Terlep v. Brinkmann

Terlep sued Brinkmann, Home Depot and Wal-mart for infringing his patent relating to using omni-directional light emitting diode lamps. The C.A.F.C., quoting Phillips, said '[t]he specification is always highly relevant to the claim construction analysis. Usually, it is dispositive; it is the single best guide to the meaning of a disputed term,' and refused to construe the claim term 'clear' expansively.
