strokes-mode and touchscreen patents? was Re: emacs and touchscreen

[David O'Toole]

Something occurred to me today after watching my touchscreen
strokes-mode video. Could the gesture recognition in strokes.el either
1. be threatened by patents that existed prior to 1997 (the first year
of copyright listed in strokes.el) or 2. qualify as prior art for
techniques patented later?
