Didn't Apple say they had all sorts of patents when they first introduced the iPhone?
Jobs made the claim of hundreds of patents, although it was pretty clear to us engineers that he must've included every patent on every chip used in the iPhone that was made by anybody. Just the usual salesman hyperbole.
So why are there so many lookalike devices out there? I've never understood which aspects of the iPhone are patented, unlicensed to others, and therefore supposedly patent infringements when "borrowed" by anyone else.
The iPhone looked like a lot of devices that came before it, too. Swipe to unlock, inertial scrolling, pinch zoom, double-tap webpage zoom, large buttons, etc, all were known features in previously publicized projects. (Most consumers had never seen those things, however, which is why they were so impressed. )
The only slightly novel UI patents Apple got recently, were about rubber-banding at the end of screens, and for vertical scroll locking. Since a lot of OS's do those things, Apple is using those two patents constantly in their complaints.
Apple have already lost some of those patents and others may not be valid.
I don't know if Apple has actually lost any iPhone-related patents (yet), but they've certainly lost cases brought against them over visual voice mail, and likely will lose soon over some browser and camera related items. But then, almost every phone maker got nailed on all those.
You might be thinking of the recent ITC staff memo saying that they didn't believe that some of Apple's patent claims were infringed by Nokia, and possibly weren't even valid patents.
To recap the Apple v. HTC / Nokia / Motorola claims:
- Apple used 5 of the same patents against both HTC and Nokia, so ITC removed the five common ones from the original Apple v Nokia claim, and lumped Nokia+HTC together against Apple on those.
- Apple used 5 other patents against HTC.
- Apple used 4 other patents against Nokia. Those were the ones which the ITC staff said were not infringing and probably not valid.
- Three of those four were also used by Apple against Motorola. So that case is also weakened a bit.
The ITC complaints are only meant to try halting import (leverage). The real patent trials for royalties and damages filed in Delaware and Wisconsin have partly been put on hold pending the ITC decisions. Thus the fairly quick ITC decisions will have influence over what juries decide over the next few years.
E.g. let's say the ITC throws out Apple's claims against Nokia. The jury in Delaware is then likely to side with Nokia's claims against Apple, and award Nokia not only the billion dollars in lost GSM royalties, but perhaps give Nokia triple that for damages.
