对铧式犁的全球和中国专利现状和发展趋势进行了分析,重点对全球及中国铧式犁专利申请量年度分布情况、中国申请量区域分布情况、申请人类型和申请人排名情况4个方面进行统计分析,并得出如下结论。一是铧式犁全球专利技术发展的3个阶段,分别为平稳发展期(1967年之前)、第1增长期(1968—1992年)和第2增长期(1993—2013年)。二是铧式犁中国专利技术发展的3个阶段,分别为初级发展阶段(1985—1992年)、平缓发展阶段(1993—2001年)和快速发展阶段(2002—2013年)。三是该领域中国专利申请主要以个人为主,其次是企业和科研院所,国外农机巨头未在中国形成有效的专利布局。我国企业应该抓住这个契机,增强自主创新能力,作好专利布局,在与国外企业日后的竞争中占据有利地位。
The status and development trend of plowshare patents in the world and in China are analyzed. The focus is on the annual distribution of plow patent applications in the world and in China, the regional distribution of applicants in China, the types of applicants and the ranking of applicants Statistical analysis, and draw the following conclusions. First, the plow plow global patent technology development in three stages, namely, steady development period (before 1967), the first growth period (1968-1992) and the second growth period (1993-2013). Second, the plow plow China’s patented technology development in three stages, namely, the initial stage of development (1985-1992), the flat stage of development (1993-2001) and the rapid development stage (2002-2013). Third, the main Chinese patent applications in this field are mainly individuals, followed by enterprises and research institutes. The overseas agricultural machinery giants did not form an effective patent layout in China. Chinese enterprises should seize this opportunity to enhance the capability of independent innovation, make the patent layout and occupy a favorable position in the future competition with foreign enterprises.
