Do you want to check whether your product infringes on others’ patent rights? Then a large number of searches are required. If the product is only sold in China, you only need to search for domestic patents. If it is also sold in other countries, you need to search in the corresponding country.
If you want to apply for a patent, but you are afraid that others have already applied and you will not be able to get the authorization, you also need to conduct a more comprehensive search. You can go to the official website of the State Intellectual Property Office and search on platforms such as Baiteng and soopat. arrive.
In addition, search is also an extremely professional and cumbersome matter. If the economy allows, it is best to find a professional patent agency to do it.
