从复审和无效案例反思药物晶型专利的创造性审查

Assessment of Inventive Step of Polymorphic Drug Patent from the Perspective of Patent Reexamination and Invalidation

文章通过梳理若干涉及药物衍生物晶型的复审和无效案例,探讨了创造性审查中最接近对比文件的选择、技术效果的确定,并结合具体案例展开分析,以期为药物衍生物晶型的专利审查提供可行性建议,从而提高专利的审查质量和授权后的稳定性。

By combing through several review processes involving patent reexamination and invalidation,this article discussed how to choose the closest prior art and the determination of technical effect,and in combination with typical cases,it is expected to provide feasible suggestions for patent examination of crystal forms of drug derivatives,thereby improving patent examination quality and stability after authorization.
