Claim Construction Reversal Requires New Trial

Posted in Claim Construction

Black & Decker, Inc. v. Robert Bosch Tool Corp., No. 2007-1243, 1244, Slip Op. (Fed. Cir. Jan. 7, 2008).*

The Federal Circuit affirmed the Northern District jury’s obviousness verdict, and Judge St. Eve’s denial of defendant’s inequitable conduct claim. But the Federal Circuit reversed the Northern District’s construction of “power conversion circuit” and remanded for further proceedings and, perhaps, a new trial.** The Federal Circuit held that the Northern District relied largely upon claim differentiation for its construction and, in the process, gave the patent scope beyond the disclosed invention.

The Federal Circuit held that the Northern District’s pre-KSR obviousness jury instruction was not reversible because defendants identified no evidence in the record that supported an obviousness finding even under the broader KSR standard.
