For the better part of the year, Apple and Qualcomm have been at each other's throats. Apple initially claimed that Qualcomm was charging manufacturers too much for its processors and modems and taking advantage of its massive leverage throughout the mobile landscape, and this spiraled out into a multitude of different issues.

In the latest development to this story, Qualcomm is now suing Apple for breach of contract and claiming that the company provided Intel (one of Qualcomm's main rivals) with access to its modem software that's needed when creating chipsets for mobile phones.

The full lawsuit has yet to be made public, but certain tidbits are quickly making their way around the web. One particular section highlights the main reason for the suit, with Qualcomm wording the matter as follows:

During negotiations with Qualcomm, Apple exercised its commercial leverage and demanded unprecedented access to Qualcomm's very valuable and highly confidential software, including source code.

Qualcomm then states that it granted Apple limited access to "large portions" of its software and source code following Apple's claim that it needed this in order to tweak the code for its own hardware, but –

Upon information and belief, Apple has failed to comply with the restrictions on access and use that Qualcomm required in exchange for Apple's unprecedented access to software and source code.

However, that's not even the most damning part of the whole thing.

Apple uses Qualcomm's modems in devices like the iPhone and iPad.

Another snippet states –

Qualcomm's proprietary implementation of this communication protocol is not dictated by any standard and it contains Qualcomm's highly confidential trade secrets. Apple, however, included in the "CC'd Persons" distribution list for this request an engineer from Intel (a competitive vendor) and an Apple engineer working with that competitive vendor.

Yeah, that's huge.

Apple's been using Qualcomm modems in its hardware for years now. but starting with the iPhone 7, the company started to use Intel for certain versions of the device. Furthermore, it was also reported a few days back that Apple is developing iPhones and iPads that don't use Qualcomm's tech at all.

Apple has yet to respond to Qualcomm's latest allegation, but you can bet we'll be eagerly waiting to see it has to say.

Where did all of this Qualcomm hate come from?
