Inventor Holdings continued its campaign asserting former Walker Digital patents. In two recent filings, Inventor Holdings alleges that Sam’s West and Target are infringing a patent related to the sale and distribution of products in accordance to purchase agreements (5,970,470). The complaints accuse defendants’ online subscriptions services of infringing the patent-in-suit. The ‘470 patent has been asserted in litigation once before, by Walker Digital against Amazon in April 2011; the case remains open in initial pleadings. Inventor Holdings, a subsidiary of Patent Properties, acquired at least 22 patents from Walker Digital in November 2013, including the ‘470 patent. 6/19, Delaware District Court, 1:14cv00783, 1:14cv00784
