Apple (Fingerworks?) patented their implementation of multi touch. Whether you agree with them being granted those patents or not, they were. And this case wasn't about whether those patents were valid or should have been granted in the first place but about if Samsung infringed on them.It's not about who is selling which products, we are talking about patents, thus about inventions and innovations.
Apple were the first company to introduce multi-touch to mobile phones. But multi-touch was around for decades, and so was the "pinch to zoom" gesture.
They have no right to patent it just because they've used it in a phone.
Also, who cares how long something has been around if it isn't being used in products that are being sold to consumers (i.e. implementation). If multi touch and pinch to zoom were around for 40 years how come Motorola, Nokia, Palm, RIM, Sony Ericsson, etc. didn't bring it to the mobile phone first?
