How do I know whether my invention has been patented or how to inquire about related patents?

Hello, if you want to know whether a product has been applied, you can find relevant information through some searches.

You can ask an agency to help you search, because if you are a novice patent, the searched patents will not be very targeted, that is, the search will not be very comprehensive.

Regarding the search, it is very convenient to enter relevant information on the SOOPAT website (which can be found directly by Baidu SOOPAT) and search for all the information about the patent.

For example, company name, applicant's name, address, product keywords, etc.

If you have any questions, please call me at any time and answer them wholeheartedly.

I hope you can click the thumb in the lower right corner and give yourself a valuable 1 point. Thank you.

Website: I said in my answer that Baidu does not publish websites directly. There are many agents in Beijing, all of which are acceptable.
