Research on petroleum patent valuation based on Value Capture Theory

Abstract

The valuation of patent technology is a research hotspot in the area of intellectual property. How to objectively value a patent is still a thorny issue, especially in industries with long industry chains like the petroleum industry. This paper combines with the technical characteristics of the petroleum industry, builds up a set of patent value evaluation systems including the index system, the calculation of indicator weights, the determination of scoring criteria, and the expert score calculation innovatively. The model constructed based on the Value Capture Theory effectively combines the cost method and the benefit method in traditional assessment methods, avoiding the problem of obtaining the patent transaction data that market method required. The calculating process which adopts triangle fuzzy matrix increases the objectivity of the evaluation process. Different criteria for eight different fields of petroleum are applied in this paper, which make each specific patent evaluation model suitable for the petroleum industry. In addition, the process of evaluation becomes relatively simple and easy to implement.
