EPO Enlarged Appeal Board decision in G 0003/08 Programs for computers/PRESIDENT’S REFERENCE
The EPO President asked the Enlarged Board to consider a set of questions concerning the patentability of programs for computers (computer-implemented inventions, CIIs) on which she deemed the Boards of Appeal to have given different decisions and which she held to be of fundamental importance within the meaning of a. 112(1) EPC. Her referral had been preceded by an informal letter from her predecessor, Alain Pompidou, dated 22 February 2007, in which Lord Justice Jacob's suggestion in theAerotel/Macrossanjudgment of 27 October 2006 ( EWCA Civ 1371) of referring the issue of CII patentability to the Enlarged Board had been dismissed as unnecessary. About 100Amicus curiaebriefs had been filed, amongst which a number questioned the admissibility of the referral, a view which was supportedinter aliaby Lord Hoffmann who was until his recent retirement the member of the UK House of Lords Judicial Committee who usually wrote the opinion of the House in cases involving IP.
The opinion of the Enlarged Board is available here.
and a more extended file of the case including the questions originally referred and the reasons for the reference can be found here.
In the outcome, the doubts proved well-founded and the referral was rejected as inadmissible. The views of the Enlarged Board are summarised in the official headnote:
“1. In exercising his or her right of referral a President of the EPO is entitled to make full use of the discretion granted by Article 112 (1) (b) EPC, even if his or her appreciation of the need for a referral has changed after a relatively short time.
2. Different decisions by a single Technical Board of Appeal in differing compositions may be the basis of an admissible referral by the President of the EPO of a point of law to the Enlarged Board of Appeal pursuant to Article 112 (1) (b) EPC.
3. As the wording of Article 112 (1) (b) EPC is not clear with respect to the meaning of “different/abweichende/divergent” decisions the provision has to be interpreted in the light of its object and purpose according to Article 31 of the Vienna Convention on the Law of Treaties (VCLT). The purpose of the referral right under 112 (1) (b) EPC is toestablish uniformity of law within the European patent system. Having regard to this purpose of the presidentialright to refer legal questions to the Enlarged Board of Appeal the notion “different decisions” has to be understoodrestrictively in the sense of “conflicting decisions”.
4. The notion of legal development is an additional factor which must be carefully considered when interpreting thenotion of “different decision” in Article 112 (1) (b) EPC. Development of the law is an essential aspect of its application, whatever method of interpretation is applied, and is therefore inherent in all judicial activity. Consequently, legal development as such cannot on its own form the basis for a referral, only because case law in new legal and/or technical fields does not always develop in linear fashion, and earlier approaches may be abandoned or modified.
5. Legal rulings are characterised not by their verdicts, but by their grounds. The Enlarged Board of Appeal may thustakeobiter dictainto account in examining whether two decisions satisfy the requirements of Article 112 (1) (b) EPC.
6. T 0424/03,Microsoftdoes deviate from a view expressed in T 1173/97,IBM, concerning whether a claim to a program on a computer-readable medium necessarily avoids exclusion from patentability under Article 52(2) EPC. However this is a legitimate development of the case law and there is no divergence which would make the referral of this point to the Enlarged Board of Appeal by the President admissible.
7. The Enlarged Board of Appeal cannot identify any other inconsistencies between the grounds of the decisions which the referral by the President alleges are divergent. The referral is therefore inadmissible under Article 112(1)(b) EPC.”
As regards the relationship between excluded subject mater and inventive step, the Enlarged Board concluded:
“Indeed if the Boards continue to follow the precepts of T 1173/97IBMit follows that a claim to a computer implemented method or a computer program on a computer-readable storage medium will never fall within the exclusion of claimed subject-matter under Articles 52(2) and (3) EPC, just as a claim to a picture on a cup will also never fall under this exclusion. However, this does not mean that the list of subject-matters in Article 52(2) EPC (including in particular "programs for computers") has no effect on such claims. An elaborate system for taking that effect into account in the assessment of whether there is an inventive step has been developed, as laid out in T 154/04,Duns. While it is not the task of the Enlarged Board in this Opinion to judge whether this system is correct, since none of the questions put relate directly to its use, it is evident from its frequent use in decisions of the Boards of Appeal that the list of "non-inventions" in Article 52(2) EPC can play a very important role in determining whether claimed subject-matter is inventive … It would appear that the case law, as summarised in T 154/04, has created a practicable system for delimiting the innovations for which a patent may be granted.”
The Enlarged Board did not attempt ant definition of technical effect, but commented:
“While the referral has not actually identified a divergence in the case law, there is at least the potential for confusion, arising from the assumption that any technical considerations are sufficient to confer technical character on claimed subject-matter, a position which was apparently adopted in some cases (e.g. T 769/92,Sohei, Headnote 1). However T 1173/97,IBMsets the barrier higher in the case of computer programs. It argues that all computer programs have technical effects, since for example when different programs are executed they cause different electrical currents to circulate in the computer they run on. However such technical effects are not sufficient to confer "technical character" on the programs; they must cause further technical effects. In the same way, it seems to this Board, although it may be said that all computer programming involves technical considerations since it is concerned with defining a method which can be carried out by a machine, that in itself is not enough to demonstrate that the program which results from the programming has technical character; the programmer must have had technical considerations beyond "merely" finding a computer algorithm to carry out some procedure.”
The fine print of the opinion will attract obsessive attention from specialists in this area, but the bottom line for the time being is that the status quo will be maintained. European practitioners await theBilskidecision with, if anything, even more interest.
