Text: 3 Kollonitsch's patent application has the effective filing date of June 1, 1977. Bey's patent application has the effective filing date of July 11, 1977. The interference count is for certain irreversible enzyme inhibitors (for pharmaceutical use), including the monofluoromethyl derivatives of ornithine, lysine, and arginine. 1 Bey presented testimony 2 and exhibits in support of his claim to priority; Kollonitsch chose to rely solely on his filing date. 4 NOTE: OPINION CONTAINS TABLE OR OTHER DATA THAT IS NOT VIEWABLE 5 Bey made two arguments before the board. First, he argued that Kollonitsch was not entitled to make his claim correspond to the interference count because Kollonitsch's application did not sufficiently disclose the utility of the invention under 35 U.S.C. Secs. 101, 112. Second, Bey argued that he was entitled to priority because he had prior conception of the invention coupled with reasonable diligence in reducing it to practice. The board held against Bey on both issues, and Bey appealed both issues to this court. We hold that Bey was entitled to priority on the basis of prior conception coupled with diligence; thus, we need not reach the issue whether Kollonitsch's application made a sufficient disclosure.
