Your license has just changed to a new address, right? Then I want to change the address on the trademark! If it is a written application, just fill in the other answers. If it is an online self-application, you must first log in to the application system, operate in - My Account - User Change (refer to the picture), change the address in the user information before applying. For subsequent trademark change applications, the reason why your address bar is gray is that it defaults to the correct new address. You must ensure that it is the correct new address. The reason why you only change the address without uploading supporting documents is because the user information already has a license certificate. File (but make sure it’s up to date)
