Is Apple's Multi-Touch Patent Valid?

An anonymous reader writes "There is evidence that Apple's multi-touch patent application may have failed to list some prior art that showed gestures in multi-touch interfaces as early as the mid 1980s. Some of these examples even appear in the bibliography of Wayne Westerman's doctoral dissertation, and he's one of the inventors on the application's list. If true, that could leave them wide open for legal attack, should they try suing someone like Palm for patent infringement. Also, Apple may be infringing some key multi-touch patents owned by the University of Delaware — and co-developed by Westerman while getting his doctorate."

NOT!

Or we'll have 20 years of touch screen stagnation. Great. Just as we are trying to get out of classic mobile phone layout stagnation.

The Android G1 & Multitouch....

[Anonymous Coward]

Interestingly, the G1 android phone has built-in support for multitouch, as demonstrated here. However, there are some issues which make it more useful for pinch-gestures than other types. (See here for a description of why this is.)

Multitouch "proof of concept" pinch-zoom support has already been incorporated into unofficial Android firmware for the G1 (which incidentally is an AMAZING phone). If Apple's patent claims are busted-- and I'm still not clear on what types of multitouch it supposedly prohibits competitors from using-- it probably won't be long before we see multitouch show up on hardware that "officially" hadn't supported it previously.

No, you are only talking about damages. A patent is a right to exclude others from making, selling, etc.
35 U.S.C. 271(a):

Except as otherwise provided in this title, whoever without authority makes, uses, offers to sell, or sells any patented invention, within the United States or imports into the United States any patented invention during the term of the patent therefor, infringes the patent.

He is correct, patents do not require sale or commercial implementation by ANY party to be enforceable. Most patent holders won't go after DIY types who violate for personal use, but that's not because they have no legal ability to do so... rather it is because there is generally very little to gain by doing so other than bad publicity.
