Apple Inc. filed suit against Qualcomm Inc. on March 2 in the United Kingdom, Bloomberg News reported.

Details of the lawsuit were scant. The Bloomberg account said Apple’s lawsuit cites a claim on patents and registered designs. Court records did not give further details on the patents involved or the company’s arguments, Bloomberg said. Qualcomm (Nasdaq: QCOM) did not respond immediately to a request for comment.

Apple (Nasdaq: AAPL) is seeking approximately $1 billion from Qualcomm in a suit filed Jan. 20 in U.S. District Court in San Diego. The federal lawsuit seeks rebates that Apple says were promised to the company, and it questions whether Apple should pay Qualcomm the amount of royalties it pays on certain intellectual property. A few days later, Qualcomm announced that Apple had filed suit against the company in China. “Qualcomm is prepared to defend its business model anywhere in the world,” Qualcomm general counsel Don Rosenberg said in the Jan. 25 statement about the Chinese lawsuits.
