Interference No. 102,922 Interference No. 103,088 patentability of claims in accordance with 37 CFR § 1.633(b) or 37 CFR § 1.633(c)(4) have been raised in either interference. Gill is senior party in both interferences by virtue of the March 8, 1990, filing date accorded to him in the respective declaration notices. Gill did not take any testimony in either interference to establish a date earlier than the March 8, 1990 date. Therefore, Gill is restricted to his filing date; and Dumas, as junior party, must establish priority by a preponderance of the evidence. Peeler v. Miller, 535 F.2d 647, 651, 190 USPQ 117, 120 (CCPA 1976). For its case on priority, the party Dumas relies upon two alternative grounds: (1) derivation by senior party Gill; and (2)actual reduction to practice before the March 8, 1990 date of senior party Gill. Both parties filed records, briefs and appeared at final3 4 hearing. 3The Dumas and Gill record and exhibits will be referred to herein by DR, DX, GR and GX followed by the appropriate page or exhibit number. 4The Dumas and Gill briefs will be referred to as DB, GB and DRB followed by the appropriate page number. 5Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
