Status 641 means the USPTO mailed a non-final Office Action identifying issues with your application. You typically have three months to respond with arguments, amendments, or evidence. Missing the deadline can abandon the application.

The USPTO has raised a concern regarding your trademark 'LUCAOS', citing a potential likelihood of confusion with two existing registered trademarks. We will need to review these findings and discuss potential next steps with you.
