The claims for the pinch-to-zoom patent are broad enough to cover pinch to zoom on any touchscreen.

The claims as-filed, sure. But the USPTO doesn't generally update the published application to match the current document (including changed and struck claims) during the process.

So it's entirely possible that wording didn't survive.

In any event, it's hardly fair to judge a system based on the snapshot of a submission from before it had even gone through that system yet.

You can easily read all of that in the public PAIR database, it's not hard to find.

Btw the wording did indeed survive, the patent as it stands is sufficiently broad to cover all pinch-to-zoom implementations on any kind of touchscreen.
