Appeal No. 1996-2624 Application No. 08/186,352 at the time that appellants made their invention is insufficient to establish the necessary motivation. One of the advantages of Bosse's system is the flexibility of changing the transfer drum speed between transfer stations without having to replace the cam plate [49]. Bosse accomplishes this object by adjusting the attachment point of the coupling member [51] along the longitudinal grove [53] in rocker arm [50]. We fail to understand why one of ordinary skill in the art would have been motivated to surrender this advantage in Bosse's gear system simply because noncircular planetary gear systems were known. Since the examiner's proposed combination of Bosse and Katori would involve a major reconstruction of the Bosse drive system and would appear to destroy certain desirable advantages sought by Bosse, we consider that one of ordinary skill in the art would not have been led by the collective teachings of the applied references to make the modifications of Bosse urged by the examiner. In fact, we view the examiner's position to be based on impermissible hindsight derived from applicants' own disclosure. Accordingly, we will not sustain the standing 35 U.S.C. § 103 rejection of independent claims 1 and 20 based on 12Page: Previous 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 NextLast modified: November 3, 2007
