Is this USA only? (Score 1)

With all this patent trouble, why does it seem its localized in the US? Does any other country have similar problems. I've worked in the software industry for 20 years and though I admit my experience on the legal size is not broad, the only close-to-home experience was when a US competitor decided that having a feature that increasing the size of a wall caused the price of that wall to increase violated their patent. This is the kind of foolishness that eventually starts wars between nations.
