The method is as follows:
The first step is to log in to cpquery.sipo.gov.cn. Click "Click to enter" under "Public *** Query".
In the second step, click "Agree to the above statement" and then click "Continue".
The third step is to enter the query page.
The third step is to enter the name of the patent to be queried in the "Invention Name" column, such as "Bicycle", and then in the "Verification Code" column, enter the result calculated according to the prompts on the right. Click "Query".

In addition to the patent query website cpquery.sipo.gov.cn, we also recommend Runtong patent search. The website provides txt files and supports fuzzy queries.
For example, search for "bicycle" related design patents.
The first step is to log in to Rainpat (www.rainpat.com).
The second step is to enter “Bicycle” in the “Chinese Patent” column.
The third step, click "Run," then all 81,911 patents related to bicycles are listed.
