After careful experiments, made by the Navy Department, before the patent was granted, a contract was made on March 21, 1892, the material elements of which are these: It recited that the company was the owner of the patented rights to a process "known as the 'Harvey process’ for the treatment of armor plate for use in the construction of vessels;” an agreement that armor plate “treated under the said 'Harvey process’ ” shall be applied to certain vessels; the previous giving of an option to the Navy Department “of purchasing the right to use and employ the ‘Harvey process’ for treating armor plates, as follows.: 'We hereby agree to give to the Navy Department an option for the purchase of the application of the Harvey process for treating armor plates, which was tested at the Naval Ordnance Proving Ground, Annapolis, Mel., February 14, 1891,’ ” on terms set forth, one of which *314 was that Harvey, the inventor, should furnish all details in his possession, or which he might develop in the perfection of his methods; the acceptance of the offer by the Navy Department; and an agreement by the United States to pay the expense of applying “the said process,” etc. The contract th…

  1. Patent Law — Licensee Estoppel A licensee who has contracted to pay royalties for the use of a patented process, with full knowledge of what he was contracting for and having had the benefit of its use, cannot resist payment of the royalty on the plea that the patent is invalid; the licensee is estopped to deny the validity of the patent he has been using. 196 U.S. 310 (Holmes, J.)
  2. Patent Law — Licensee Estoppel — Vendee Versus User The rule estopping a licensee to deny the validity of the patent is not confined to one who has enjoyed the advantage of a practical monopoly as a seller; it applies equally to a mere user of the patented article, since a thing made under a patent supposed to be valid would not have been used or sold but for the license from the patentee. 196 U.S. 310 (Holmes, J.)
  3. Contracts Law — Interpretation A contract provision that payment of royalties shall cease "in case it should at any time be judicially decided" that the licensor is not legally entitled to the exclusive right under the patent is construed according to its literal meaning to require an actual judicial decision to that effect, and is not satisfied by the licensee's present contention that the patent is invalid. 196 U.S. 310 (Holmes, J.)
  4. Contracts Law — Interpretation Where a contract for the use of a process identifies its subject matter by the name known in the trade and in the parties' common speech rather than solely by reference to the patent, the contract covers the process actually used, even if that process varies somewhat from the process described in the patent, because the parties intended the agreement to reach the process actually employed. 196 U.S. 310 (Holmes, J.)
