我国专利侵权中可预见性规则司法适用问题研究

Research on the Issues of Judicial Application of Foreseeability Principle in Patent Infringement in China

可预见性规则要求专利申请人在申请专利时将当时可以预见到的所有等同物写进权利要求书中,否则嗣后不得通过等同原则将其涵盖到权利要求保护的范围之内。可预见性规则虽然具有使专利权人的权利边界更加清晰的功能,但该规则对等同原则限制过度,与我国当前鼓励研发与投资高价值发明专利的产业政策相违背,且不具有现实可行性。因此,我国在司法实践中能否适用可预见性规则仍有待进一步研究。

The foreseeability principle requires patent applicants to include all equivalents that can be foreseen at the time of filing a patent in the claims, otherwise they may not be covered by the principle of equivalence. Although the foreseeability principle has the function of making the rights boundary of the patentee clearer, the rule is too restrictive to the principle of equality, which is contrary to the current industrial policy of encouraging R&D and investment of high-value invention patents in China, and it has no practical feasibility. Therefore, whether the application of the foreseeability principle in China's judicial practice remains to be further studied.
