Interference No. 104,290 Edwards based on lack of descriptive support under 35 U.S.C. § 112, first paragraph. Since Edwards' only claim in the interference had been determined to be unpatentable to Edwards, the panel first ruled that junior party LeVeen need not put on a priority case. The panel subsequently modified its ruling and required junior party to prove priority, because, notwithstanding the lack of written description for Edwards' claim, the Edwards specifica tion still appears to be a constructive reduction to practice of at least one embodiment falling within the scope of the count. In this new order, 6 Edwards was permitted to argue abandonment, suppression, or concealment at final hearing, to attack LeVeen's evidence of conception, reduction to practice, and diligence, and to introduce rebuttal evidence. Issues The following issues are raised by the parties in their briefs: a) has junior party LeVeen established an actual reduction to practice before the effective filing date of the Paper No. 2ý0. 5Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
