塞尔登的专利旧案表明:如何界定专利权的保护范围是专利法上的核心问题,权利要求的解释理论堪称专利法上的一颗明珠。但是,其解释规则的复杂性及其相互之间的抵牾,使得专利权的边界具有不确定性。专利保护范围应与其技术贡献相对称,而专利法上体现权利人占有发明的公开充分性条件是衡量发明人技术贡献的重要标准。因此,以公开充分性为标准来选择专利权界定的具体规则,从而对各项具体规则予以协调,符合专利法激励创新和保护公共利益的立法精神。为了更清晰地界定专利保护范围,应该完善专利申请文件的结构,并强调普通技术人员标准在专利保护范围界定中的重要作用。
Selden’s old patent case shows that: how to define the scope of patent protection is the core issue of patent law, the claim theory of interpretation of the patent law called a pearl. However, the complexity of the rules of interpretation and the mutual opposition between them make the border of patent inflexible. The scope of patent protection should be commensurate with its technical contribution. However, the patent disclosure law, which discloses that the patent holder owns the invention, is an important criterion for measuring the technological contribution of inventors. Therefore, the specific rules defined by patent right should be chosen according to the adequacy of public disclosure so as to coordinate the specific rules and comply with the legislative spirit of patent law to encourage innovation and protect the public interest. In order to define the scope of patent protection more clearly, the structure of patent application documents should be perfected and the importance of the standard of technical staff in the definition of patent protection should be emphasized.
