German patent website

Do you want to check whether your product infringes the patent right of others? This requires a lot of search. If the product is only sold in China, you only need to search for domestic patents. If there are sales in other countries, you need to search in the corresponding countries.

I want to apply for a patent, but I'm afraid someone else has already applied for it, so I can't get the authorization. I need to conduct a more comprehensive search, which can be found on platforms such as official website, Baiteng and soopat of the National Information Bureau.

In addition, retrieval is also a very professional and tedious thing. If the economy permits, it is best to find a professional patent agency to do it.
