Appeal No. 2002-1609 Application 09/129,238 F.2d 1029, 1035, 206 USPQ 289, 296 (CCPA 1980); In re Greenfield, 571 F.2d 1185, 1189, 197 USPQ 227, 230 (CCPA 1978); In re Lindner, 457 F.2d 506, 508, 173 USPQ 356, 358 (CCPA 1972); In re Tiffin, 448 F.2d 791, 792, 171 USPQ 294, 294 (CCPA 1971). In the instant case, appellants’ data fails to meet the burden set out here. We therefore agree with the rejection of claim 14. With respect to claim 21, appellants argue that Fujinaga does not suggest the specific plane anisotropy coefficient range set forth in claim 21. However, on page 8 of the answer, the examiner states that the plane anisotropy coefficient would be inherent since the compositional and process limitations are closely met, absence evidence to the contrary. We note that it is well settled that the Patent Office can require appellants to prove that a function or property relied upon for novelty is not possessed by prior art otherwise meeting the limitations of the claims. In re Best, 562 F.2d 1252, 1255, 195 USPQ 430, 433 (CCPA 1977). Because appellants have not provided such a showing, we agree with the rejection of claim 21. II. Conclusion We sustain the rejection of record. 9Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
