Apple employs technologies invented by Qualcomm without paying for them,
Qualcomm spokesperson Christine Trimble says.
Apple started the legal fight at the beginning of 2017 with a $1 billion lawsuit alleging that Qualcomm demanded license royalties for technologies they have nothing to do with,Qualcomm fired back with its own suit in April, and Apple subsequently began withholding payments to manufacturers of iPhones, which hit the multinational chipmaker so hard that it had to drop its Q3 2017 revenue estimate by half a billion dollars.
In July, Qualcomm escalated the dispute by filing a complaint with the US International Trade Commission requesting they ban the import of the “illegal” iPhones into America. A month later, the ITC started looking into their patent fight.
The latest lawsuits Qualcomm filed in Beijing reportedly cover three non-standard essential patents. They were filed on September 29th and still have not been made public.
Qualcomm is an American multinational semiconductor and telecommunications equipment company that designs and markets wireless telecommunications products and services. It derives most of its revenue from chip making and the bulk of its profit from patent licensing businesses.
