Wireless chipmaker Broadcom won a patent battle on Wednesday, as a U.S. appeals court affirmed that Qualcomm Inc infringed two patents used to make some of the world's most sophisticated cell phones and upheld an injunction. The U.S. Court of Appeals for the Federal Circuit ruled in Qualcomm's favor on Wednesday in one of the three patents at issue, technology used in video compression in cell phones. It ruled that the patent was invalid and, thus, not infringed.

The two companies are in talks to settle patent battles now being fought in California, the International Trade Commission and in the federal appeals court.

The lawsuit was originally filed in 2005 in Santa Ana, California.

"The Santa Ana case is one of several cases in which Broadcom continues to pursue claims against Qualcomm regarding patent infringement, anti-competitive behavior and fraud issues," Broadcom said in a press statement. "Qualcomm has either lost or withdrawn all of the patent infringement cases it brought against Broadcom."
