> When did Apple patent pinch-to-zoom? This video is from 1988.
The video is from 1988, but it appears the work was around 1983. The pinch-to-zoom (on 'portable communication devices') patent[1] was filed in 2006, issued in 2010.
If that is the case, what about the Jeff Han video which came out in 2006? Jeff Han was obviously working on it for at least a year before he gave that talk. Shouldn't that be obvious prior art? He talks about pinch and much more!
