Chapter I – The right to amend
Together with the reply to the WO‑ISA, the WO-IPEA or the minutes of a telephone consultation, the applicant has, subject to certain exceptions (see GL/PCT‑EPO, C‑VII, 1(d)), the opportunity to submit (further) amendments under Art. 34 to the claims, description and/or drawings.
Subsequently filed amendments and/or arguments will be taken into account by the EPO as IPEA only if they are received before the point at which preparation of a written opinion or the IPER has actually started.
For further details, see GL/PCT‑EPO C‑IV, 1 and GL/PCT‑EPO C‑IV, 2 and subsections, and GL/PCT‑EPO C‑VII, 1.
