Appeal No. 2001-1209 Application No. 09/106,281 the platen roller speed computing equation, is reduced for temperature ranges above a predetermined value. We don’t necessarily disagree with the Examiner’s assertion (Answer, page 5) that, given Pfeuffer’s disclosed recognition of the relationship between platen roller speed and roller temperature variations, the skilled artisan would find it obvious to derive a mathematical equation to compute the corrected roller speed values. We find no teaching or suggestion, however, in Pfeuffer, or in any of the other prior art of record, that would support the Examiner’s conclusion of the obviousness to the skilled artisan of adjusting the expansion coefficient of the platen roller at temperature ranges above and below a predetermined temperature as claimed. The Examiner must not only make requisite findings, based on the evidence of record, but must also explain the reasoning by which the findings are deemed to support the asserted conclusion. See In re Lee, 277 F.3d 1338, 1343, 61 USPQ2d 1430, 1433-34 (Fed. Cir. 2002). Accordingly, since all of the claimed limitations are not taught or suggested by the applied prior art references, the Examiner’s 35 U.S.C. § 103(a) rejection of claim 5 is not sustained. 11Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
