Apple has filed a countersuit against Qualcomm, saying the chipmaker has violated a number of the Cupertino company’s patents, according to Reuters.
The suit, filed Wednesday in U.S. District Court in San Diego, is in response to the lawsuit Qualcomm filed against the iPhone maker earlier this year. Qualcomm accused Apple of breaching a number of patents related to helping mobile phones get better battery life.
Apple has denied the accusations and, on Wednesday, slapped back saying Qualcomm’s Snapdragon mobile phone chips violate eight of the iPhone maker’s battery life patents.
“Apple began seeking those patents years before Qualcomm began seeking the patents it asserts against Apple in this case,” Apple’s complaint reads.
This is not the only battle between the two firms, however. The fighting began earlier this year when Apple stopped its royalty payments and sued Qualcomm for $1 billion. Apple has alleged that Qualcomm was charging fees for technologies unrelated to its patents.
Qualcomm then countersued Apple, accusing the firm of using its “unprecedented access” to Qualcomm’s code to help the chip maker’s arch-rival Intel. Qualcomm sued Apple for breach of contract, saying the Cupertino company failed to protect the chip maker’s software.
The feud between the two companies appears to be a confirmation of a report from Reuters that Apple is creating iPhones without Qualcomm technologies, possibly for as early as next year.
