Apple claims that both Samsung and Motorola infringed on their touch event model patent (EP2098948), but the Mannheim Regional Court just came down with a decision in favor of Samsung and Motorola. The touch event model patent shouldn’t be mistaken for multitouch. This one is a fairly broad patent (not like all the others aren’t) that covers the way the operating system reports or disregards touch events to applications. This could have been a mess for both Samsung and Motorola because if Apple had won, the result would be a need to rewrite, recompile, and reinstall a lot of apps since numerous applications rely on the operating system functionality.
The defense was based on the fact that Android does not store a multi-touch flag in association with each “view”, and this same argument was already successful in the UK and the Netherlands. I’m sure Apple will appeal this ruling just like they did with those.
