Interference No. 103,446 any other person at Bayer knew in 1986 the nature of the mica filler used in the preparation and testing of the plaques. While Sanns claims to have taken photographs of the mica he allegedly measured, said photographs are not of record in this proceeding. Additionally, nothing in Sanns' testimony or in the record before us, evidences that Sanns appreciated that WG-2 mica had a particle size of less than 1.5 microns or an aspect ratio of greater than 40 as required by Count 1. Indeed, Sanns' memorandum of invention only mentions the mica by its proprietary name "WG-2" and does not satisfy Count 1 with respect to either particle size or aspect ratio. Sanns' notebook page attached to the memorandum of invention only speaks of an aspect ratio of "greater than 20 or 30" and a particle size "smaller than 1/64 inch". In our opinion, Martinez is attempting to prove, nunc pro tunc, that the work performed for Sanns in 1986 and 1988 is transformed via the stipulation of the parties to an actual reduction to practice relating back to the date of the actual work. However, as we have stated above, establishing a reduction to practice, nunc pro tunc, is not possible. 16Page: Previous 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 NextLast modified: November 3, 2007
