To make Figure 8.41 read on this language in claim 6, it would require a complete reorganization of the circuit elements of the circuit of Figure 8.41 so that it would not [sic, no] longer perform its emitter follower function. There is no teaching in Eden to do this. We agree with appellants. The obviousness rejection of claims 6 and 14 is reversed. Turning next to claims 7 and 15, the examiner contends (Answer, pages 4 and 5) that “[i]t would have been obvious to one of ordinary skill in the art, at the time of the invention, to have substituted Sedra et al.’s single diode with a ‘bipolar transistor ... with its collector and emitter shorted’ as such a substitution provides more current to the load and hence a faster switching speed.” Appellants argue (Brief, page 10) that the claimed bipolar transistor forward biased at its collector-base junction, and shorted at its collector and emitter would not have 5Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
