Re: Oh come on.
@TechnicalBen — from the main other phone companies they were for hard engineering technical patents.
Nokia's was about wireless technology and ended with an out-of-court settlement that guarantees ongoing licensing fees from Apple. I'm not knowledgable about wireless technologies to say a lot beyond that but I guess Apple accepted some sort of fault even if it legally didn't.
Motorola's claims against Apple have yet to be concluded as they've been stayed pending an EU investigation into whether Motorola have broken competition law by asserting rights over FRAND patents. Though an investigation is just an investigation and nothing more; maybe Motorola acted inappropriately, maybe not. Regardless the dispute is (i) whether Apple acquired a licence automatically because the Qualcomm chips it buys are licensed and are the component that contains the intellectual property; and (ii) if not, whether Motorola was bound by FRAND agreements and/or whether such an offer was made to Apple appropriately.
So technically that dispute is about whether the licensing steps Apple took were acceptable.
From the non-phone companies, the patents asserted have been less impressive. Creative Labs won shortly before the iPhone for hierarchical menus and continue to receive royalties as far as I'm aware. Kodak sued essentially because the iPhone could show a preview before taking a digital image (though, in practice, the lawsuit was actually about ownership of a related patent and whether Kodak could sell it in bankruptcy, though the issue was still that Kodak wanted money for digital image previews).
S3's claims included what appears to be a patent over taking a digital video signal in and sending an analogue video signal out, which sounds quite obvious to me but they ended up winning and then losing so probably sounded quite obvious to the judge. Another was essentially about the way the PowerVR does deferred tile-based rendering — rendering pixels from geometry in a certain order to maximise caching. I know S3 couldn't make the claim stick but I don't know whether it's because of a Motorola-type situation where PowerVR already pay the correct licensing or just because it was felt to be an obvious patent.
