OSRAM Sylvania, Inc. v. Am. Induction Techs., Inc., No. 12-1091 (Fed. Cir. 2012)Annotate this Case
OSRAM’s patent claims a closed-loop tubular electrodeless lamp, having certain and specific discharge current and pressure parameters. The invention generally relates to “a low pressure, high intensity fluorescent light source that can produce considerably more light per unit length than conventional electroded fluorescent lamps.” Electrodeless fluorescent lamps were first disclosed in several patents issued to and articles authored in the 1960s and 1970s. The district court entered summary judgment of invalidity on certain claims. The Federal Circuit reversed, holding that genuine issues of material fact that preclude a finding of anticipation and obviousness on summary judgment and that the district court erred in failing to consider objective indicia of nonobviousness.
