A bit harsh to call a company/inventor who is producing touch panel displays / screens since more than 15 years a "patent troll". Their solutions are in use and new ones created all the years since then (see http://www.bizjournals.com/philadelphia/stories/2008/03/10/story4.html http://www.bizjournals.com/philadelphia/stories/2008/03/10/s...). Key question is if Apple with their technology have infringed these patents. Apple does reference the patent themselves for 3 of their own applications. If you have a look at the drawings they (together with the text) do describe the use of gestures including pressure on haptic touch devices to manipulate elements on the screen. Again this patent does not have priority from 2005 but from 1997 when it was originally filed.
