基于专利分析的稀土永磁材料产业发展研究

通过检索并分析全球稀土永磁材料相关专利，发现自20世纪90年代以来中国逐步成为第一大专利申请国。目前中国在烧结磁体的处理工艺和提升矫顽力、降低成本方面积累了一定的技术优势。但整体存在企业研发能力薄弱、原始积累不足、专利布局能力不强以及专利价值亟待提升等问题。基于此提出了技术创新与专利布局同步发力、发挥产业集聚协同优势以及完善知识产权服务体系等建议，为保障中国稀土产业高质量发展提供参考。

The Development of Rare Earth Permanent Magnet Industry Based on Patent Analysis

By retrieving and analyzing the global rare earth permanent magnet related patents, it is found that since the 90s of the 20th century, China has gradually become the largest patent applicant country. At present, China has accumulated certain technical advantages in magnets sinter process, coercivity improving and cost reduction. However, China has problems such as weak overall research and development capabilities, insufficient core technologies, weak international vision and patent layout capabilities, and urgency in patent value improvement. Based on this, suggestions are put forward such as synchronous development of technological innovation and patent layout, giving full play to the synergistic advantages of industrial agglomeration, and improving the intellectual property service system, so as to provide a reference for ensuring the high-quality development of China''s rare earth industry.
