The suits, filed on Wednesday in Chicago federal court name Zillow, RealPage and LoopNet among other infringing on a 2006 patent, "System and method for locating and notifying a user of a person, place or thing having attributes matching the user's stated preferences" (7071842). The patent is about matching people with local preferences, a key to pretty much all current LBS solutions. Earthcomber filed similar suits in past years and claims to have come to agreements, though in at least one case the suit was ultimately dismissed. Zagat reached a deal (APB coverage).
