Apple also filed a second lawsuit against Qualcomm in China accusing it of failing to license "standard essential patents" broadly and inexpensively.
Last week, Apple sued Qualcomm in the USA for $1 billion alleging that the company has been 'charging royalties for technologies they have nothing to do with'. The lawsuit followed one from the FTC which charged Qualcomm with using anticompetitive tactics to maintain its monopoly in the supply of baseband processors used in cellular phones.
Qualcomm has already responded to the Chinese lawsuits with Don Rosenberg, executive vice president and general counsel of Qualcomm saying:
"These filings by Apple's Chinese subsidiary are just part of Apple's efforts to find ways to pay less for Qualcomm's technology. Apple was offered terms consistent with terms accepted by more than one hundred other Chinese companies and refused to even consider them. These terms were consistent with our NDRC Rectification plan. Qualcomm is prepared to defend its business model anywhere in the world. We are proud of our history of contributing our inventions to the development and success of the mobile communications ecosystem."
