Interference No. 103,675 adequate corroboration and because every element of conception must be corroborated11, Chen et al. have no evidence which proves "the formation, in the mind of the inventor of a definite and permanent idea of the complete and operative invention, as it is thereafter to be applied in practice." Coleman, 754 F.2d at 359, 224 USPQ at 862. The section of Chen et al.'s brief devoted to the "reasonable diligence" aspect of their priority case is little more than various conclusions made without regard to any underlying facts which support the conclusions made by Chen et al. For example, at page 174 of their brief, Chen et al. conclude that: The record also shows that Chen meets the second criterion, that reasonable diligence was exercised by Chen from a time prior to December 9, 1992, to a later actual or constructive reduction to practice. In particular, Chen was actively prosecuting the Chen parent applications from prior to December 9, 1992, up through the March 11, 1993, filing date of the Chen patent claiming priority under 35 U.S.C. § 120 to the Chen parent applications. That filing is, by definition, a constructive reduction to practice of the counts. 11 Coleman v. Dines, 754 F.2d 353, 359-60, 224 USPQ 857, 862 (Fed.
