4. Different texts in respect of different contracting states
Overview
In the cases discussed in H‑III, 4.2 to H‑III, 4.4, an application or a patent may contain a different set of claims (and descriptions) for different contracting states (also see G‑IV, 6). For examination and opposition proceedings, see H‑III, 4.1 to H‑III, 4.4; for limitation proceedings, see D‑X, 10.
It is not possible to have different text in respect of extension or validation states, as the relevant provisions allowing an exception to the principle of unity of the European patent application/patent relate only to EPC contracting states. However, where there are different text versions for the contracting states, the applicant may determine which one applies to the respective extension/validation state.
