Chapterhouse LLC, an affiliate of monetization firm IPValuation Partners, LLC (IPVal), has filed its first lawsuit, accusing Shopify (2:18-cv-00300) of infringing four patents broadly related to generating and storing information about a product and/or a sales transaction, including receipts for such purchases. At issue are various aspects of Shopify’s “ecommerce platform system”, including features that generate electronic receipts and sales reports, provide transaction notifications, insert links into email notifications designed to induce customers to complete idle transactions or to make secondary purchases (with that feature provided by the Spently add-on), and to export a list of orders. The website for the patents’ original assignee AfterBOT (with latest copyright in 2013) advertises that entity’s “intellectual property rights for digital receipts”.
