Relevant claims by citation category

For ‘X’ and ‘Y’ citations, the relevant claims to which the category applies are given as prescribed in Administrative Instruction 508 (PCT/GL/ISPE/12 at paragraph 16.77).

For ‘A’ citations, it is not necessary to indicate the relevant claims unless there is good reason to do so. For example, where there is a clear lack of unity a priori and the citation is relevant only to a particular claim or group of claims. See 6.1.12.5.2 Citation Category and 6.1.4 Unity of Invention for more information.

Note: Comprehensive discussion of all cited documents in the corresponding International Search Opinion (ISO) is not required (see 6.3.8.6 Box V Reasoned Statement Regarding Novelty, Inventive Step & Industrial Applicability).

For “A” citations it is not necessary to indicate the relevant claims unless there is good reason to do so; for example where there is a clear lack of unity a priori and the citation is relevant only to a particular claim or group of claims.
