Apple Inc. sued Qualcomm Inc. in a U.K. patent court, adding to lawsuits across the globe in a sprawling battle over patents and licensing fees between the iPhone maker and the largest maker of mobile phone chips.
The lawsuit was filed Thursday and cites a claim on patents and registered designs. Court records don’t give further details on the patents involved or the company’s arguments.
Apple is separately suing Qualcomm in California, accusing it of monopolizing the market for chips for wireless devices and withholding $1 billion in retaliation for cooperating with South Korean antitrust authorities.
The lawsuits add to a U.S. Federal Trade Commission antitrust suit against Qualcomm and investigations by the European Union and Taiwan. South Korea fined the company 1.03 trillion won ($902 million) in December over practices it said were monopolistic.
At the heart of the U.S. dispute between Apple and Qualcomm is a push by phone makers with the support of regulators to reduce the patent royalties Qualcomm charges. Qualcomm gets the bulk of its revenue from selling chips, but more than half of its profit from the separate licensing business.
The U.K. case is: Apple Retail UK v. Qualcomm, HP-2017-000015, High Court of Justice Chancery Division.
