Qualcomm suit claims Apple breached contract, shared proprietary info with Intel

The lawsuit is part of an ongoing legal battle between the two companies.

Qualcomm later asked the US authorities to ban imports of some iPhone and iPad models and filed a complaint with the US International Trade Commission, accusing Apple's iPhones and iPads of infringing six of its mobile patents.

The report claims that the final straw for Apple was when Qualcomm allegedly made a decision to withhold the software needed to test Qualcomm's own chips on Apple's prototype devices.

Apple will reportedly not use any Qualcomm components in 2018 (CNET/CBS Interactive). Qualcomm reckons that Apple used this access to help Intel in its quest to compete in the LTE modem market.

The lawsuit also claims Apple did little to stop the valuable Qualcomm information from being shared with Apple engineers who were working with Intel.

The chip maker's latest move takes the form of a lawsuit that was submitted to the California state court in San Diego on Wednesday and hit the news cycle this morning.

Apple declined to comment on the suit.

In July Intel filed a statement with ITC claiming Qualcomm is trying to Force them out of the modem business with Apple.

In Qualcomm's earnings report yesterday, the chipmaker revealed that full-year QTL segment sales had fallen 16% due to Apple and another unnamed licensee withholding royalty payments.

According to law firm, Bernstein Litowitz Berger & Grossmann, which serves as lead counsel for the lawsuit, "Qualcomm's clear-cut anti-competitive practices dealt a swift and severe blow to the value of the company's shares, causing Qualcomm's stock price to plummet 33 percent during the class period, erasing over $32 billion in shareholder value".
