Apple's foreign lawsuits against Qualcomm can proceed while the company's dispute plays out in the United States, a U.S. federal judge in San Diego ruled Sept. 7.
Qualcomm and Apple are facing off in federal court over Qualcomm's licensing for modem chips, which provide mobile data connectivity to devices like the iPhone.
Because those chips have become a standard across the mobile phone industry, Qualcomm is required to license them on fair terms.
Apple has alleged that Qualcomm is charging unfair prices for the technology and is engaging in anticompetitive practices. Qualcomm, for its part, has said that it provided fair terms for the parts of technology where it is obligated to do so and that it is within its rights to determine pricing on patents that are not bound by the standards rules.
Qualcomm had sought what is known as an "anti-suit" injunction against Apple, seeking to temporarily halt 11 separate lawsuits against Qualcomm and its subsidiaries in the United Kingdom, Japan, China and Taiwan over many of the same pricing and practices issues as the U.S. case.
But Judge Gonzalo Curiel ruled against Qualcomm and said Apple could proceed with those actions while the U.S. case plays out.
Christine Trimble, vice president of public affairs at Qualcomm, said in a statement, "While we are disappointed by today's rulings, we recognize that the motions involved high procedural hurdles."
Apple praised the ruling.
Qualcomm has also brought an action against Apple before the U.S. International Trade Commission seeking to ban imports of some iPhones. Qualcomm filed a separate civil lawsuit accusing Apple of infringing the patents at issue in that action.
Qualcomm also faces an antitrust complaint from the U.S. Federal Trade Commission. Meantime, four of Apple's contract manufacturers sued Qualcomm on antitrust allegations, and Apple joined that lawsuit.
