Brenner, Commissioner of Patents v. Manson

United States Supreme Court
383 U.S. 519 (1966)


Manson (plaintiff) invented a process for making known steroids and filed a patent application claiming the process. However, three years before his filing date, two other inventors had filed their own patent application claiming the same process. Manson provided proof of prior inventorship and sought an interference with those inventors. The examiner denied the request for interference on the basis that Manson’s application failed to disclose utility for the compounds produced by the claimed process. The Patent Office Board of Appeals affirmed the rejection and the Court of Customs and Patent Appeals (CCPA) reversed. Brenner appealed on behalf of the Patent Office.
