Given the propensity of businesses to offer customer service through computerized platforms, it is perhaps no surprise that Patent Armory Inc.’s litigation campaign has spread so wide so fast. The plaintiff asserts a set of patents that includes some generally directed to customer service systems, focusing infringement allegations on tools within them for routing and triage. Earlier in August, Patent Armory hit Alphabet (Google), Avis Budget Group, Cruise America Travel, Enterprise Holdings, Hertz, Microsoft (LinkedIn), MBFG (Rent-A-Wreck of America), Penske (Penske Truck Leasing), Ryder System, Sixt Rent a Car, Sound United, U-Haul, and United Rentals, this past week adding additional complaints to its rapidly swelling litigation, one against each of AirBnB (6:23-cv-00590), Best Western (6:23-cv-00593), Choice Hotels (and its subsidiary Radisson Hospitality) (6:23-cv-00594, 6:23-cv-00604), Costco (6:23-cv-00595), Drury Hotels (6:23-cv-00596), Expedia (6:23-cv-00597), Extended Stay (6:23-cv-00603), Hilton Worldwide (6:23-cv-00600), Hyatt Hotels (6:23-cv-00602), Marriott International (6:23-cv-00603), Travelzoo (6:23-cv-00603), and Trip.com (6:23-cv-00606).
