Apple has alleged that Qualcomm’s Snapdragon chipset is infringing on its battery life patents, in the latest installment of the two companies’ ongoing legal feud.
Apple says Qualcomm is infringing on eight battery life patents, singling out the Snapdragon 800 and 820, which are a few generations behind Qualcomm’s current 835 flagship, but still used for in-market devices such as the Samsung Galaxy S7 and BlackBerry DTEK60.
The patents cover power-saving technologies for processors and a method for quickly increasing and decreasing power usage.
The allegations are in retaliation to Qualcomm’s claims that Apple is in violation of six of its own battery patents.
In its filing of these patent infringement claims, Apple asserted Qualcomm acted “much like a common patent troll” in allegedly selectively picking up patents that might be in Apple’s devices.
Apple and Qualcomm’s larger legal feud began when Apple in January 2017, when Apple sued Qualcomm for roughly $1 billion USD, asserting the company has been “charging royalties for technologies they have nothing do with” — a charge that came shortly after a charge from the U.S. Federal Trade Commission.
Qualcomm then hit back with charges that Apple was withholding payments and violating patents, setting off a long string of legal back-and-forth that is currently ongoing.
