How much can a patent with an annual output value of 1 100 million be sold?

In principle, patents can't sell much money. It is impossible for an enterprise to spend hundreds of millions of yuan on patents, and it is also a very large enterprise that can spend hundreds of millions of yuan on patents. General enterprises and inventors agree to take a certain proportion of net profit, such as 10%, so that a patent patentee with an annual net profit of 10 billion can get a gross profit of 1 0 billion every year.
