The U.S. 9th Circuit Court of Appeals has declined to reconsider an August ruling that Qualcomm’s business practices are legal under anti-monopoly laws — likely ending a three-year legal battle between federal regulators and the San Diego company. The court on Wednesday denied a request by the U.S. Federal Trade Commission seeking a second look at a three-judge panel’s decision that threw out the FTC antitrust case. The FTC petition for “en banc” reconsideration was based on alleged legal errors in the panel’s findings, which the agency argued “tears at the fabric of antitrust law.” With an en banc review, a larger group of 9th Circuit judges rehears the case.
