X2Y Attenuators, LLC v. Int'l Trade Comm'n , No. 13-1340 (Fed. Cir. 2014)
Annotate this CaseThe International Trade Commission (ITC) determined that Intel did not violate 19 U.S.C. 1337 because Intel’s products were not covered by X2Y’s asserted patents. The patents disclose technology relating to structures for reducing electromagnetic interference in electrical circuits. The inventions use shielding electrodes to reduce the undesirable buildup of charge, known as “parasitic capacitance,” between electrodes used for conduction. In particular, the patents disclose alternating arrangements of shielded and shielding electrodes. The Federal Circuit affirmed. In light of clear disavowals, the claims at issue are limited to “a common conductive pathway electrode positioned between paired electromagnetically opposite conductors.” Because X2Y conceded noninfringement based on that construction, the court did not reach any other issues.
