摘要

电动汽车发明过程的演变越来越复杂，因此专利丛林的可能性也越来越大。然而，专利代理人(个体发明人、公司、非执业实体和联盟)在利益和能力上并不相同。根据美国专利商标局(USPTO) 1976-2012年期间的信息，描述了以下情况:1)电动汽车发明活动日益复杂;2)代理人发明活动的特点及其演变;3)与专利丛林的关系。研究表明，专利丛的演化(从低复杂度到高复杂度)不仅与技术知识的演化有关，还与主体的演化有关。

The diversity of agents and patent thicket evolution in electric vehicles

The evolution of the inventive process in electric vehicles has been increasingly complex and thus the probability of patent thicket too. However, patent agents (individual inventors, companies, non-practicing entities and alliances) are not homogeneous in interests and abilities. Based on information from the Patent and Trademark Office (USPTO) in the period 1976-2012, it is described: 1) the growing complexity in the inventive activity of electric vehicles; 2) the characteristics and evolution in the inventive activity of agents; 3) the relation with patent thickets. It is shown that the evolution of patent thickets (from low to high complexity) is associated to the evolution of technological knowledge as well as the evolution of the agents.
