equivalence principle
The principle of equivalence is a legal principle in the patent system of all countries in the world. Even if the product or method infringed by one party does not fall within the literal scope of the patent claim, it is equivalent to the invention protected by the claim, and the principle of equivalence also allows the court to determine that the party infringes the patent of the other party.
