Qualcomm confirmed on Friday it had sued Apple in China in an attempt to stop the production and sale of iPhone smartphones in the world's largest market.
The US chip maker filed a suit at the Beijing Intellectual Property Rights Court, claiming Apple was violating patents for it, and was seeking reparations, a company spokeswoman said, but gave no further details.
For its part, Apple said it always wants to pay fair and reasonable royalties for the patents it uses. "During the many years of negotiations with Qualcomm, these patents have not been discussed or actually granted in the last few months," she said.
Qualcomm's move comes in response to Apple's legal battle over the world. The latter has sued Qualcomm for asking for more than royalties and refuses to pay about one billion US dollars in promised rebates.
The new lawsuit in China's second-largest telecoms firm, Colomcom, is aimed at banning iPhone sales. A similar suit was filed last July in the United States. The lawsuit dealt with six patents Apple said were infringing.
Also in Beijing, Apple filed a suit in January against Qualcomm, alleging that its citizen misused its influence in the chip industry and sought one billion yuan ($ 145.32 million) in damages, according to the Beijing Intellectual Property Court.
