What's the difference between the fees of general license and exclusive license?

Patent license is divided into ordinary license and exclusive license, and the difference in cost between them is very huge. According to the difficulty and income level of patent implementation, the patent exclusive license fee can usually be as high as 5~8 times or even higher than the expected annual total income of patent implementation; The collection of patent general license fee is also based on the value of the patent itself. If the patent value is high, the proportion of the general patent license fee can be charged at 50%~ 100% of the total expected annual income from patent implementation. Of course, there are also cases where the ratio of the above two license fees exceeds, mainly based on the results of friendly consultations between the two parties. The ultimate goal is mutual benefit and exclusive access to patent results. The above two licensing fees are all one-time patent use qualification fees charged before the implementation of patented technology. There are essential differences in the proportional distribution of patent interests between patentee and licensee in the process of cooperation with patent use. To sum up, the initial cost of a patent licensing contract mainly depends on the difficulty and cost of patent development, the benefits brought by patent implementation, the scope and duration of licensing and other factors. At the same time, the cost of exclusive license should be higher than that of ordinary license, and the payment of the fee can take different forms such as one-time payment, installment payment or cooperation with users to distribute benefits.
