How do I know whether the patent I applied for has entered the actual review stage?

Is it October this year? Trademark registration will send you a trademark acceptance notice from January to March. After the trademark notice is obtained, the trademark will go through a preliminary review stage. During this period, there will be a three-month vacuum period, so you cannot find the trademark registration. situation. But if it can be registered later, you can check it on the China Trademark Network. If not, you will also receive a rejection notice.
