And... here we go again. A company named Tsera LLC, a Texas company that has no products or online presence, and which certainly appears to be a typical patent hoarding shell company has now
sued a bunch of companies in East Texas (of course) for patent infringement. Of particular interest are the claims against Apple and Microsoft. The patent in question,
6,639,584 is for some sort of touch interface, and the lawsuit claims that the iPod and the Zune both use touchpads that infringe on the claims in the patent. Of course, the patent itself seems to cover some slightly different things, as the article notes the system doesn't have visual feedback and users don't need to view the device. That's not quite the way portable music devices work... Once again, this appears to be a blatant money grab by some folks who had nothing to do with the actual advancement in this space.
