In a previous post I mentioned how the EOLAS patent could very well disrupt the way browsers work. Now I am glad to report that the US Patent Office has invalidated this patent, meaning that life can go on as normal, and Microsoft (among other brower makers) doesn't have to pay US$521 million in damages.
However there is a 60-day appeal period and I'm sure the company won't be sitting around waiting for big money to slip out of their hands when they could try, try again. A new battle is probably about to begin...
