摘要：

精密锻造是大国间较量的必争之技，以22035件全球专利为依据，分析了该技术的全球专利布局及技术发展。全球精密锻造技术专利整体呈现快速上涨趋势，技术周期处于技术成长期；中国是最大的目标市场、最多的原创专利来源国；美国专利申请人的全球布局意识最强，原创专利流向全球的范围最广；技术结构主要集中在IPC小类B21J、B21K和C22C等，中国覆盖的技术领域范围最广，优势领域在F16P、B08B等，F02B存在短板；日本企业的研发实力最强、高价值专利数量最多。我国应优化专利结构、提高专利质量，增强全球布局，扩大重点技术领域的领先优势，补齐技术短板，提高专利技术的成果化、资本化和产业化。

Precision forging is a competitive technology among major countries. Therefore, based on 22035 global patents, the global patent layout and technology development of this technology were analyzed. The global precision forging technology patents are showing a rapid upward trend as a whole, and the technology cycle is in the period of technological growth. China is the largest target market and the source courtry of the most original patents. American patent applicants have the strongest global layout awareness and the widest range of original patents flowing to the world. The technical structure is mainly concentrated in IPC subcategories such as B21J, B21K and C22C, etc., and China has the widest coverage range in the field of technology, with advantages in F16P, B08B and so on, while shortcomings in F02B. Japanese companies have the strongest research and development capabilities and the largest number of high-value patents. Thus, China should optimize the patent structure, improve the quality of patents, enhance the global layout, expand the leading advantages in key technological fields, make up for the shortcomings of technology, and improve the achievement, capitalization and industrialization of patent technology.
