Now you can only check well-known trademarks on the Trademark Office website. If you want to check similar trademarks, you can check them on third-party websites such as Social Standard Network. After you log in to the Trademark Office website too many times, The website cannot be opened. By the way, the social standard website can search for graphic trademarks. You can directly upload graphic trademarks with one click to search for similar graphic trademarks. Hope this helps.
