Inventor-controlled DiStefano Patent Trust III, LLC (DPT III) has initiated its first litigation campaign, filing three suits, one each against Foursquare Labs (1:17-cv-00255), TripAdvisor (1:17-cv-00256), and Yelp (1:17-cv-00257). The complaints assert two patents (8,335,713; 8,996,398), from a twelve-member family, generally related to website implementation systems and methods that insert reciprocal links on separate constructed web pages. DPT III accused the defendants of infringement through the systems they offer for clients to develop customized web pages on the defendants’ sites.
