Chegg (CHGG-6.2%) shares continue to slide on news that former partner Pearson (PSO-3.1%) is suing the company for selling answer sets to Pearson textbooks through its website.
“By using and copying Pearson’s original creative content to make answer sets based on that content, Chegg infringes Pearson’s exclusive rights as a copyright holder, including the rights of reproduction, preparation of derivative works, and distribution,” wrote Pearson, arguing that Chegg makes the majority of its revenue from selling answer sets.
Chegg says that less than 10% of new subscribers use answer sets and only a fraction use Pearson content. Pearson is seeking an injunction ordering Chegg to stop its alleged copyright infringement along with unspecified damages.
