Teksyndicate ran a contest about a month ago that if anyone can name something Apple invented they would get a prize. They made a video and put it up on youtube. In that video they disprove many of the entries sent in, one of which was "pinch to zoom."
The other thing is Nokia has a buttload of patents, they spent an enormous amount on R&D so I'm pretty sure they wont try pulling that one on Nokia because Nokia would expose how it is really prior art.
I haven't read that multi touch patent but I'm guessing it's not for resistive screens which is a possibilty that Jolla might use it since they will release in China. That said, if I was in a dinghy and their was great whites nearby dueling I'd be kinda nervous.
