PH4CV专利有分类编码为“800/302” 和“800/300.1”类别的专利申明的产权申明。就该分类属性,美国专利局相关文字原文是: [1] 800/302: Insect resistant plant which is transgenic or mutant。 [2] 800/300.1: The plant is maize: This subclass is indented under subclass 300. Subject matter wherein the herbicide resistant plant is maize, which is also known as corn or Zea mays. [2-1] 800/300: Herbicide resistant plant which is transgenic or mutant。 文件连接:defs800.pdf。 那文字说的很清楚,PH4CV上述类别为转基因属性,且是有抗虫和除草之功能的转基因作物属性。
