For each application the EPO as ISA issues both an International Search Report (ISR) or, in exceptional cases, a "declaration of non-establishment of the ISR" (see point 251) and a Written Opinion of the International Searching Authority (WO-ISA).
The WO-ISA provides the applicant with a preliminary non-binding written opinion on the question whether the claimed invention appears to be novel, to involve an inventive step and to be industrially applicable. A WO-ISA established by the EPO as ISA will be comparable to the written opinion established by the EPO for a Euro-direct application (ESOP) (see point 218).
The WO-ISA may be positive or negative. A WO-ISA is qualified as positive if it contains no objections or only minor objections which would not hinder a direct grant in the European phase. In any other case the WO-ISA is considered negative (see point 228).
