A registration is subject to cancellation for fraudulent statements. Therefore, you must ensure that all statements made in filings to the USPTO are accurate, as any inaccuracies may result in the cancellation of a trademark registration. For example, the lack of a bona fide intention to use the mark with all goods and/or services listed in an application or the lack of actual use on all goods and/or services for which you claimed use in an application or post-registration filing could jeopardize the validity of the registration, resulting in its cancellation.
