How can you ensure your trademark documentation is properly handled if it's not found in TSDR?

The approach of following up with an email that includes your filing receipt is the most effective and proactive step to take if your trademark documentation is not found in the Trademark Status and Document Retrieval (TSDR) system. By including your filing receipt, you provide the USPTO with critical information such as your application number, the date of filing, and other identifying details relevant to your case. This information enhances the ability of USPTO staff to locate your documentation and address the issue promptly.

A letter documenting the issue could also be useful, but it may not provide the same immediacy and clarity as an email that includes specific details from the filing receipt. Notifying an attorney can be helpful depending on the circumstances, especially for more complex issues, but it might delay the resolution since you would be relying on an intermediary to address the situation. Simply waiting for further updates is not advisable since it does not take active steps to resolve the issue, which could prolong the time it takes to rectify any problems with your trademark registration.

In summary, directly following up with the USPTO by email and including the filing receipt provides the most efficient and clear pathway to ensure your trademark documentation is properly located and handled.
