need not suggest solving the same problem set forth by appellant. In re Dillon, 919 F.2d

Appellant’s position at the bottom of page 6 of the brief that there is no incentive to
combine the references of record is misplaced. The top of page 7 of the translation
indicates that a feedback circuit for SQUID assemblies was known in the art but Yokozawa
chose not to utilize it. Each of the secondary references relied upon by the examiner
confirm the desirability and the features of claim 12 on appeal argued to be advantageous
over Yokozawa’s approach. The claimed analog feedback means is stated to be based
upon a negative feedback approach to provide a substantially linear dynamic range for the
bandwidth. Page 186 of Welker article just below the depiction of the overall circuit in
Figure 2 indicates that the depicted feedback loop is used to linearize the system. Its
depiction in Figure 2 suggests a negative feedback approach. As to Fujimaki, even the
brief abstract associated with this reference indicates that the feedback loop 21 in the
various figures provides negative feedback. The translation of page 10 of this reference
indicates that when the feedback loop 21 is utilized the upper limit of the dynamic range
disappears suggesting a more linear and broader dynamic range as claimed. A similar
statement is found in the translation at the top of page 11. Finally, even Biedermann’s brief
abstract shows and states that a negative or degenerative feedback resistor 7 is utilized to
