"It's been a while since we last looked in on the IP Innovation LLC v. Red Hat et al patent litigation. In fact, it's been exactly a year. The parties are deep in discovery, with trial set for April 12, 2010[PDF]. That could change, of course. But that's the date set. IP Innovation thinks the trial will take 3 days while Red Hat and Novell estimate between 7 and 10. It takes longer to defend yourself from a patent infringement accusation than to just throw one out there."
