Interference No. 104,649 Page No. 26 Concepts in Mountain View, California in late December 1993 or early January 1994. (KX 1007, 16 and KX 1008, 14). This removable platen prototype was then shown to Mr. Pieper and successfully tested for him before the end of January 1994. (KX 1008, T 4 and KX 1006, 17). All three declarations state that the prototype device successfully tested in December 1993 or January 1994 is described by Keagy claim 1, whose language is identical to Count 1. (KX 1006, 9, KX 1007,$ 9, and KX 1008,18). The three declarations submitted by Keagy describe the testing of a microprism platen for an electronic fingerprint system. The description of the device that is mentioned in the three declarations is consistent with the description contained as an attachment to a letter from Mr. Keagy to Harold Jackson, Esq. that bears a date of January 31, 1994. (KX 1005). Specifically, the letter indicates that an updated disclosure of the fingerprint platen and fingerprint card reader was being provided to Mr. Jackson. The disclosure describes a platen that employs an optical surface to separate beams used in imaging the fingerprint. Suitable optical surfaces are said to include "small prisms in parallel rows." (KX 1005, Exhibit B, p. 3 of 6). Keagy has filed sufficient and convincing evidence that a reduction to practice occurred in this country for Keagy's claimed invention. This reduction to practice was prior to the effective date of the Chen reference. Accordingly, Chen is not available as a prior art reference to Keagy's claims. Additionally we note that Chen teaches that its microprisms are "elastic" as compared to the "rigid" prismlets recited in Keagy claim 1, Zhou claim I and Caunt 1, _Indeed, Chelm., specifically states that the microprisms become deformed when impressed by a finger.
