Apple in its new countersuit accused Qualcomm of patent infringement and this is part of a long-running dispute between the two business gurus. Earlier, there had been reports that Apple had been in violation of Qualcomm’s battery life patents. This company has dismissed this claims and proceeded to allege that all of Qualcomm’s patents had been invalid.

On Wednesday, Apple scrutinized Qualcomm’s complaint and went ahead to revise the answer it had planned to give. This took place in U.S. District Court situated in San Diego and Apple outlined that Qualcomm violated eight battery life patents under its ownership.

Most of Apple’s patents are quite specific in nature. First and foremost they are about ensuring each of a phone’s processor draws quite little in terms of power required. Secondly, they should be able to turn off parts of the processor during those instances when they are not needed. Lastly, they should be able to enhance the sleep and wake functions.

In Apple’s filing, it made allegations that Qualcomm’s Snapdragon 800 and 820 processors had clearly infringed on the patents. These processors are the ones that usually power phones manufactured by Alphabet’s Google’s Pixel and Samsung Electronics .The surprising bit is that both Google and Samsung were left out in Apple’s counterclaims.

There have been reports that Apple was the first that sought the patents. That was way before Qualcomm even thought about the same. Apple’s official disclosed that the company was determined to obtain damages from San Diego-based Qualcomm.

A person familiar with the matter opined, “Qualcomm filed its patent infringement lawsuit at the same time it filed a complaint with the U.S. International Trade Commission seeking to ban the import of Apple iPhones that use competing Intel chips because of the alleged patent violations.”

One cannot help but wonder for how long the dispute between this two will be going on. Back in January, apple moved ahead to sue Qualcomm over claims that it had withheld about $1 billion in patent royalty rebates from it. After that, Qualcomm proceeded to sue a number of the contract manufacturers working for Apple. However, Apple went on its way to defend them
