T 0039/88 (Micro-organisms) du 15.11.1988

There may be a deficiency in complying with Rule 28 EPC when the deposit of a culture of a micro-organism, originally made under other legislation, was not converted into a deposit under Rule 28 EPC or the Budapest Treaty before the filing of a European patent application. Nevertheless, due to the lack of clarity which was inherent in the system of deposits under Rule 28 in that respect, it is not justified to refuse, on this sole ground, a European patent application filed before the publication of the clarifying notice of the EPO dated 18 July 1986 concerning patent applications and European patents in which reference is made to micro-organisms (OJ EPO 1986, 269) (cf. points 4-6 of the reasons).
