Help: I want to inquire about the IPC distribution of patent applications in a certain area. I don't know how to inquire. Please describe it in detail. Thank you.

You have to go to soopat (search the website directly in Baidu).

After input, click on the table to search.

Then enter the address you want to look up in the address, but this method seems to be only as economical as possible.

Then click soopat analysis.

The results will include the applicant, application date, publication date and the classification number you want.
