Prior Art February 21, 2006Posted by Florian in GPE, Maemo.
According to an ars technica article (http://arstechnica.com/news.ars/post/20060217-6212.html) Apple seems to own a fresh patent (filed 16 September 2005) which covers all sorts of on-screen keyboards for touchscreen devices. This affects not only hildon-input or matchbox-keyboard but much older implementations like XKBD (first release in summer 2000) too. Of course there are a pile of much older commercial products as well.
It should not be complicated to prove prior art… but unless someone does, it is a valid US patent. Sometimes i really wonder how these things happen… and feel really lucky that i’m not in the US.
