66.1ter

The International Preliminary Examining Authority shall conduct a search (“top-up search”) to discover documents referred to in Rule 64 which have been published or have become available to the said Authority for search subsequent to the date on which the international search report was established, unless it considers that such a search would serve no useful purpose. If the Authority finds that any of the situations referred to in Article 34(3) or (4) or Rule 66.1(e) exists, the top-up search shall cover only those parts of the international application that are the subject of international preliminary examination.
