Appeal No. 1997-3172 Application 08/045,989 sputtering source such as that in appellants’ figure 27A were used in Flint’s apparatus, it does not appear that Flint’s shields around the outside of the sputtering source would shield the substrate in front of the sputtering source from oblique deposition emanating from the central portion of the target.2 The examiner argues that “figure 2 of Flint also indicates that oblique deposition is prevented by the shield since only perpendicular particles shown by the arrows are deposited onto the substrate 26” (answer, page 7). Flint, however, provides no teaching that the arrows represent particle travel which is perpendicular to the substrate, but, rather, appears to merely indicate that the direction of travel is from the sputtering sources toward the substrate. The examiner’s interpretation of the reference, in this regard, is based purely on hindsight from appellants’ disclosure, which is improper. See W.L. Gore & Associates v. Garlock, Inc., 721 F.2d 1540, 1553, 220 USPQ 303, 312-13 (Fed. 2 Appellants use shield extension 2231 to provide such shielding (page 56, lines 21-23; figures 23 and 27A). 6Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
