Section F‑IV, 2.1, in the Guidelines for Examination in the EPO applies mutatis mutandis.[Rule 6.3(a); GL/ISPE 5.04; ]
It is not necessary that every feature should be expressed in terms of a structural limitation. Functional features are dealt with in GL/PCT‑EPO F‑IV, 6.5. For the specific case of a functional definition of a pathological condition, see GL/PCT‑EPO F‑IV, 4.22.
