基于专利组合的电动汽车企业研发优势和商业机会评估

Evaluation of R&D Advantages and Business Opportunities for Electric Vehicle Industry Based on Patent Portfolio

近年来,作为汽车产业的一个发展方向,电动汽车的发展迎来了前所未有的新契机。在这强者鼎立的格局中已有多家企业在一些关键技术上有所突破,比如特斯拉和丰田都在电池及其管理技术领域有较强优势。本文以Ernst教授的专利组合理论为基础,对其专利组合方法进行部分修正,利用专利技术规模、相对技术优势和相对技术融合能力指标代替专利申请量、专利授权率、IPC号数量、专利被引量等指标,对全球电动汽车企业的研发优势及其商业机会进行评估。研究结论可对明确电动汽车技术的重点研发领域以及各电动汽车企业的研发优势,进而为我国电动汽车企业研发投资方向和合作伙伴的选择提供决策依据。

Since recently, as a development trend of auto industry, electric vehicles is ushered in the unprecedented new opportunity. In this situation of the tripartite confrontation of the strong, a bunch of companies has achieved the breakthroughs on some key technologies, especially, battery and management technology of Tesla and TOYOTA are superior to others. Based on Professor Ernst＇s patent portfolio theory as well as a partial modification of the patent portfolio method, the R＆D advantages and the business opportunities of the global electric vehicle industry are evaluated in this paper by the technology scale, relative technology advantage, and relative technology integration capability, instead of the number of patent applications, the number of the patent granted patents, the number of IPC classes, the patent citation frequency, etc. The research conclusion will clarify the key R＆D fields and strengths, and provide theories and data for business decisions on R＆D investment and collaborators for electric vehicle enterprises in China.
