Headnotes

  1. Patent Law — First Inventor One is not the first inventor of a thing, within the meaning of the patent statutes, where another has made a complete and adequate disclosure of the thing claimed in a patent application before the earliest date to which the alleged inventor can carry his invention, even though the prior applicant did not claim the thing disclosed and his patent issued only after the later applicant's patent was applied for. 270 U.S. 390, 399
  2. Patent Law — Reduction to Practice For purposes of reduction to practice, a description that would bar a patent if printed in a periodical or in an issued patent is equally effective when contained in a patent application, and the issuance of the patent pursuant to that application makes the described invention public property. 270 U.S. 390, 401
  3. Patent Law — Prior Disclosure as Bar Where a prior applicant had done all he could to make his description public and had taken steps that would make it public as soon as the Patent Office completed its work, the later applicant may not profit from delays in the Patent Office to establish himself as first inventor, and the prior disclosure renders it impossible for the later applicant to claim the invention. 270 U.S. 390, 401
  4. Patent Law — Infringement Under the statutory defense that the patentee was not the original and first inventor, it is not necessary to show who did invent the thing; it is enough to show that the patentee was not the first inventor. 270 U.S. 390, 402
