Equitable infringement is infringement under the principle of equivalence. If one or more features of the technical scheme accused of infringement are different from the claims, but belong to equivalent features, it constitutes equivalent infringement.
Extended data:
Judicial interpretation stipulates that the identification of equivalent features needs to meet the requirements of "basically the same function and basically the same effect by basically the same means" and "ordinary technicians in this field can associate with it without creative work" to balance the openness and equivalence principle of claims.
However, how to understand and grasp the meaning of "basic" and "ordinary" in the above provisions and reasonably identify the equivalent characteristics is the difficulty in judging equivalent infringement.
