摘要
Abstract
This paper firstly constructs an indicator system to assess core patent through literature research method. And then many patent portfolio analysis methods such as highly cited, co-citation and patent family are used to identify the core patents of international fuel cell vehicles. On this basis, we evaluate them in multiple angles, major patentees, IPC, patent family, patent life, for instance. Finally, we confirm that the core patents of international fuel cell vehicles mainly concentrate in the following three fields:fuel cell engine systems, ve-hicle integration layout and fuel cell technology.关键词
