The legal battle between Apple and Qualcomm continues to heat up.
"Apple began seeking those patents years before Qualcomm began seeking the patents it asserts against Apple in this case", Apple said in its complaint.
Apple filed a new countersuit against Qualcomm, targeting the Snapdragon chips that power some of the most important iPhone rivals out there.
Earlier this year, Qualcomm accused Apple of infringing several patents related to enabling "high performance in a smartphone while extending battery life", and is attempting to get iPhones banned in the U.S. as a result. Qualcomm today announced that it is seeking an import ban on select variants of the iPhone 8 and iPhone X - Apple's latest releases.
The new complaints represent the latest development in a long-standing dispute and follows Apple's countersuit on Wednesday against Qualcomm.
United States shopping season starts with record high online sales
Online-only shoppers spent significantly less than consumers shopping in-store or across multiple channels. The amount spent on United Kingdom online retail sites on Black Friday 2017 was up 11.7% to £1.39bn.
Patent infringement has been Qualcomm's main offensive tactic in the courtroom fight. The processor only draws the minimum amount of power from the battery that an application or function of the phone needs, and is then powered down when it is not needed. Apple alleges it owns at least eight battery life patents that Qualcomm has violated.
"Qualcomm in particular rejects Apple's claim that its royalty demands are excessive, and it could use the threat of bans on cutting-edge iPhones as a strong bargaining chip".
The lawsuits ask for unspecified payments from Apple for the alleged patent infringement and for the court to make Apple stop using those technologies.
One of the three cases filed Thursday in a California court is a companion civil lawsuit to a new complaint also filed the same day with the ITC that seeks the remedy of banning iPhones with Intel chips, Reuters reports.
