I think you are referring to Apple and Apple's CMs (contract manufacturers) lawsuit against Qualcomm? These are really one single lawsuit orchestrated by Apple. The issue isn't overly complicated -- they are essentially refusing to pay Qualcomm licensing fees for their wireless patents on the ground that Qualcomm's licensing practice is in violation of antitrust laws. Thus, their claims rest heavily on the outcome of the FTC case.
