笔者最近为一无效请求人代理了一件专利无效请求案件,在代理过程中也了解了一些与该专利的审批以及专利侵权诉讼有关的情况。该案是一个很有价值的典型案例:就程序而言,它涉及专利申请文件的撰写、审批、专利侵权诉讼、专利无效请求诸程序及各程序间的关联性;就实体而言,它除了涉及“禁止反悔”原则的适用外,还涉及对权利要求的“清楚”、“以说明书为依据”以及“功能性限定”等重要的法律规定的理解及应用。以下将对该案例作简要介绍,并分析探讨该案给我们的启示和教训。
The author recently proxied an invalid requestor for a patent invalidation request case, and also learned about the approval of the patent and patent infringement litigation in the process of agency. The case is a very valuable case in point: in terms of procedure, it involves the writing, examination and approval of patent application documents, patent infringement litigation, the procedures for the invalidation of patent claims and the interdependencies among the various procedures; in the case of an entity, it excludes Involving the application of the principle of “No estoppel”, but also involves the understanding and application of important legal provisions such as “clear”, “based on the description of the claim” and “functional limitation” of the claim. The following will make a brief introduction to the case and analyze and discuss the enlightenment and lessons from the case.
