Background
WP Engine filed suit alleging interference, unfair competition, defamation, and Lanham Act violations, along with Computer Fraud and Abuse Act claims. The court found portions of the antitrust and CFAA extortion pleadings insufficient but allowed amendment.
Several surviving claims arise from alleged statements on WordPress.org and at public events. WP Engine also alleges unauthorized plugin conduct underlying the CFAA unauthorized access count. The rulings allow discovery and litigation on the surviving counts to proceed against Automattic and Matt Mullenweg.
