After receiving your recordation notice, please wait at least one week before checking TSDR to see if the ownership information has been automatically updated. Go to Trademark Status and Document Retrieval (TSDR) , enter the serial number, and click on the Status button. Scroll down to the "Current Owner(s) Information." If the change in the owner has not been entered, go to the "Prosecution History" and look to see if there is an entry that says "Ownership records not automatically updated." If the records were not automatically updated, you must notify the Trademark Operation in writing so that the records can be manually updated.
