Appeal No. 96-1837 Application No. 08/083,372 Viewing the examiner’s rejection and rationale therefor in the most favorable light, it is the examiner’s position that Matsudaira discloses the claimed subject matter but for the buffer having a thermal expansion coefficient substantially intermediate the thermal expansion coefficients of the two adjacent members and for the fixing force recited in claims 4 and 7. In order to compensate for these deficiencies, the examiner cites Rajac for a teaching of a buffer having a similar thermal expansion coefficient as the adjacent members and contends that the claimed force range would have been obvious since this amounts to only “routine experimentation and optimization” [principal answer-page 5]. First, with regard to the claimed force range, the range recited requires a particular relationship between the fixing force, the mass of the recording medium, the acceleration acting on the medium and a minimum friction coefficient. The examiner cannot explain such a specific limitation away by merely labeling the requirement “routine experimentation and optimization.” In any event, we never reach the limitations of the dependent claims because, in our view, the examiner’s reasoning with regard to the rejection of the independent claims is flawed. While Rajac teaches the use of a buffer having a similar thermal 4Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
