What are Article 34 Amendments in the context of international patent applications?
Article 34 Amendments are changes made to an international patent application during the international preliminary examination phase (Chapter II) under the Patent Cooperation Treaty (PCT). These amendments are filed with the International Preliminary Examining Authority (IPEA).
According to MPEP 1893.01(a)(3), “Amendments to the international application that were properly made under PCT Article 34 during the international preliminary examination phase (i.e., Chapter II) will be annexed by the International Preliminary Examining Authority to the international preliminary examination report (IPER) and communicated to the elected Offices.”
