Interference No. 102,755 While conception of the invention by oral testimony of the inventor unsupported by contemporaneous documents is permitted (Sabo v. Neu and Wilhelm, 148 U.S.P.Q. 378 (Bd. Pat. Interf. 1964)), the absence of documentation as to Nedelk is contrasted to the presence of documentation as to Gillespie, an[] employee with the same company for the same invention at the same time. [SMB 10.] This argument is unpersuasive because documentary corroboration, though preferred, is not required. See Reese v. Hurst, 661 F.2d 1222, 1225, 211 USPQ 936, 940 (CCPA 1981) (independent corroboration may consist of testimony of a witness, other than the inventor, or it may consist of surrounding facts and circumstances independent of information received from the inventor). Turning now to the evidence, Boeing invited representatives of Goodyear Aerospace Corporation (GAC), one of the two predecessor corporations to Aircraft Braking Systems Corporation (ABSC), to Seattle to discuss a problem13 it was experiencing with the Dunlop carbon brakes that were in use on the Boeing 757. As explained in John Nedelk's April In 1987, GAC was purchased by Loral Corporation and became13 one of its four divisions (Milliken, NR 187:21 to 188:16). Beginning in April 1988, these four divisions were converted into four separate companies, including ABSC (Milliken, NR 188:21-22). - 10 -Page: Previous 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 NextLast modified: November 3, 2007
