Malwarebytes had previously filed its Petition for Rehearing and Rehearing en banc in response to the Ninth Circuit's ruling in favor of Enigma Software in the appeal of its lawsuit against Malwarebytes − and the Ninth Circuit’s ruling that Section 230 of the Communications Decency Act is "not limitless" as claimed by Malwarebytes.
