Apple Counters Qualcomm with Patent Lawsuit of Its Own

The company also called Qualcomm's lawsuit "a blatant effort to take credit for the innovation of others".

"Apple can import iPhones (regardless of who supplies the modems) that do not infringe the patents asserted in this action, but Apple has no inherent right to infringe Qualcomm's [non-standards essential patents] through the sale of its iPhones", Qualcomm said in its filing.

It's been a quiet couple of weeks for Qualcomm and Apple, so we really should have expected another chapter in the courtroom tale.

The Apple law suit comes after Qualcomm sued it last July for using elements of its battery life patents.

Apple, of course, said it did no such thing and labelled the patents invalid anyway. Two of those were related to Qualcomm's Snapdragon 800 and 820 processors, which powered Samsung phones and Google Pixel phones. More specifically, the patent covers how a processor can minimize power draw by turning off certain functions when not in use, along with enhanced sleep/wake functionality in mobile chips.

This is of course a countersuit, dating back to a lawsuit Qualcomm filed against Apple on exactly the same grounds.

Qualcomm Inc. filed three patent lawsuits against Apple California federal court Wednesday, opening fresh battles in a legal war with allegations that the rival company has violated 16 patents covering technology ranging from camera phones to touchscreen displays. Companies like Apple have this routine of filing and receiving technology patents but that is only there is to it. In a related suit, Qualcomm sued the contract manufacturers that make Apple's phones, but Apple joined in to defend them. Apple emailed Qualcomm to request "highly confidential" information about how its chips work on an unidentified wireless carrier's network, Qualcomm alleged, but Apple had copied an Intel engineer in the email for information.
