摘要
目的:以药品专利组合为例,构建基于Lanjouw-Schankerman专利价值评估模型与Parchomovsky-Wag-ner专利组合理论的专利组合价值评估模型。方法:以在美国上市的82个药品的610项专利为样本,通过整合单项专利的综合专利价值指数(composite index of patent value,CIPV),进而构成专利组合价值指数(patent portfolio value index,PPVI),并与对应药品的销售额进行相关分析来检验其显著度水平。结果:CIPV值算术平均数分块加和模型最适用于专利组合价值的评估。
The paper is to develop an evaluation model of drug patent portfolio based on Lanjouw - Schankerman model and Parehomovsky - Wagner patent portfolio theory by retrieving data of 610 patent from 82 drugs marketed in USA. The paper obtains drug patent portfolio value index by integrating composite index of patent value of single patent; validates by running correlation analysis between sales and PPVI. The result shows that arithmetic separate integration model of CPIV fits patent portfolio evaluation most.
