Boss Control v. Bombardier and Sports Cars, Inc. (Fed. Cir. 2005).
In a dispute over a power interrupter, the CAFC affirmed a summary judgment of noninfringement, finding that the patentee had given a special limiting definition to a disputed claim term during prosecution.
Specifically, the court looked to how the patentee had distinguished the invention from prior art and incorporated that distinguishing feature into the claim language.
