What are the main ways to conduct trademark inquiries? In the past, trademark inquiries could only be conducted on-site at the Trademark Office. Applicants needed to inquire about trademark registration information at the Trademark Office office in Beijing. Now, with the development of the Internet, trademark inquiries can be directly implemented online. It is still the Trademark Office. Now, there is no need to apply on the spot. You only need to log in to the official website of the Trademark Office of the State Administration for Industry and Commerce and enter the trademark query page to query trademark registration information. Of course, in addition to this, there are also various websites of trademark registration agencies and intellectual property firms, where you can also query trademark registration information.
