Apple has filed a lawsuit against Qualcomm in China seeking 1bn yuan (£115m) in damages, claiming the chip maker has abused its market position, Apple has also filed a second case alleging Qualcomm had broken the terms of a deal covering how Apple could use technologies it had licensed.
Qualcomm said it was ready to defend its business practices in court. The lawsuits come soon after US regulators sued Qualcomm, alleging that the firm was guilty of market abuse. In its legal papers, Apple said Qualcomm was using its dominant position as a supplier of communication chips for mobile phones to squeeze more cash from firms that use its technologies.
In a statement, Qualcomm said it had not yet seen all the details of the two cases. "These filings by Apple's Chinese subsidiary are just part of Apple's efforts to find ways to pay less for Qualcomm's technology," said Don Rosenberg, head lawyer for Qualcomm. He added that Apple was offered terms and conditions that were drawn up in 2015 following a ruling by Chinese trade regulators that dictated how Qualcomm should deal with companies keen to use its modem chips.
"Qualcomm is prepared to defend its business model anywhere in the world," said Mr Rosenberg. Qualcomm said it planned to fight both legal cases.
