Broadcom Corp. v. Qualcom Inc.

Qualcomm Incorporated (“Qualcomm”) appeals from a jury’s determination that Qualcomm infringed U.S. Patents No. 6,847,686 (“the ’686 patent”), No. 5,657,317 (“the ’317 patent”), and No. 6,389,010 (“the ’010 patent”), owned by Broadcom Corporation (“Broadcom”). Qualcomm also appeals from the district court’s issuance of a permanent injunction against Qualcomm. Because the district court erred in its construction of claim 3 of the ’686 patent, we reverse the jury’s determination of infringement of that patent and conclude that claim 3, as properly construed, is invalid. Because the district court did not err in construing the claims of the ’317 patent, and because substantial evidence supports the jury’s determinations of infringement and validity of the ’317 and ’010 patents, we affirm the judgment of infringement of the ’317 and ’010 patents, and the injunction as it pertains to those patents.
