For every international application the EPO as ISA issues either an International Search Report (ISR) or, in exceptional cases, a "Declaration of Non-Establishment of International Search Report" (see point 255), 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 220).
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 prevent a direct grant in the European phase. In any other case the WO-ISA is considered negative (see point 231).
WIPO PCT Guide 7.023
As from 1 January 2018, an information sheet ("Information on Search Strategy") is annexed to all search reports drawn up by the EPO under both the PCT and EP procedures. This information sheet contains details about the databases and keywords used by examiners to retrieve the relevant prior art, as well as the classification symbols defining the extent of the search. Information sheets are made available via file inspection on WIPO’s PATENTSCOPE and in the European Patent Register upon publication of the search report.
