Meanwhile, Intel is still selling their 4G modems for PCs but the company has made a decision to leave the modem business in future.
The US auto and tech industries have urged the US Court of Appeals for the Ninth Circuit to uphold a district court's antitrust ruling against chipmaker Qualcomm. However, Intel says that the sale was "grossly undervalued" and describes it as a "multi-billion dollar" loss to itself. "We filed the brief because we believe it is important for the Court of Appeals to hear our perspective", Intel's General Counsel Seven Rodgers, writes in a blog post.
"If Qualcomm decides to repeat its past behaviour in new IoT markets, it could demand a cut of every single improvement to millions of different products that just happen to be connected to the internet-even if the improvements have nothing whatever to do with that connectivity", the automakers said.More news: Portman Refutes Ukrainian Election Meddling Claims
The anti-competition spat between the FTC and Qualcomm has been going on for years now, though it did seem to come to a head over the summer.
The brief comes as Qualcomm prepares to challenge a court decision issued in May that found in favour of a FTC decision that Qualcomm's licensing practices for its wireless modem technology broke competition rules.
Intel is decrying Qualcomm's alleged anti-competitive business behavior as the chipmaker completed the sale of most of its smartphone modem business to Apple, putting an end to its latest bid to become a big silicon player in the world of iPhones and Android phones.More news: A smile from Carmelo Anthony reveals more than happiness, it shows evolution
Intel fought for almost a decade to build a profitable modem chip business. The trade group represented by US units of BMW (BMWG.DE), Ford Motor Co (F.N), General Motors Co (GM.N) and Toyota Motor Co (7203.T), among others claims that Qualcomm's licensing practices will have adverse effects.
On the other side of the fence, Qualcomm is mustering its own support. Qualcomm will fight this ruling to the dying breath, as while a fine is certainly unattractive, the decision fundamentally undermines the business model which has brought billions to the firm.More news: Qualcomm's New Fingerprint Sensor Lets You Scan Two Fingers at a Time
