Apple countersuit alleges Qualcomm infringed battery life patents for Snapdragon 820, 800


Apple and Qualcomm are battling in court right now over alleged patent infringement.

Coming back to the latest lawsuit, Qualcomm's claims that Apple violates patents related to memory design, power management, RF transceivers, etc.

Apple has accused supplier Qualcomm of behaving like a "common patent troll", as the iPhone maker responds to the mobile chip designer with another round of litigation. Yes, it really looks like Qualcomm is going after the iPhone X, iPhone 8, and iPhone 7.

The latest move from Qualcomm can also be seen as a response to Apple's filing of new cases against the former. Earlier this August, the Snapdragon creator raised issue with six patent violations that led to an investigation, but nothing else thus far.

Qualcomm had bought several Palm patent from IT giant HP (Hewlett-Packard) in 2014.

In the amended filing on Wednesday, Apple wrote that Qualcomm asserts "weak patents that nibble at the edges of the smartphone platform and cover concepts that Apple simply does not use". Qualcomm General Counsel Don Rosenberg noted, "You can't react that quickly to file lawsuits".

On Thursday, just hours after Apple filed a suit alleging that Qualcomm's Snapdragon chips infringe on eight of its battery patents, the tit-for-tat battle stepped up a notch with the launch of three new lawsuits. The Cupertino company said its patents in question ensure that the processor uses only minimal power and turns off the parts that are not needed to save battery.

The Snapdragon 800 and Snapdragon 820 smartphone processors are previous generation chips used to power mostly Android smartphones made by companies such as LG, Sony and Samsung.

In the filing Wednesday, Apple says its work on power management technology pre-dates the iPhone and includes innovations borne out on general objective computers.

Qualcomm alleged the infringement took place in a range of Apple devices.

The first complaint accused Apple of infringing United States patent numbers 8,683,362; 8,497,928; 7,844,037; and 9,203,940, relating to a range of technologies including those which allow multiple apps to run at once, camera focusing techniques and methods of responding to incoming calls and texts. The total number of iPhones sold during the given period was much higher considering Rosenblatt's numbers don't include the iPhone 8 series and the iPhone 7 series.
