我国农药新化合物创制工作经过近30年的发展,已有30多个自主研发的农药产品取得了专利保护,但是目前农药市场上的重要专利产品基本上都为国外农药公司所有。随着跨国公司越来越多的农药专利到期或失效,因此如何合理利用专利失效的农药产品已经成为企业急需解决的热点问题……我国《专利法》于1985年实施,由于当时我国化学领域的科技研发水平比较落后,创制产品极少,而国外在新农药创制产品上占据绝对优势。为了给我国化学产品的研制从起步时期,或者说从仿制时期向创制时期提供过渡,《专利法》第25条规定,对食品、饮料、调味品、药品以及用化学方法获得的物 After nearly 30 years of development of new pesticide compounds in China, more than 30 proprietary pesticide products have been patented, but at present, all the important patented products in the pesticide market are basically owned by foreign pesticide companies. As more and more pesticide patents of multinational corporations expire or expire, how to make rational use of patent-invalidated pesticide products has become a hot issue urgently needed by enterprises ... Our Patent Law came into force in 1985, R & D level of technology is relatively backward, the creation of very few products, and abroad in the new pesticide products to create an absolute advantage. In order to make the development of chemical products in our country from the initial stage or from the imitation period to the creation period, Article 25 of the Patent Law stipulates that food, beverage, condiment, medicine and chemical substances
