目的:探讨心脑血管中药复方专利维持的影响因素。方法:运用logistic回归分析方法考察专利维持有效的影响因子。结果:心脑血管中药复方专利的维持与其发明本身、专利权转让、权利要求、专利申报文件关系密切。结论:心脑血管中药复方授权专利维持有效的比例较小,专利组方药物功效集中化、从属权利要求数量增加、提供新剂型及详实的实验数据有利于提升专利质量进而维持专利有效,专利权的转让对于专利的维持具有重要意义。
Objective: To investigate the factors that influence the maintenance of TCM patents of cardiovascular and cerebrovascular. Methods: Logistic regression analysis was used to examine the influencing factors of patent maintenance. Results: The maintenance of cardiovascular and cerebrovascular medicine compound patent was closely related to the invention itself, the transfer of patent rights, the claims and the patent application documents. CONCLUSION: The proportion of cardiopulmonary and cerebrovascular traditional Chinese medicine compounding patents is small, the efficacy of patent group is centralized, the number of subordinate claims is increased, new dosage forms and detailed experimental data are helpful to improve the patent quality and maintain the patent’s validity. The transfer of patents for the maintenance of great significance.
