civ.Proc., rule52(a).) Rule 52(a), like all of the Federal Rules of Civil Procedure, is "of course, not binding on our state courts." (Saidi-Tabatabai v. Superior Court(1967) 253 Cal.App.2d 257, 266; see alsoCounty of Los Angeles v. Superior Court(2006)139 Cal.App.4th 8,17["Although federal law controls the substantive aspects of plaintiffs' federal civil rights claim, state rules of evidence and procedure apply unless application of those rules would affect plaintiffs' substantive federal rights"];Bradt v. Smith(5th Cir. 1981)634 F.2d 796,799["[T]he Federal Rules of Civil Procedure . . . do not, however, govern practice and procedure before the courts of the several states"];Washington-Baltimore Newspaper Guild, Local 35 v. Washington Post Co.(D.C. Cir. 1971)442 F.2d 1234,1239[Federal Rules of Civil Procedure were "[n]ever designed to apply to proceedings in other than the United States District Courts"].) Thus, the trial court's failure to provide a detailed statement of its reasons for denying Good Things' fee motion does not compel reversal. Good Things also contends that the fee order must be reversed because the record does not support the trial court's conclusion that plaintiffs' claims were not groundless or unreasonable. The argument is unavailing. Even if we were to find, as Good Things urges, that the present case is "exceptional," that finding would not require us to conclude that the denial of fees was an abuse of discretion. As we have noted,15 United States Code section 1117(a) provides that in exceptional cases, the court "may" award reasonable attorney fees to the prevailing party. "The may' has been generally considered as making the award discretionary even if it fits within the statutory standard of an exceptional circumstance." (International Olympic Committee v. SanFrancisco Arts Athletics(9th Cir. 1986)781 F.2d 733,738; see alsoDieter v. B H Industries ofSouthwest Florida, Inc.(11th Cir. 1989)880 F.2d 322,329["Even if the trial court finds that the circumstances of the case are, in fact, exceptional, the decision whether to award attorney's fees is still discretionary"];Jellibeans, Inc. v. SkatingClubs of Georgia, Inc.(11th Cir. 1983)716 F.2d 833,846-847["Even if the court determines the case to be exceptional, the decision to award attorney fees is still within the court's discretion"].) Because the court need not award attorney fees even in an exceptional case, we cannot conclude that the trial court's failure to do so in this case was an abuse of discretion. Accordingly, we affirm the denial of attorney fees.Page 1168
DISPOSITION
For the foregoing reasons, we (1) affirm the judgment for defendants, and (2) affirm the order denying Good Things International and Ten Mark Corporation's motions for attorney fees. Defendants shall recover their costs on appeal.

Epstein, P. J., and Willhite, J., concurred.

A petition for a rehearing was denied August 20, 2007.Page 1169

  2. The court also addressed defendants' alternative claim that plaintiffs lacked standing to assert the third, fourth, and eighth causes of action. The court found that: (1) the undisputed evidence demonstrated that Magic Kitchen did not acquire any assets, rights, or claims from Kitchen Connection and, therefore, it lacked standing to assert claims against the defendants, and (2) the undisputed evidence demonstrated that Kaiser had no interest in her personal capacity in any cause of action because all rights to the Tartmaster were held by the Kitchen Connection. The court initially found that Kitchen Connection also lacked standing, but it later reversed itself and, thus, denied the motion for nonsuit or directed verdict on the ground of lack of standing. ↩
  3. `To establish trade dress infringement, [a plaintiff] must show (1) that its product design is non-functional, (2) that the design is inherently distinctive or has acquired a secondary meaning, and (3) that there is a likelihood of confusion. [Citation.] Because affording trade dress protection to product designs may hinder legitimate competition, the Ninth Circuit has advised district courts to evaluate such claims with greater scrutiny than claims involving other forms of trade dress." (Continental Laboratory Products, Inc. v. Medax Intern., Inc., supra,114 F.Supp.2d at p. 997; see alsoRoulo, supra,886 F.2d at p. 935.) ↩
  4. Plaintiffs contend that the state law claim most analogous to their federal trade dress infringement claim is for unfair practices under section 17200. Thus, they contend that the applicable statute of limitations is four years. (Bus. Prof. Code, §17208.) Defendants disagree, urging that the three-year statute of limitations for fraud and mistake claims applies. (Code Civ. Proc., §338, subd. (d).) We need not resolve this question because, as we discuss below, plaintiffs filed this action more than four years after they learned of the allegedly infringing conduct. Thus, whether the statute of limitations is three years or four years is not material to resolving this appeal. ↩
  5. This version of the opinion amended and superseded the earlier version cited by plaintiffs, which was published atGrand Canyon Trustv. Tucson Elec. Power Co.(2004)382 F.3d 1016. ↩
  6. According to the Ninth Circuit, this principle "appears to be based on the equitable maxim that `he who comes into equity must come with clean hands,'Hermes Intern, v.Lederer de Paris Fifth Ave.219 F.3d 104,107(2d Cir. 2000) (quotingPrecision Instrument Mfg. Co. v. Auto.Maint. Mach. Co.,324 U.S. 806,814[89 L.Ed. 1381, 65 S.Ct. 993] (1945)), and entered the legal landscape in the form of a musing by Judge Learned Hand, as a caveat to his famous articulation of the laches doctrine . . .: `It must be obvious to every one familiar with equitable principles that it is inequitable for the owner of a copyright, with full notice of an intended infringement, to stand inactive while the proposed infringer spends large sums of money in its exploitation, and to intervene only when his speculation has proved a success. Delay under such circumstances allows the owner to speculate without risk with the other's money; he cannot possibly lose, and he may win.If the defendantbe a deliberate pirate, this consideration might be irrelevant.. . .'" (Danjaq LLC, supra,263 F.3d at pp. 956-957, quotingHaas v. Leo Feist,Inc.(S.D.N. Y. 1916) 234 F. 105, 108.) ↩
  7. Plaintiffs also assert that the trial court erroneously excluded evidence that Pampered Chef assigned the Cut-N-Seal trademark to Berkshire Hathaway, Inc., which in turn assigned it to Columbia Insurance Co. Neither the trial record nor plaintiffs' appellate briefs suggest why this evidence was relevant to plaintiffs' case, and thus we cannot conclude that its exclusion was an abuse of discretion. (Austin B. v.Escondido Union School Dist.(2007)149 Cal.App.4th 860,885[57 Cal.Rptr.3d 454] [trial court's decision to admit or exclude evidence under the abuse of discretion standard];City of Ripon v. Sweetin(2002)100 Cal.App.4th 887,900[122 Cal.Rptr.2d 802] [same].) Moreover, even if the exclusion were erroneous, it would be grounds for reversal only if there is a reasonable probability that a result more favorable to plaintiffs would have been reached in the absence of the error. (Robertsonv. Fleetwood Travel Trailers of California, Inc.(2006)144 Cal.App.4th 785,815[50 Cal.Rptr.3d 731], citingPeople v.Watson(1956) 46 Cal.2d 818, 836 [299 P.2d 243].) Plaintiffs have not made such a showing. ↩

  9. We note that, although the trial court gave a detailed oral explanation from the bench of his reasons for granting judgment for defendants, apparently no statement of decision was requested or rendered. Thus, we will imply all findings necessary to support the judgment, so long as those findings are supported by substantial evidence. (McLaughlin v. Walnut Properties, Inc.(2004)119 Cal.App.4th 293,302;In re Marriage of Condon(1998)62 Cal.App.4th 533,549, fn. 11.) ↩
  10. Moreover, it appears on the present record that plaintiffs lack standing to pursue this claim. Although previously any person acting for the general public could file suit for violations of section 17200, "Proposition 64, approved by the voters on November 2, 2004, changed all that. Proposition 64 amended the UCL so that a private person has standing to sue only if he or she "has suffered injury in fact and has lost money or property as a result of such unfair competition." (CryoportSystems v. CNA Ins. Companies(2007)149 Cal.App.4th 627,630, citingCalifornians for Disability Rights v. Mervyn's, LLC(2006)39 Cal.4th 223,227; see § 17204.) This amendment, codified in section17204of the Business and Professions Code, became effective on November 3, 2004, and applies to all pending cases. (Californians for Disability Rights, supra,39 Cal.4th at pp. 227,232-233.) In the present case, plaintiffs have not identified any evidence that defendants' alleged failure to obtain a certificate of qualification has caused them to suffer "injury in fact" or to "lo[se] money or property," nor has our independent review of the record revealed any such evidence. ↩
  11. As discussed above, plaintiffs also appear to lack standing to assert this claim. (See fn. 8, ante.) ↩
  12. Further, as with section 17200, a person may pursue a section 17500 claim only if he or she "has suffered injury in fact and has lost money or property as a result of a violation of this chapter." (Bus. Prof. Code, §17535.) Because there is no evidence that plaintiffs suffered injury or lost money or property as a result of defendants' alleged false advertising, plaintiffs appear to lack standing to pursue this claim. ↩
