How to check whether the patent you applied for is pct?

Inquiring whether the patent you applied for is a PCT patent can be carried out through the following steps:

1. Log on to WIPO-PATENTSCOPE website.

2. Enter query keywords in the search bar, such as patent name, patent number, patent applicant, inventor and other information.

3. Filter according to the query results, and the screening conditions can be country, patent type, patent status, etc.

4. Select the patent of interest in the query results, and view the detailed information, including patent abstracts, patent claims, etc.

5. If the patent has entered the PCT application stage, the relevant information of PCT application will be displayed on the patent details page, including PCT application number, international publication number, international publication date, etc.

It should be noted that PCT application is only a patent application method, and the applied patent may not enter the international stage for various reasons, so the PCT related information in the query results may be empty.
