摘　　要：利用中国国家知识产权局专利检索系统和上海知识产权信息平台,收集、整理、分类了1985-2016年公开的稀土钢领域的中国专利。对专利申请趋势、专利区域分布状况、专利法律状态分布、专利申请人和发明人、专利技术领域等要素进行了分析。结果显示,稀土钢专利总体数量较少,但自2005年以后快速、持续增长;国内企业和机构占据了中国专利申请的绝大部分,国外机构申请量极少;无效专利比例较大,专利申请技术有待提高。建议加强稀土钢技术的研发力度,提高知识产权保护的专业化水平。The patent applications in China in rare earth steel from 1985 to 2016 were collected, arranged and classified by using the patent retrieval system of the State Intellctual Property Office of the P. R. C and The Shanghai Intellectual Property Information Platform. The trend of the patent applications, patent distribution at home and abroad, distribution of patent legislation, patent applicant and inventor and technology field were analyzed. The results indicated that the patent applications in rare earth steel are small, but it has increased quickly and steadily since 2005. Domestic organizations applied the most part of the patent applications. There were large amount of invalid patents, because the patent application skill is not good enough. It is suggested that the study of rare earth steel should be strengthened, and the specialization of intellectual property protection should be improved.
