How later courts describe this case

  • noting that the patentee has “the duty of alleging and the burden of proving” compliance with the marking statute
  • “Marking the articles, or notice to the infringers, is made by the statute a prerequisite to the patentee’s right to recover damages against them.”
  • addressing predecessor to Section 287(a) with identical language, requiring that the patentee give notice “to the particular defendants by informing them of his patent and their infringement of it”
  • construing a predecessor statute to section 287, the Court noted that the “clear meaning” of the notification requirement is that a patentee cannot recover damages absent marking or notice to the “particular defendants by informing them of his patent and of their infringement of it.”
  • requiring a pleading equivalent to “with a knowledge of the patent and of his infringement [ ]” and “holding the patentee to allege . . . notice to the public or to the defendant, from which such knowledge must necessarily be inferred” (internal quotation marks omitted)
  • requiring a pleading equivalent to “with a knowledge of the patent and of his infringement [ ]” and “holding the patentee to allege . . . notice to the public or to the defendant, from which such knowledge must necessarily be 4 inferred” (internal quotation marks omitted)
  • “[T]he duty of alleging, and the burden of proving, either [actual notice or constructive notice] is upon the [patentee].”
  • a patentee has "the duty of alleging and the burden of proving” compliance with § 287(a)

Headnotes

  1. Patent Law — Damages A patentee or assignee who makes or sells the patented article cannot recover damages against infringers unless he has given notice of his right either to the whole public by marking the article "patented" or to the particular defendants by informing them of his patent and of their infringement. 152 U.S. at 247–48
  2. Patent Law — Burden of Pleading and Proof Marking the patented articles and notice to infringers are affirmative facts to be done by the patentee, and, because marking is a matter peculiarly within his own knowledge and the statute expressly places the burden of proving notice on him where the articles are unmarked, the duty of alleging and the burden of proving either fact rest upon the plaintiff. 152 U.S. at 248
  3. Patent Law — Infringement A patentee who has neither marked his goods as required by statute nor proved notice to the infringers cannot recover damages, notwithstanding an allegation of notice in the bill that is denied in the answer and unsupported by proof. 152 U.S. at 248
  4. Patent Law — Infringement To charge a manufacturer or seller under the design patent act of February 4, 1887, the defendant must have applied or sold the patented design "knowing that the same has been so applied," which is equivalent to acting with knowledge of the patent and of his infringement; the patentee must allege and prove such knowledge, or else a notice to the public or to the defendant from which that knowledge must necessarily be inferred. 152 U.S. at 248–49
  5. Patent Law — Waiver of Notice Objection The objection that a patentee failed to prove marking or notice is waived where neither the pleadings nor the answer raised the issue and the defendants first took the objection at a later hearing before a master, rather than at the original hearing. 152 U.S. at 249–50
