Coding Technologies, LLC, a Texas NPE formed by prolific inventor and frequent patent plaintiff Leigh M. Rothschild, has filed suit over one of the seven patents that RPX reported in May had been transferred to the new entity from an Intellectual Ventures LLC (IV) affiliate. The patent asserted generally relates to providing content from a server in response to a photographic image taken of a “code pattern”. Coding Technologies accuses 17 defendants—American Airlines, Apache, BNSF Railway, Ben E. Keith Company, Cabot Oil & Gas, Dickey’s Barbecue Restaurants, Halliburton, Huntsman, Keller Williams Realty, Mary Kay, MRC Global, Omni Hotels, Powell Industries, Schlumberger Technology, Spectra Energy, and Stewart & Stevenson LLC—of infringement through their delivery of a web page after a user has snapped a picture of a QR code with a “user terminal” (i.e. a smartphone). Nine of the complaints were filed in the Eastern District of Texas; the other seven, in the Southern District.
