The new complaints again assert a family of four patents (6,098,882; 6,176,427; 6,820,807; 8,281,999), generally related to encoding digital data in a machine-readable format, with the defendants’ accused products and services targeted for their use of QR codes. Extensions of the deadline to answer have been granted in the cases from the first round, filed in March of this year against Citigroup, General Mills, J.D. Power and Associates, NeilMed Pharmaceuticals, Pioneer, Procter & Gamble, and SunTrust Banks.
