When we receive your request for an extension of protection from the International Bureau, we assign it a U.S. application serial number and put it in the queue for examination as a U.S. trademark application. We send you a filing receipt with your serial number. You can use this number to check the status of your application in the Trademark Status and Document Retrieval (TSDR) system.
If you are domiciled outside of the United States, you need a U.S.-licensed attorney to handle any responses, filings, or communication with the USPTO, so we recommend you appoint one now if you haven't already.
A USPTO.gov account is required to electronically file documents and respond to office actions.
