Answer: The cancellation of a registered trademark means that the owner of the registered trademark submits a cancellation application to the Trademark Office, and the Trademark Office cancels the trademark. The required procedures include the following aspects: First, stamp the company's official seal on the "Trademark Cancellation Application" and "Trademark Agency Power of Attorney". Second, return the original Trademark Registration Certificate. Thirdly, if the trademark is required to be canceled due to reasons such as company bankruptcy, the local industrial and commercial department can apply to the Trademark Office for cancellation.
