Another week, another iPhone lawsuit or three. If it isn’t American’s complaining about AT&T’s 3G “network” (so bad, it’s made (Giga)Om Malik abandon his iPhone), it’s owners of white iPhones complaining about cracks in their plastic casings (which is effecting other, non-iPhones as well, making us suspect someone spike a plastic factory somewhere in China). This time, however, it’s a patent dispute, and it’s not Apple going after Palm, but Picsel Technologies taking it to Apple. According to Apple Insider:

By using particular techniques to speed up panning and zooming for images and other documents, Apple is effectively borrowing Picsel’s own acceleration to make the iPhone work as smoothly as it does, the complaint reads. [..]Unlike many of these suits, the plaintiff already has major customers for its software that primarily include Japanese firms like KDDI and Sharp but also include American phone manufacturers such as Motorola and Palm.

So even though Apple now owns multi-touch(ish), they may not be allowed to show it working on screen? Gotta love patent poker…
