"All this blog post is one person's misunderstanding of patent and copyright law": If you refer to the current patent laws in the USA, then you're probably right. But I think that laws that grant the possibility to give anybody a 20 years monopoly on something like "double tap to zoom" (or "1-click purchase") are completely against the original spirit of patent laws, very stupid, and, most importantly, pose a severe risk of slowing down innovation almost to a halt.

I just hope that this madness will not come to the EU too (eg the 1-click patent was never granted here).
