InterTrust is suing Microsoft for infringing on their patent with the Windows Product Activation. This is ridiculous. Worse than Amazon's one-click patent. Ed Fish, President of InterTrust's MetaTrust Utility Division said. "Microsoft's 'product activation' technology prevents a user from continuing to use Windows XP unless the user has 'activated' the software, meaning that the user has received electronic authorization. InterTrust anticipated these DRM processes many years ago and our issued and pending patents serve to protect our ingenuity and investment in them." Right. I should take out a patent on taking the train in to work and sue everyone on the train!
