Are the National Copyright Administration and the Trademark Office networked?

Hello, the National Copyright Administration and the Trademark Office are inquiring about the National Information Network.

Trademarks are under the control of the industrial and commercial bureau, and the intellectual property office only cares about patents. The Intellectual Property Office only deals with patents and so on. While others only play a coordinating role in foreign affairs. Copyright is in the Copyright Bureau, and trademarks are in the Industrial and Commercial Bureau. At present, the main intellectual property organizations are the Copyright Bureau and the Trademark Office, and of course the Patent Office, which can't be found on the national information network.
