Abstract World Patent Information (WPI) is the leading international academic peer reviewed journal in the field of patent information. The journal was launched in 1979 and celebrated its 40th anniversary in 2019. In recognition of this event, the aim of this work is to analyse the main actors, research themes and audiences of WPI. The analyses are based on the Scopus and Web of Science databases and include bibliographic coupling, co-citation and co-occurrence of author keywords. WPI is a boundary-spanning journal with authors from academia, industry and governmental organisations, such as patent authorities. This unique composition provides a prominent platform for knowledge transfer between academia and industry. In addition, WPI facilitates knowledge transfer between academia and industry, with research institutions citing contributions from authors affiliated to industry and patent offices. Furthermore, WPI not only crosses the boundaries between organisations (academia, industry and government), but also across disciplines, linking IP management, technology and innovation management, engineering, computer sciences, physical and natural sciences.

世界专利信息四十年：文献计量概述

摘要 World Patent Information (WPI) 是专利信息领域领先的国际学术同行评审期刊。该杂志创刊于 1979 年，并于 2019 年庆祝其成立 40 周年。为表彰这一事件，这项工作的目的是分析 WPI 的主要参与者、研究主题和受众。分析基于 Scopus 和 Web of Science 数据库，包括书目耦合、作者关键词的共引和共现。WPI 是一份跨界期刊，作者来自学术界、工业界和政府组织，例如专利当局。这种独特的组合为学术界和工业界之间的知识转移提供了一个突出的平台。此外，WPI 促进了学术界和工业界之间的知识转移，研究机构引用了附属于工业和专利局的作者的贡献。此外，WPI 不仅跨越组织（学术界、工业界和政府）之间的界限，而且跨越学科，将知识产权管理、技术和创新管理、工程、计算机科学、物理和自然科学联系起来。
