浅议一件PCT申请优先权转让问题及引起的思考

Brief discussion on the assignment of priority right in a PCT application and the thinking aroused

简述了专利法中的优先权制度,介绍了一件PCT专利申请优先权转让问题在实质审查阶段产生的处理争议及最终的处理结论:同一专利申请人的在后申请要求其在先申请的优先权的,如果该在先申请的优先权已被转让或赠予以他人(受让人),则该申请人不能再要求享有该优先权。针对该处理结论,从民商法层面通过法律逻辑思维分析浅谈了一些见解和观点,最后基于本案问题和处理结论从专利审查或代理业务方面给出了优先权核实的建议,同时给出了在《专利审查指南》中对此问题进行明确的建议。

The paper briefly describes the priority system in Patent Law and introduces the handling dispute arising from the substantive examination stage of the priority assignment of a PCT patent application and the final conclusion:the same patent applicant claims the priority of the earlier application in a later application,and if the priority of the earlier application has been transferred or gifted to another person(assignee),then the applicant can no longer claim the priority.In view of the processing conclusion,some opinions and viewpoints are briefly discussed through the legal logical thinking analysis from the perspective of civil and commercial law.Finally,based on the problem and conclusion of this case,this paper gives suggestions of priority verification from the aspects of patent examination or agency business and suggestions for the clarification of this issue in the Guidelines for Patent Examination.
