Very broad language – taken at face value, Apple effectively owns the IP rights to multi-touch in the U.S. This sucks.
DF’s major beef is with the patent office awarding the patent in the first place due to its broad language. However, what other type of language does one use for the concept being patented? We’re talking a whole new UI here. The implication seems to be that the patent is short on specifics, yet it’s 358 pages! When you’re patenting a new UI, I’m thinking you’re going to have to brush with broad strokes lest you forget a corner of the canvas that a competitor uses to white out your picture.
