We see patent lawsuits all the time. However, the case being brought against Twitter by TechRadium actually seems legit, according to attorneys consulted by Wired’s Threat Level blog. It’ll probably get settled with some sort of licensing deal but it’s still not something the Twitter people want to deal with, considering they’re still trying to figure out a business model.

The company says it didn’t care about Twitter when the Twitterati was watching the tweets of NBA superstars, musicians, politicians and news outlets. But then TechRadium began seeing promotional materials and news accounts of companies, school districts and local governments using, or considering adopting, the microblogging service as their emergency notification system – muscling into TechRadium’s wheelhouse.
