Zhao Hongping: the significance of patent search in new drug research

On November 18, Zhao Hongping, associate professor of China Pharmaceutical University, held the "China (Nanjing) 2015 pharmaceutical information access and utilization forum" jointly held by yaozhi.com, China Pharmaceutical University and the editorial board of pharmaceutical progress Zhao Hongping, associate professor of China Pharmaceutical University, shared the following issues related to patent retrieval of new drug project initiation and research Zhao Hongping said that patent search is of great significance in the process of new drug project investigation The sound patent search work can avoid repeated research and patent infringement, protect scientific and technological innovation, implement patent strategy, improve the innovation and competitiveness of enterprises, so as to achieve patent mining and easily deal with disputes In terms of the period of protection of drug patents, he said that most countries did not expire until 20 years after the date of patent application being authorized and announced In the United States, the patent protection of drugs approved by FDA can be extended for 5 years, but not more than 14 years after the date of product listing Since January 2, 1993, the European community has stipulated that if the period of patent protection is less than 15 years, it can be extended for 5 years after obtaining the production license from the relevant health department Japan, like the United States, can extend for up to five years Zhao Hongping said that there are many characteristics of drug patent retrieval that need to be noted, such as the complexity and variety of drug names, incomplete name enumeration, which is easy to cause missed detection; it is necessary to rely on specialized retrieval methods such as chemical structure, gene sequence, etc.; molecular retrieval may not be able to accurately locate In addition, Zhao Hongping also described the strategy of drug patent search in detail in the report For the patent of preparation method, in addition to the search of preparation method, it is also necessary to search the compound patent comprehensively to avoid infringement; for the patent of pharmaceutical composition, it is necessary to search the drug combination and preparation patent simultaneously; for the patent of pharmaceutical dosage form, in addition to the specific dosage form, it is necessary to deal with relevant issues In order to ensure the competitiveness of technology, it is necessary to conduct a comprehensive search of the pharmaceutical form patent; for the determination of the protection area, it is necessary to conduct a comprehensive search of the family patent and legal status, and determine the geographical blank area for patent protection Finally, Zhao Hongping introduced the retrieval tools needed in the process of patent retrieval in detail, which are: Official Websites of patent offices of various countries, large-scale international commercial online retrieval system, patent search engine, public welfare free patent database website, common retrieval database, famous patent package download website.
