Inventor-controlled Vilox Technologies LLC filed its first wave of infringement suits, hitting Expedia (2:15-cv-01457), Foot Locker (2:15-cv-01458), Orbitz (2:15-cv-01459), Priceline (2:15-cv-01460), and TripAdvisor (2:15-cv-01461). In five separate complaints, Vilox asserts different combinations of a group of four patents related to “on-the-fly” search methods; that is, searches that can be refined by certain categories or keywords at any point during the query (6,760,720; 7,188,100; 7,302,423; 7,574,432). Vilox alleges that the search features of the defendants’ websites infringe the patents-in-suit.
