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."

I sincerely hope

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.

I'm sorry, but are you somehow implying that patent law can be used to hinder competition in a so called 'free market'? Shame on you, sir.

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.

My guess is that Apple will follow this discussion

Considering the large number of unpaid sales and public relations staff Apple has here at Slashdot, I wouldn't be surprised.
