Advanced Marketing Systems, LLC (AMS) filed a single suit in June 2014, but it recently expanded that to a litigation campaign with five new suits. Over the course of a few days, the entity sued Ahold, Brookshire, CVS, Hy-Vee, and Walgreen asserting a group of three patents (8,219,445, 8,370,199, 8,538,805). The patents-in-suit relate to discount/coupon processing retail systems. At issue in the suits are defendants’ consumer loyalty and reward programs that provide coupons for later redemption.
