Lz, this application number is the application number of an appearance patent, and the number after the year in the application number is 3, which is an appearance patent; The number behind is the patent for utility model; The number after 1 or 8 is an invention patent.
In addition, patents are regional, and patents of one country/region are only protected in that country/region. This applicant may not have applied for the same patent in the United States or Germany, so he can't find it.
Supplement: According to the current patent law, if the product has been circulated in China before the date of application, then the application does not have novelty as stipulated in the second paragraph of Article 22 of the Patent Law and cannot be authorized. Even if it is authorized, it can be invalidated. Of course, you have to have proof.
If it has been circulated in the United States and has not yet entered China, it is still novel and effective.
If you want to check whether the products are available in the United States or Germany, you can go to the website of the European Patent Office or the United States Patent and Trademark Office. But if you don't know the patent number of this product, it will be difficult to find it.

See Article 1 1 of the Patent Law for details of the infringement.
Supplement 3: This should not happen. Because B only produced the product in China before, but did not sell it in China, that is to say, the product has not been published in China, so the novelty of A company's patent cannot be destroyed. China's patent system is based on the principle of first application, that is, whoever applies for the patent right first will belong to him, whether you invented it before the other party or not. Now Company A has applied for a patent. According to Article 1 1 of the Patent Law, Company B cannot produce in China, because such production is obviously for profit.
Supplement 4: Well, if the publication date of the patent applied by Company B in the United States is earlier than the filing date of the patent applied by Company A in China, then the patent of Company A in China can be invalidated on this basis. Invalid request shall be submitted to the Patent Reexamination Board of China National Intellectual Property Administration Patent Office, because the patent of Company A is not novel.
If the publication date of the American patent of Company B is later than the filing date of the China patent of Company A, there is no way out.
The patent right is regional, and the patent right of a country is only valid in that country. Whether you apply for a patent in another country has nothing to do with whether you can get the same patent in another country.
