Interference No. 101,981 Count 1 by March 2, 1987.

Beyers’ Case For Priority We have reviewed the issues (BaI5) regarding Beyers’ conception and find that Beyers cannot establish a date of conception prior to Batlogg’s date of constructive reduction to practice. Beyers alleges a date of conception that is not earlier than any date Batlogg alleges for their conception or reduction to practice, actual or constructive.
