The Fingerwork touchpad was a input devise attached to a computer. When Apple purchased Fingerworks the got their mult-touch patent which was used to create the multi-touch for the iPhone and iPad. So why is Elan's patent they purchased from Logitech not applicable against Apple?

Elan sued Synaptic in 2006, before the iPhone was launched. In 2008 they won and Synaptic licensed Elan's multi-touch technology. I suppose they wanted to win their patent suit before going after Apple.

I have been following this story since April of 2009. This link http://www.billbuxton.com/multitouchOverview.html is the best explanation of how multi-touch technology was created.

Over 30 years in IT fried my brain. Since I retired I have been a river guide and a construction worker . I am now making maps. ArcGIS and my *&^%$ Dell crash frequently giving me HBP again. Next up is pine straw farming.
