Worlds Inc (WDDD)

[Wagman7]

What I'm having a difficult time getting my head around is why a patent can be invalidated (wouldn't the 101 process/test have been applied to obtain the patents in the first place)? I can understand an argument that a different process or methodology was used, which supports why one's technology doesn't conflict with an existing patent, but it almost sounds like Casper's saying that World's 1995 patents are no longer patents at all.
