Earthcomber, a Chicago startup, filed suit against Loopt, a Mountain View startup, for allegedly infringing on a patent that lets "a system and method for locating and notifying a user of a person, place or thing having attributes matching the user’s stated preferences." Yawn. To spice things up, Earthcomber today added TechCrunch, the blog of blowhard Michael Arrington, to the lawsuit. Why? Ostensibly because Earthcomber's CEO couldn't find Arrington's phone number. So much for locating users. [TechCrunch ]
