Interference No. 103,414 relied upon as evidence of priority actually worked for its intended purpose." Newkirk v. Lulejian, 825 F.2d 1581, 1582, 3 USPQ2d 1793, 1794 (Fed. Cir. 1987). This is so even if the "intended purpose" is not explicitly set forth in the counts of the interference. See, e.g., Elmore v. Schmitt, 278 F.2d 510, 125 USPQ 653 (CCPA 1960); Burns v. Curtis, 172 F.2d 588, 80 USPQ 587 (CCPA 1949). However, the testimony does establish that by October 5, 1992, Unistrut considered the partially tapered rivet to be satisfactory for its intended use (Statement of Facts, ¶ 20). 7 The burden therefore shifts to Henry to prove a date of invention prior to that date. English v. Ausnit, 38 USPQ2d 1625, 1630 (Bd. Pat. App. & Int. 1993)(citing Kwon v. Perkins, 6 USPQ2d 1747, 1752 (Bd. Pat. App. & Int. 1988), aff'd, 866 F.2d 325, 12 USPQ2d 1308 (Fed. Cir. 1989); D'Amico v. Brown, 155 USPQ 534 (Bd. Pat. Int. 1967); and Fisher v. Gardiner, 215 USPQ 620 (Bd. Pat. Int. 1981)). G. Henry's case for priority Although the count under either party's construction is broad enough to encompass the pre-existing rivet, Henry's case for priority fails because the evidence fails to identify, directly or by implication, Henry as the inventor of that rivet. See I Rivise & Caesar, Interference Law & Practice § 112, at p. 323 (Michie Co. 1940) ("a person cannot claim to be the inventor 7 Unistrut's September 29, 1992, expression of satisfaction with this rivet was conditioned on further testing (Statement of Facts, ¶ 15). - 10 -Page: Previous 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 NextLast modified: November 3, 2007
