摘要/Abstract

摘要：

环烯烃聚合物[环烯烃共聚物（COC）和环烯烃均聚物（COP）]具有高耐热性、抗紫外线和耐腐蚀性等优良性能，被广泛应用于医疗、电子器件等领域。本文基于专利检索与分析，对环烯烃聚合物技术在全球范围的专利态势进行研究，分析了其技术专利申请年趋势、地域分布、申请人等，并对主要申请人的专利技术布局进行深入剖析。研究发现，自1980年茂金属催化剂问世后，相关技术快速发展，专利申请量显著增多，但日本申请人占据绝对优势，核心专利多由其掌控。技术分支中，应用类专利占比最高，催化剂和工艺次之，设备领域布局较少；在地域上，日本为专利布局核心，其次为美国和中国。结合研究结果，建议国内企业可聚焦改性、催化剂（非茂金属体系）及细分应用领域进行差异化布局，避开海外垄断技术，结合自身业务拓展应用场景。

Abstract:

Cycloolefin polymers, including cycloolefin copolymers (COC) and cycloolefin homopolymers (COP), possess excellent properties such as high heat resistance, UV resistance and corrosion resistance, making them widely applicable in fields such as healthcare and electronic devices.This study conducted a comprehensive analysis of the global patent landscape for cycloolefin polymer technology through patent retrieval and examination, focusing on application trends, geographical distribution, key applicants and their patent portfolios. The research revealed that since the introduction of metallocene catalysts in 1980, the technology had experienced rapid development with a substantial increase in patent filings. However, Japanese applicants maintain dominant control, holding most core patents. In terms of technical categories, application patents constituted the largest share, followed by catalyst and process technologies, while equipment-related patents received relatively less attention. Geographically, Japan served as the primary hub for patent activities, followed by the United States and China. Based on these findings, it was recommended that domestic enterprises adopted differentiated strategies by focusing on modification technologies, non-metallocene catalyst systems and specialized application areas to circumvent existing foreign monopolies while aligning with their core business competencies for market expansion.
