Trademark revocation is due to long-term idle and non-standard use, and the trademark is invalid because it does not have legitimacy, distinctiveness, non-functionality or does not meet the priority; Trademark cancellation means that the trademark owner gives up the right to renew his trademark, and the three cannot be confused. Obtaining trademark registration by deception belongs to the situation that the Trademark Office can take the initiative to be invalid, and it is not revoked, and A excludes it. If the trademark owner changes the registered trademark by himself, it is revocable, and C chooses. When the extension period expires and is not renewed, the trademark owner gives up the trademark right by implication, which belongs to the revocation of the trademark and B error. Infringement of prior rights belongs to the case that the application of the parties is invalid, and D is wrong.
