So far in August, GreatGigz Solutions, LLC, one of several entities controlled by prolific inventor Raymond Anthony Joao, has sued Costco (6:21-cv-00807), CVS (6:21-cv-00808), Walgreens (6:21-cv-00809), and Walmart (6:21-cv-00798), all in the Western District of Texas. The four patents-in-suit are generally related to providing employment hiring services over a network, with the defendants accused of infringement through the provision of their respective platforms (e.g., e-commerce websites and mobile apps) for “order[ing] groceries and other items online”. At issue are features for matching “shoppers” with customers for scheduling deliveries, with Costco, CVS, and Walgreens further accused over the use of the Instacart platform and Amazon Web Services data centers and Walmart accused over its Spark Driver platform.
