On August 12, 2019 the law firm of Susman Godfrey LLC filed a class action lawsuit against Cengage Learning on behalf of Douglas Bernstein and four other authors. Three days later, a similar suit was filed by Slarskey LLC on behalf of Grafton H. Hull.

Both cases reflect elements of a 2018 lawsuit against Cengage Learning by authors David Knox and Caroline Schacht, which was handled by Slarskey’s firm. At issue in all of these cases are Cengage’s emerging publishing practices and royalty calculations associated with its digital MindTap platform and the Cengage Unlimited subscription service.
