There are a lot of cases regarding Qualcomm's licensing scheme, but the 'fighting qualcomm' came first. In 2015, the Korean FTC launched an antitrust suit against Qualcomm & Apple testified in it. Qualcomm said that Apple mislead & withheld information from the KFTC. They've also stated that this breeches the terms of their licensing agreement, and Qualcomm hasn't given Apple any rebates since. Apple disagrees, and in January 2016, they sued Qualcomm over it. Put simply, their argument was that they were owed all the withheld rebates, because they hadn't broken Qualcomm's terms. The anti-trust implications of the license were mentioned, but weren't really the point. The broader anti-trust suit in the US was brought by the FTC just a couple of days prior, so a lot of news blended the two together. Apple, provided information in the FTC's case, and Qualcomm has sued Apple over that too.
