ACS Hosp. System., Inc. v. Montefiore Hosp., 732 F.2d 1572,

the examiner are an
essential part of complying with the burden of presenting a
prima facie case of obviousness. Note In Re Oetiker, 977 F.2d
1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992).
Furthermore, the Federal Circuit states that “[the] mere
fact that the prior art may be modified in the manner
suggested by the Examiner does not make the modification
obvious unless the prior art suggested the desirability of the
modification.”
