Furthermore, the EPO as ISA will in exceptional cases not perform an international search or will perform a search limited to parts of the claimed subject-matter if the application documents fail to comply with the prescribed requirements to such an extent that a meaningful search is impossible for all or part of the claims. Applications of this kind are often referred to as "complex applications".
Before taking a decision under Article 17(2)(a)(ii) PCT, the ISA may invite the applicant informally to provide clarification of the claimed subject-matter in accordance with paragraphs 9.34 and 9.35 of the ISPE Guidelines.
