The San Diego-based company aims to inflict pain on Apple in the world’s largest market for smartphones and cut off production in a country where most iPhones are made. The product provides almost two-thirds of Apple’s revenue. Qualcomm filed the suits in a Beijing intellectual property court claiming patent infringement and seeking injunctive relief, according to Christine Trimble, a company spokeswoman.
"Apple employs technologies invented by Qualcomm without paying for them," Trimble said.
Qualcomm new lawsuit comes after being slapped with a massive $773 million fine by the Taiwan Fair Trade Commission for antitrust violations. The company is also being investigated by the Korea Fair Trade Commission, the FTC, and the European Commission.
Back in January, Apple sued Qualcomm for allegedly withholding $1 billion in rebates because it complied with Korean regulators investigating Qualcomm. It has since expanded that lawsuit on the heels of a Supreme Court ruling last month, arguing that the license agreements that give Qualcomm a cut of every iPhone manufactured are invalid.
Qualcomm's suit in China is based on three non-standard essential patents that allegedly cover power management and touch-screen technology like Force Touch used in current iPhones. The inventions "are a few examples of the many Qualcomm technologies that Apple uses to improve its devices and increase its profits,” Trimble claims.
