Leapfrog Enterprises, Inc. v. Fisher-Price, Inc., No. 06-1402, Slip Op. (Fed. Cir. May 9, 2007).

The Federal Circuit issued its first opinion analyzing an obviousness determination based upon the Supreme Court decision in KSR v. Teleflex, 550 U.S. __, 2007 WL 1237837 (2007).  The Court affirmed the district court’s holding that the claim was invalid based upon obviousness and explained that obviousness is not determined by "a rigid formula disassociated from the consideration of the facts of a case."  You can download a copy of the Federal Circuit’s decision here.
