It seems that the ridiculous patent holders are trying to go out with a bang in 2008. Worlds.com, which holds a patent that never should have been issued on virtual worlds
has sued NCSoft, makers of a bunch of popular online virtual worlds
-- including some that were launched before
the patent was even filed for in 2000. The Register link above shows a few examples of such virtual worlds, but you can dig back even further. In 1996 I was using OnLive! Traveler which did all of the things described in the patent described, as can be seen in the video below:
Not surprisingly, the lawsuit is actually being brought by General Patent Corp (GPC), one of a growing number of IP licensing firms who prey on companies (that actually innovate) by trying to enforce incredibly broad and highly questionable patents. Not surprisingly, GPC's execs have been active in protesting
any sort of patent reform, claiming it would "mar innovation." I would suggest that patent reform is a hell of a lot less likely to mar innovation than suing innovative companies with overly broad patents that were applied for well after the technology in question was in common use.
