In the latest development in the continuing legal battle between Apple and Qualcomm, Apple has fired the latest shot by countersuing Qualcomm citing patent infringement.
According to Reuters, Apple has filed a countersuit against Qualcomm claiming its Snapdragon mobile phone chips found in many Android devices infringe upon its patents. The suit, filed at the U.S. District Court in San Diego, specifically claims Apple owns eight battery life patents that Qualcomm is currently using in some chips. Some of these patents ensure that the chip draws only a specific amount of power while in use and turns off parts of the processor when they are not in use.
Two of the processors Apple claims use these patents are the Snapdragon 800 and 820 processors. Samsung Galaxy and Google Pixel phones are among the devices that used these specific processors, but neither of those companies are named in the lawsuit.
Qualcomm is no stranger to legal battles. It has been embroiled in legal battles for many years now over alleged anticompetitive practices with multiple countries’ regulators, including the U.S. Federal Trade Commission.
Earlier this year, Apple sued Qualcomm for $1 billion over unfair royalty charges and jumpstarted the bitter legal battle. Qualcomm responded in kind with a lawsuit of its own with a few other back and forth exchanges that ultimately led to this latest countersuit from Apple.
