If the trademark registration certificate is lost, you can take the following steps:

1. Find a backup copy:

First, find whether there is a backup copy of the trademark registration certificate copy. You may have kept a backup copy of your trademark application or archived it on an electronic device or in cloud storage. Check these locations to see if you can find a backup of the missing certificate.

2. Contact the trademark registration agency:

If you cannot find the backup copy, your next step should be to contact the trademark registration agency, such as the National Trademark Office or the Trademark Registration Office. Report the loss of your trademark registration certificate to them and seek their guidance and advice.

3. Submit an application:

The trademark registration agency may require you to submit a formal application explaining the loss of the trademark registration certificate and provide relevant supporting documents and identification. These documents may include proof of identity of the applicant, copy of the trademark registration certificate (if available), loss statement, etc.

4. Reissue a trademark registration certificate:

According to the requirements of the trademark registration agency, you may need to pay a certain fee to reissue a trademark registration certificate. The trademark registration authority will process your application and issue a new trademark registration certificate.

It is important to take action as soon as possible, promptly report the loss of the trademark registration certificate, and apply in accordance with the requirements of the trademark registration authority. This ensures that your trademark rights are protected in a timely manner and a new registration certificate is obtained.

Please note that specific reissue procedures and requirements may vary by country or region. It is therefore recommended that you contact the relevant trademark registration authority directly and follow their guidance and requirements.
