4.1 Matter contrary to public order or morality 

Unlike the EPC, the PCT does not explicitly rule out the patentability of subject-matter for reasons of public order or morality. However, according to Rule 9, the application must not contain any expressions contrary to public order or morality, and under the Agreement between the EPO and WIPO the EPO may exclude matter which would be excluded under Art. 53(a) EPC. Generally, no search or preliminary examination is carried out on such matter by the EPO as ISA/IPEA. Section G‑II, 4.1, in the Guidelines for Examination in the EPO applies mutatis mutandis.
