> If the Office becomes aware that information essential to its evaluation of registrability “has been omitted entirely from the application or is questionable,” it may take steps to cancel the registration. 44 Separately, a court may disregard a registration in an infringement action pursuant to section 411(b) of the Copyright Act if it concludes that the applicant knowingly provided the Office with inaccurate information, and the accurate information would have resulted in the refusal of the registration.
