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.

基于价值捕获理论的石油专利估值研究

摘要 专利技术估值是知识产权领域的研究热点。如何客观地对专利进行估值仍然是一个棘手的问题，尤其是在石油行业等产业链较长的行业。本文结合石油行业的技术特点，创新地构建了包括指标体系、指标权重计算、评分标准确定、专家评分计算在内的一整套专利价值评价体系。基于价值捕捉理论构建的模型有效地结合了传统评估方法中的成本法和收益法，避免了市场法需要的专利交易数据获取问题。采用三角模糊矩阵的计算过程增加了评价过程的客观性。本文针对八个不同的石油领域采用了不同的标准，使每种特定的专利评估模型都适用于石油行业。此外，评估过程变得相对简单且易于实施。
