According to the second paragraph of Article 17 of the Patent Law, the patentee has the right to indicate the patent mark on his patented product or the packaging of the product.
However, the status of rights must be clearly stated:
1. If it is not authorized in the application, it shall indicate that the product has applied for a national patent, and the patent application number is XXXXXXXX.
But you can't write unauthorized, for example, you have obtained a patent with the patent number ZL XXXXXXXXX, where ZL means authorization. It must be noted that this can only be used after authorization.
2. If the authorization has been announced, it can be expressed as: the patent right has been obtained, and the patent number is ZL XXXXXXXXX.
