Apple accuses Qualcomm of patent infringement in countersuit

The legal bickering between Apple and Qualcomm shows no signs of backing down.

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 latest skirmish came Wednesday morning when Apple filed a countersuit to a claim filed by Qualcomm in July alleging that Apple had infringed Qualcomm patents that help extend mobile phone battery life. Qualcomm has stated that Apple violated six of its own patents which also have to do with battery life, and is trying to get the iPhone banned as a result of these infringements.

"Apple's patents are critical to what consumers value in a handset - cutting-edge functionality with superior battery life", said the company in the lawsuit.

As per a report on Reuters, Apple Inc.

Apple at the time denied the claims and said that Qualcomm's patents were invalid, saying in a statement: "Qualcomm's illegal business practices are harming Apple and the entire industry".

"Apple began seeking those patents years before Qualcomm began seeking the patents it asserts against Apple in this case", the company wrote in its complaint.

The Apple patents cover technology that ensures that each part of a phone's processor draws only the minimum power needed, turning off parts of the processor when they are not needed and making sleep and wake functions work better.

In January, Apple charged Qualcomm for patent royalty rebates of around $1 billion that latter purportedly withheld from Apple.

Apple declined to comment on the new cases, referring to its earlier claims in its Wednesday filing that the company has developed its own technology and patents to power its iPhones. In a related suit, Qualcomm sued the contract manufacturers that make Apple's phones, but Apple joined in to defend them.
