Location Services IP, LLC (LSI) has added Comcast, Groupon, Priceline.com, McDonald’s, and Shopkick to a campaign targeting location-aware mobile apps and websites with location-mapping features (e.g. store locator services). Since launching this litigation campaign in February 2015, LSI has sued 24 companies over a group of related patents that generally concern location-based mapping services (5,839,088; 6,047,236; 6,202,023; 6,356,834; 8,935,220). Every case has involved at least three of the patents-in-campaign; some cases, e.g. those against AT&T, Foursquare, Microsoft, and Yahoo, have involved all five. Defendants include retailers, restaurants, banks, ride-share operators, wireless carriers, crowd-sourcing websites, and companies that offer mapping applications.
