I have a patent for utility model, and I want to transfer it. Did anyone ask me to buy it after the national bureau was made public?

Hello, after this utility model patent is published, the representative has authorized it. There is a period of two months between the notice of granting the patent right to you and your payment. At this time, selling patents is the most cost-effective and the price is the highest. This kind of patent is called certificateless authorization. At this time, the right is transferred and the buyer can get the patent certificate that the patentee is his own. Once the certificate is issued, the patent certificate will not be made again in the future. Even if it is sold to others, the patent certificate belongs to the original patentee. Therefore, I suggest you sell it quickly. If there is no channel, you can find various patent transfer websites on the Internet for promotion.
