Interference No. 102,622 ABANDONMENT, SUPPRESSION AND CONCEALMENT On June 5, 1992, Rivetti et al. filed notice that they intended to argue that Oates abandoned, suppressed or concealed an actual reduction to practice as required by 37 C.F.R. § 1.632. See Paper Number 41. Nevertheless, "without an actual reduction to practice there is no invention in existence which can be abandoned, suppressed, or concealed." Peeler v. Miller, 535 F.2d at 651, 190 USPQ at 120. Because Oates has not presented any evidence of priority based on an actual reduction to practice, it is Rivetti et al.'s burden to establish by a preponderance of the evidence that Oates abandoned, suppressed or concealed her invention within the meaning of 35 U.S.C. § 102(g). Gallagher v. Smith, 206 F.2d 939, 99 USPQ 132 (CCPA 1953). We agree with Oates for reasons expressed in her reply brief at page 4 thereof that Rivetti et al. have failed to prove that Oates actually reduced to practice an embodiment within the Count at a time prior to Rivetti et al.'s Italian application benefit date of March 4, 1988.
