Abstract

Patents are one of the most widely used tools to analyze environmental technologies. Organizations such as the World Intellectual Property Organization and OECD have developed search strategies to retrieve green patents based on their patent classification. These classifications divide patents into clusters, which are aligned with different sustainability goals. In this paper, we take advantage of this to analyze the distribution of patents across 1.221 patent classes within six clusters defined by OECD's ENV-TECH classification. We also assess the maturity stage of each patent class by fitting two commonly used S-curve models, namely logistic and Gompertz. We find that (a) most patent classes are still in a relatively early stage of the technology life cycle and (b) considerable heterogeneity exists in the distribution of patents, both within and across clusters. We discuss the methodological implications of our results and provide recommendations for scholars, drawing on green patent analyses, to conduct future work on environmental technologies.

绿色专利集群的成熟度评估：方法论意义

专利是分析环境技术最广泛使用的工具之一。世界知识产权组织和经合组织等组织已经制定了检索策略，根据专利分类检索绿色专利。这些分类法将专利分为多个群组，这些群组与不同的可持续发展目标相一致。在本文中，我们利用这一优势分析了经合组织 ENV-TECH 分类所定义的六个群组中 1.221 个专利类别的专利分布情况。我们还通过拟合两种常用的 S 曲线模型（即逻辑模型和 Gompertz 模型）来评估每个专利类别所处的成熟阶段。我们发现：(a) 大部分专利类别仍处于技术生命周期的相对早期阶段；(b) 专利分布存在相当大的异质性，无论是在集群内部还是在集群之间。我们讨论了研究结果的方法论意义，并为学者们借鉴绿色专利分析方法今后开展环境技术研究提供了建议。
