ABSTRACT

The pricing of patents is a complex mathematical problem, which involves many aspects of scientific research, economy, society, etc. There are many traditional pricing models. Some models are based on artificial scoring, and some models are difficult to obtain parameter data. This paper proposes the Monte Carlo cut difference method to solve the problem of patent pricing based on the shortcomings of these models. Aiming at the issue of patent pricing, this article uses variables to represent the economic factors related to patents, such as technical dimensions and legal dimensions, and then gives the impact of each parameter on the company’s expenditure and income, and abstracts the process into a mathematical model This model shows the amount of change in the market value of the company before and after the patent is purchased. This amount of change is used to express the value of the patent. This model is called the gap model. Because the calculation of the gap model is very complicated, this article introduces the Monte Carlo method to calculate the model, uses a computer to simulate the actual operating process of the company (mainly including income and expenditure), and uses the simulation results to replace the real values. We collected relevant data on the Internet and used the Monte Carlo cut model to estimate the value of a certain electronic equipment patent and a daily chemical patent. The results were 1,671,400 yuan and 153,507 million yuan respectively. Finally, based on the model and calculation results, a proposal was written to relevant departments.
