农药领域中国专利申请分析农药专利的保护类型有产品专利(包括化合物、组合物)、方法专利、用途专利。在有机化学和农药领域中国专利申请中,以农药组合物最高,国内申请占到总申请量的一半,杂环化合物和有机磷化合物国内申请大约占20%～30%,杂环化合物只有1999年、2000年国内申请量超过了总申请量的10%,其他历年均不到10%。杂环化合物农药研发国内和国外水平存在较大差距。 Pesticide Fields Analysis of Chinese Patent Applications The types of protection for pesticide patents include product patents (including compounds, compositions), method patents, and patent applications. Chinese patent applications in the fields of organic chemistry and pesticides have the highest pesticide composition, and domestic applications account for half of the total applications. Domestic applications of heterocyclic compounds and organophosphorus compounds account for about 20% -30% of the total number of applications. Heterocyclic compounds are only 1999 In 2000, the number of domestic applications exceeded 10% of the total number of applications, less than 10% of other calendar years. Heterocyclic compounds pesticide research and development at home and abroad there is a big gap between the level.
