Title of application: Primate Embryonic Stem Cells
Applicant name: Wisconsin Alumni Research Foundation
Opponent name: -
Board: 3.3.08
Headnote: The following questions are referred to the Enlarged Board of Appeal for decision:
1. Does Rule 23d(c) EPC apply to an application filed before the entry into force of the rule?
2. If the answer to question 1 is yes, does Rule 23d(c) EPC forbid the patenting of claims directed to products (here: human embryonic stem cell cultures) which - as described in the application - at the filing date could be prepared exclusively by a method which necessarily involved the destruction of the human embryos from which the said products are derived, if the said method is not part of the claims?
3. If the answer to question 1 or 2 is no, does Article 53(a) EPC forbid patenting such claims?
4. In the context of questions 2 and 3, is it of relevance that after the filing date the same products could be obtained without having to recur to a method necessarily involving the destruction of human embryos (here: eg derivation from available human embryonic cell lines)?
Relevant legal provisions:
European Patent Convention 1973 Art 53(a)
European Patent Convention 1973 Art 83
European Patent Convention 1973 Art 112(1)(a)
European Patent Convention 1973 R 23d
Keywords: Human embryonic stem cell culture - sufficiency of disclosure (yes)
