Inventor-controlled Mimzi, LLC has filed suit against Foursquare Labs (1:18-cv-01767) and Trip Advisor (1:18-cv-01768) in Delaware. The new complaints assert a single patent broadly related to returning location-based information from a “social network database” in response to a spoken request. At issue are the defendants’ mobile apps, which allegedly permit users (i.e., smartphone users) to view “location-dependent information” in response to questions asked (“Where is the nearest (best, most popular) Chinese restaurant?” given as an example).
