How do you know if your invention has a patent?

Hello, if you want to know whether a product has been applied, you can find relevant information through some searches. \x0d\ Search can ask an agency to help you query, because if you are a novice patent, the searched patents are not targeted, that is, the search is incomplete. \x0d\ \x0d\ About search, you can find all the information about the patent by entering relevant information on the SOOPAT website (Baidu SOOPAT can be found directly), which is very convenient. \x0d\ \x0d\ such as company name, applicant's name, address, product keywords, etc. \x0d\ \x0d\ If you have any questions, please contact me at any time and answer them wholeheartedly. \x0d\ I hope you can click "Agree" on the thumb in the lower right corner and send your precious 1 point. Thank you \ x0d \ x0d \ website. As I said in my answer, Baidu will not post the website directly. There are many agents in Beijing, all of which are acceptable.
