I wonder who owns those old Wugofski patents assigned to Amiga LLC. They clearly cover the same ground. On the other hand they don't make a claim for this aspect on the grounds that it's established art, so there's no money to be made selling the patent to MS, alas ;-)
The patent is valid, but that's not to say it's enforcable. Much of what is described has been covered before. Internet linked EPGs were proposed as part of the TV Anywhere DAVIC standard in the mid '90s.
