I am informed that actually the Patent Office is at least starting to back away from 'on a computer' patents.

I confronted a rather weaselly dude attempting to patent troll tabletop roleplaying games by filing for a claim on character conversions, with an exceedingly vague 'with a computer' veneer over it. Fortunately the guy had his application rejected twice, and looked due to have it rejected again (as well as having attracted attention from much bigger fish) before he closed ranks and disappeared.
