Interference No. 104,190 As noted above, it is our determination that the December, 1991 work by Rydell was not a reduction to practice of the subject matter of the interference. Additionally, we have determined that if the work by Rydell can be considered to have been a reduction to practice, the junior party has not provided evidence to rebut the inference of abandonment, suppression or concealment raised by the substantial time period between the reduction to practice and the filing of the benefit application. The Parins reply brief has a section discussing supposed public policy principles and equity. It must be noted that Slater as senior party does not have any burden of proof, at least until Parins can overcome Slater’s effective filing date. Unless Parins can overcome the effective filing date, any action or inaction by Slater is simply immaterial. Slater has nothing to prove.
