I. 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.
II. Different decisions by a single tech- nical board of appeal in differing compo- sitions 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.
referral right under Article 112(1)(b) EPC is to establish uniformity of law within the European patent system. Having regard to this purpose of the presidential right to refer legal questions to the Enlarged Board of Appeal the notion "different decisions" has to be understood restrictively in the sense of "conflicting decisions".
IV. The notion of legal development is an additional factor which must be carefully considered when interpreting the notion of "different decision" in Article 112(1)(b) EPC. Development of the law is an essential aspect of its application, what- ever method of interpretation is applied, and is therefore inherent in all judicial activity. Consequently, legal develop- ment 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.
V. Legal rulings are characterised not by their verdicts, but by their grounds. The Enlarged Board of Appeal may thus take obiter dicta into account in examining whether two decisions satisfy the requirements of Article 112(1)(b) EPC.
VI. T 424/03, Microsoft does deviate from a view expressed in T 1173/97, IBM, concerning whether a claim to a program on a computer-readable medium neces- sarily 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.
VII. 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.
I. In a referral under Article 112(1)(b) EPC dated 22 October 2008, the Presi- dent of the EPO asked the Enlarged Board of Appeal 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 import- ance within the meaning of Article 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 the Aerotel/Macrossan judgment of 27 October 2006 ( EWCA Civ 1371) of referring the issue of CII patentability to the Enlarged Board was dismissed as unnecessary.
9 were from other sources; of these, 6 were from individuals.
II.2 The question of the admissibility of the referral was raised in approximately a quarter of the submissions, mainly by lawyers or non-FOSS industry. Of these the great majority either expressed "doubts" about the admissibility or argued that the referral was definitely not admissible.
Three quarters of the submissions gave responses to some or all of the individual questions of the referral. However in many if not most cases these responses took the form of comments or observa- tions, rather than answers classifiable as "yes" or "no". For this reason the Enlarged Board will not attempt to present a statistical analysis of the responses to the questions.
Around one third of all of the submis- sions made an analysis of the case law of the Boards of Appeal of the EPO. Most of the rest relied on either national (including US) case law, gave their views on how the EPC ought to be interpreted, or made general statements based on policy considerations.
inventions. Perhaps surprisingly there was very little correlation between this 30% and the submissions which argued that the referral was inadmissible.
II.4 One of the amici curiae argued that the Enlarged Board, and more specifi- cally one of its members, was not impar- tial. The Board applied Article 4(1) of the Rules of Procedure of the Enlarged Board of Appeal and Article 24(4) EPC. In a composition not including the affected member the Enlarged Board deliberated and issued an interlocutory decision dated 16 October 2009 that the original composition was to remain unchanged.
Admissibility of the referral 1. Under Article 112(1)(b) EPC, in order to ensure uniform application of the law, or if a point of law of fundamental import- ance arises, the President of the EPO may refer a point of law to the Enlarged Board of Appeal where two Boards of Appeal have given different decisions on that question.
2. The first issue the present case raises is whether the President's referral might be inadmissible on the grounds that her predecessor had declined to refer CII patentability issues to the Enlarged Board only the year before, in his letter of 22 February 2007 to Lord Justice Jacob. In other words, if no further decisions throwing new light on the issues had been taken in the interim, the question arises whether the presidential right of referral might have been forfeited.
Appeal has changed and he therefore finds the implications of a perceived divergence more significant for Office practice than he initially thought. Or, as is the case here, a change in the presidency has taken place and the new President views matters differently from his predecessor. Therefore, in the present case the right of referral cannot be held to have been lost.
(ii) two Boards of Appeal have given different decisions on the questions referred.
4. As regards the first admissibility criterion, which must be met for every referral whether from a Board of Appeal under Article 112(1)(a) EPC or from the President under Article 112(1)(b) EPC, the President maintains that the referral concerns the application of the exclusion of computer programs as such and is therefore of fundamental importance.
tive (COM (2002) 92 final 2002/0047 (COD)). A uniform understanding of where to draw the dividing line between applications relating to programs for computers as such, which are excluded from patentability under Article 52(2)(c) and (3) EPC, and applications relating to patentable technical solutions, in the form of CIIs, still cannot be assumed despite considerable convergence in recent court rulings.
4.2 Given the economic significance of such inventions in many technical fields, plus the consequent heated public debate on their patentability and the many cases before the EPO's Technical Boards and various national courts, the fundamental importance of the general subject addressed by the questions referred is not open to serious doubt.
5. Of course, the fact that there is such a worldwide debate does not mean that there have necessarily been different decisions taken by two Boards of Appeal within the meaning of Article 112(1)(b) EPC. It is clear from the wording of that article that decisions of other (national) courts are not relevant when examining the admissibility of a referral. Such courts are not part of the European Patent Organisation, and there is nothing in the EPC to make their decisions binding on the Office.
6. As to what is meant by different decisions of two EPO Boards of Appeal, this may depend on whether, as in the present case, the decisions cited as the basis for the referral were taken within the competence of a single Board of Appeal in differing compositions. It might be thought, not unreasonably, that this does not comply with the wording of Article 112(1)(b) EPC, which would make the admissibility of a presidential referral dependent on differences in the rulings of two Boards of Appeal.
members of the Boards of Appeal (with the exception of the legally qualified chairmen of the Technical Boards of Appeal) and which therefore sits in a number of different compositions. In this context, it is noteworthy that the EPC does not define the Legal Board of Appeal as an organisational unit, but only by its composition, which lends additional strength to the argument that different decisions of that board may be the basis of a referral by the President of the EPO, at least if taken in different compositions. As this is the case here, there is no need to discuss whether a referral by the President of the EPO would also be admissible had the Legal Board of Appeal handed down different decisions in the same composition. Likewise, no opinion is to be expressed on the admissibility of a referral, had the present situation arisen not in the Legal Board of Appeal but in one of the Technical Boards of Appeal. Finally, no discussion is necessary on the limitation of the power of referral by the President of the EPO by the power of the Legal Board of Appeal to develop its case law by abandoning former case law (cf. Singer/Stauder, loc. cit.). In the present case, there is no evidence at all that this was intended by J 22/95. On the contrary, in point 7.2 of the Reasons, it is stated that there "are no conflicting decisions relevant to this case ..." (Reasons, point 1.2, second paragraph).
of the law within the Organisation in the interest of legal certainty. Lack of uniform application which warrants a referral may also happen within a single Board as an organisational unit, no matter whether legal or technical, and therefore no distinction should be made between the Legal Board of Appeal (case G 4/98) and a Technical Board of Appeal. It would be too limiting to declare a referral by the President inadmissible simply because the formal requirement that two Boards of Appeal must be involved has not been fulfilled. At least this holds true when, as is the case here, the Board of Appeal has delivered the allegedly different decisions in different compositions (see also Joos in: Singer/Stauder, The Euro- pean Patent Convention, 5th edition, 2010, Article 112 marginal number 25). The question what the situation would be had the Board of Appeal delivered the allegedly different decisions in the same composition needs not to be answered here. Of course, to hold the referral admissible in respect of who delivered the allegedly different decisions does not mean that it has passed the admissibility test altogether. For this, it is necessary that the Board in question has indeed given "different decisions" within the meaning of Article 112(1)(b) EPC. This will be examined below.
matter? How do different decisions relate to other case law of the Boards?
7.1 The meaning to be assigned to the key term "different decisions" as this expression is used in Article 112(1)(b) EPC must initially be determined on the basis of the provision's wording in all official versions of the EPC, these all having equal status (Article 177(1) EPC). Yet the wording does not seem to give a clear answer. The English, German and French terms used ("different", "abwei- chend" and "divergent" respectively) do not appear to have entirely the same connotations. Cassell's English-German Dictionary, 1978 edition, translates "different" with German words such as "anders, verschieden, andersartig, abweichend, ungleich, verschiedenartig", whereas according to Harrap's Shorter Dictionary French-English (1988 Reprint) the French term "divergent" equates to "divergent" in English, not "different", and in German is according to Larousse Grand Dictionnaire Allemand- Franais, 1999 edition, equivalent to terms like "divergierend, auseinanderlaufend, abweichend". This results in variations in semantic content (abweichend/different/ divergent) between the three language versions. "Different decisions" could apparently be ones that are far apart in time, regardless of whether they actually still have a claim to validity in view of intervening changes in case law. "Divergent decisions" by contrast would suggest ones which do not take the same line, which in other words vary in their substantive content, while being close together in time. Thus a clear answer cannot be derived from the wording of the provision alone.
Treaties (VCLT) whose rules for the interpretation of treaties are to be applied to the EPC (see G 5/83, OJ EPO 1985, 64, Reasons, point 3 ff.; G 2/02 and 3/02, OJ EPO 2004, 483, Reasons, point 5.2 ff.; G 1/07 dated 15 February 2010, Reasons, point 3.1; G 2/08 dated 19 February 2010, Reasons, point 4)), and if we consider the object and purpose of Article 112(1)(b) EPC in the context of the EPC, there is much to suggest that it means divergent deci- sions in the second sense mentioned in paragraph (a) above (on the Enlarged Board's approach to interpretation see Schachenmann, Die Methoden der Rechtsfindung der Groen Beschwerde- kammer, GRUR Int. 2008, 702/704 ff.; Stauder in: Singer/Stauder, Euro- pisches Patentbereinkommen, 5th edition, 2010, Art. 177 passim with further indications).
7.2.1 According to current constitutional thinking, the predictability and verifiability of all state action are indispensable elements of a democratic legal order based on the separation of powers, the rule of law and respect for human rights including fundamental procedural rights. These principles have been subscribed to in substance at national level by all the EPC contracting states, despite differing constitutional traditions and despite several reservations made by different states. As a democracy is prohibited from signing an international treaty which would undermine its citi- zens' constitutional guarantees, the EPO must therefore support these funda- mental principles either explicitly (e.g. Art. 113 EPC) or implicitly (e.g. liberty, equality) (see for example G 3/98, OJ EPO 2001, 62, Reasons, point 2.5.3; G 2/02 and G 3/02, Reasons, point 7.2; T 377/95, OJ EPO 1999, 11, Reasons, points 33-36; T 1193/02 dated 18 March 2005, Reasons, point 10; T 190/03, OJ EPO 2006, 502, Reasons, point 10).
The European Patent Organisation is an international, intergovernmental organi- sation, modelled on a modern state order and based on the separation of powers principle, which the sovereign contracting states have entrusted with the exercise of some of their national powers in the field of patents. Thus the EPC assigns executive power to the Office to grant patents and to its Presi- dent to manage the Office in organ- isational respects (Articles 4(3) and 10 ff. EPC), while to the Administrative Council it assigns limited legislative powers restricted to lower-ranking rules (Article 33 EPC), along with financial and supervisory powers. Finally, the Boards of Appeal, which in their decisions are bound only by the EPC (Article 23(3) EPC), are assigned the role of an inde- pendent judiciary in this patent system (Articles 21 to 23 EPC; see also G 6/95, OJ EPO 1996, 649, Reasons, points 2 ff.), even if for the present, pursuant to Article 4(2) EPC and to EPC Part 1 Chapter III, they are not an independent organ of the Organisation but structurally integrated departments of the Office under Article 15 EPC.
7.2.2 Like the judiciary of any democratic entity based on the separation of powers principle, the EPO's Boards of Appeal as an independent judiciary guarantee the due process of law within the Organisa- tion. They are also assigned interpreta- tive supremacy with regard to the EPC in terms of its scope of application (see also Article 23(3) EPC). Under Article 21(1) EPC they are responsible for reviewing decisions taken by the Office in grant and opposition proceed- ings. Their interpretation of the EPC is the basis for the practice established by the Office for the examination of patent applications and oppositions to granted patents. Otherwise there would be no need for the President's right of referral.
mean that in interpreting the Convention the Boards of Appeal should not take account of relevant national decisions on harmonised European patent law, in keeping with normal practice. This is implied by the harmonisation philosophy behind the EPC.
7.2.3 Another essential element of a democratic legal order is the principle that a public authority is bound by law and justice. This is supplemented by the principle of uniform application of the law. Both principles are designed to ensure predictability of jurisdiction and hence legal certainty by preventing arbi- trariness. Those subject to the law, in the case of the EPC the parties to proceed- ings before the Office, but also the public, must be able to expect that the Office as patent granting authority and consequently the Boards of Appeal will settle cases of the same nature in the same way and will apply comprehensible arguments and methods to justify any substantive differences in such deci- sions. For the stated reasons, these prin- ciples also constitute essential precepts for administration and jurisdiction in the European patent system as codified in the EPC. Ensuring compliance with them is ultimately the task of the Boards of Appeal, including the Enlarged Board, the latter though only in the context of referrals by the Boards of Appeal and the President under Article 112(1) EPC and concerning petitions for review (Article 112a EPC).
two Boards of Appeal must have given different decisions on the question referred. Hence the Enlarged Board does not rule on abstract points of law, but only ever on real issues arising from the cited differing decisions, as well as on specific legal questions adduced in the referral (see Moser in: Europisches Patentbereinkommen, Mnchner Gemeinschaftskommentar, 20th issue 1997, Article 112, marginal number 28; van Empel, The Granting of European Patents, 1975, marginal number 524). It is to be noticed that the President is not a party in a referral procedure because she or he cannot be adversely affected by answers given by the Enlarged Board.
7.2.5 Thus it is clear that the interpret- ation of the EPC is primarily the respon- sibility of the Boards of Appeal. As a rule they have interpretative supremacy with regard to the EPC because their decisions are subject to review only under the narrowly defined conditions of Article 112(1) and 112a(2) EPC. It is only when these apply that the Enlarged Board has the last word. The fact that the Enlarged Board takes action only on a referral from the Boards of Appeal or the President (with the exception of peti- tions for review under Article 112a EPC, which however concern procedural matters and have a very narrow scope) and thus does not constitute a further instance ranking above the Boards of Appeal within the EPC judicial system is a clear indication of the extent of its significance for legal uniformity. The exhaustive list of admissibility criteria for a referral under Articles 112(1)(a) and (b) EPC implies that the Enlarged Board takes decisions on specific legal ques- tions and that neither the Boards of Appeal nor the President are authorised to consult it whenever they so wish in order to clarify abstract points of law. For that purpose the President can call upon a separate Legal Department within the Office.
7.2.6 On the same restrictive grounds, Article 112(1)(b) EPC as an additional constraint for a referral by the President as opposed to one by a Board of Appeal requires there to be differences in the rulings of two Boards of Appeal (in the sense already discussed) on a point of law. The "different decisions" criterion would appear to show that the President is only intended to be allowed to refer a question to the Enlarged Board when there is a divergence or, better, conflict in the case law making it difficult if not impossible for the Office to bring its patent granting practice into line with the case law of the Boards of Appeal. It is of course immaterial whether the initiative behind the referral comes from a third party, as long as there is objective evidence of divergent applications of the law.
7.2.7 Given its object and purpose, the right of referral does not extend to allowing the President, for whatever reason, to use an Enlarged Board referral as a means of replacing Board of Appeal rulings on CII patentability with the decision of a putatively higher instance. For example, a presidential referral is not admissible merely because the European Parliament and Council have failed to adopt a directive on CII patenting or because consistent Board rulings are called into question by a vocal lobby (cf. the present referral, page 2, Section 1, paragraph 3). Even the essentially commendable desire for harmonisation expressed by Lord Justice Jacob in the Aerotel/Macrossan judgment can be taken up by the Enlarged Board only to the extent possible under the EPC, even if his suggestion might significantly advance the cause of legal uniformity in Europe. When judiciary-driven legal development meets its limits, it is time for the legislator to take over.
7.3 The notion of legal development is an additional factor which must be carefully considered when interpreting the notion of "different decisions" in Article 112(1)(b) EPC, as has occasion- ally been pointed out in the literature (e.g. Teschemacher, Der Beitrag des Prsidenten des Europischen Patent- amts zur Rechtsprechung der Groen Beschwerdekammer eine erste Bestandsaufnahme, GRUR 1993, 320/326 f.) and various amicus curiae briefs.
7.3.1 Development of the law is an essential aspect of its application, what- ever method of interpretation the judge applies, and is therefore inherent in all judicial activity. In that light an element of legal development can even be seen whenever a specific case is subsumed under an abstract regulation. That is especially true of Anglo-Saxon law, where a decision on an individual case has far greater implications as a prece- dent than judgments in continental civil law. Consequently, legal development as such cannot on its own form the basis for a referral, only because case law in new legal territory does not always develop in linear fashion, and earlier approaches may be abandoned or modified.
Otherwise the "different decisions" feature of Article 112(1)(b) EPC would lose its meaning. While the development of the law may superficially appear to give rise to different decisions within the meaning of that provision, on its own it cannot justify a referral to the Enlarged Board. A referral is justified only if at least two Board of Appeal decisions come into conflict with the principle of legal uniformity. The object and purpose of Article 112(1)(b) EPC is to have an Enlarged Board decision re-establish legal uniformity when it has clearly been disrupted, not to intervene in legal devel- opment. This is discussed in more detail in the following.
7.3.2 The EPC as it stands assigns inter- pretation of the EPC with its numerous undefined legal terms ultimately to the Boards of Appeal (see point 7.2.5 above). They are responsible for defining how the law is to be applied and where appropriate adapted to developments in patent law. To a greater or lesser extent the issue in every case is whether or not the situation is covered by an abstractly formulated regulation. Thus over time case law has given e.g. the notions of invention, novelty, inventive step and industrial applicability increasingly precise meanings with which the Office and other patent system stakeholders can align themselves in their daily prac- tice. Hence in view of the direction that patent law has taken by means of the Boards' case law, appeals against deci- sions of the Examining and Opposition Divisions mostly operate within legally secure bounds.
7.3.3 Particularly in the field of new technologies, the Technical Boards often have to subject their established case law to critical review, applying accepted judicial procedure and general legal principles to decide whether the often broadly formulated undefined legal terms in the EPC are applicable to the specific nature of the new field, i.e. in particular whether the existing widely accepted case law also yields acceptable solutions in the new field. It is entirely conceivable that the interpretation of undefined legal terms in the light of the EPC's purpose and principles will necessitate drawing further distinctions which, depending on what they include or exclude, may determine whether a patent is granted or refused in a specific case.
amendments will be necessary in the course of time if legal solutions that the Boards initially deem correct prove to be mistaken in new situations and cease to be convincing jurisprudence. Such changes of direction in legal development are a normal part of judicial activity, and there is no need to speak of different decisions within the meaning of Article 112(1)(b) EPC simply because departures from earlier practice are deemed necessary when homing in on the right solution to a specific case (see however Moufang in: Schulte, Patentgesetz mit EP, 8th edition 2008, Article 112 EPC (annex to paragraph 73) marginal number 42).
7.3.5 Thus even a radical shift in juris- prudence need not necessarily be construed as a different decision within the meaning of Article 112(1)(b) EPC vis--vis earlier case law, provided that the Board corrects itself and mostly in explicit fashion declares its earlier practice to be no longer relevant. The President does not acquire the right of referral simply because he prefers the earlier decision (Joos in: Singer/Stauder, Europisches Patentbereinkommen, 5th edition 2010, Article 112, marginal number 25; see however Moufang in: Schulte, Patentgesetz mit EP, 8th edition 2008, Article 112 EPC (annex to paragraph 73) marginal number 42). Such corrections are a normal part of the application and development of the law and do not constitute a difference that could be corrected by means of a presi- dential referral to the Enlarged Board, overriding the interpretative power of the Boards. In fact, shifts of this kind when identified as such leave the Office as patent granting authority in no doubt how the EPC is to be interpreted according to the Boards' latest findings. This may entail altering the Examination Guide- lines, but not having the case law reviewed by the Enlarged Board. It is another matter if the Boards themselves see a need to refer points of law to the Enlarged Board in the light of a change in their practice.
7.3.6 The same should apply where the Boards' case law has developed over an extended period and in the course of several decisions has gradually arrived at solutions which clearly and justifiably move away from the initial premise, even if the public and the patent granting authority have found earlier solutions acceptable. In that way, too, legal devel- opment has followed a course which, while not entirely linear, as long as it is transparent does not justify speaking of different decisions that could be grounds for a referral.
7.3.7 Legal rulings are characterised not by their verdicts, but by their grounds. That is the only way of assessing the courts' opinion, and the ability to assess that is in turn the key to legal certainty. The Enlarged Board has already taken this line in its decision G 3/93 (OJ EPO 1995, 18, Reasons, point 2), where it took obiter dicta into account in exam- ining a divergence (likewise Moufang in: Schulte, Patentgesetz mit EP, Article 112 EPC (annex to paragraph 73) marginal number 45).
7.3.8 The conclusion that must be drawn is that the Enlarged Board cannot develop the law in the same way as the Boards of Appeal, because it does not have to decide on facts of pending appeals, but only in specific instances and only in the aforementioned context of points of law referred to it under Article 112(1) EPC. This applies a fortiori to referrals by the President, which do not even arise from a specific appeal.
influence the assessment of individual issues is by breaking with previous practice and pointing in a new direction or by confirming the approach adopted by a Board.
In the process however the Enlarged Board must also consider whether the divergent decisions might not be part of a constant development, possibly still ongoing, in jurisprudence on recent patent law issues, in the course of which older decisions have lost their signifi- cance and so can no longer be consid- ered in connection with newer decisions. Such putative differences do not justify presidential referrals, legal development being one of the principal duties of the Boards of Appeal, in particular in new territory.
Hence the President has no right of referral under Article 112(1)(b) EPC simply in order to intervene, on whatever grounds, in mere legal development if on an interpretation of the notion of "different decisions" in the sense of conflicting decisions there is no need for correction to establish legal certainty.
The questions of the referral 8. In the light of these fundamental considerations on the interpretation of Article 112(1)(b) EPC, the questions that have been referred will now be considered.
include "any programmable apparatus", including e.g. a mobile phone. It is further clarified that "the methods referred to in hypothetical examples are intended to be methods which can be implemented wholly by computer."
While these definitions may be helpful for the Enlarged Board in interpreting the referral, it should be made clear that the Board cannot be bound by them when it interprets the case law. The meaning of these terms in patents and appeal cases must rather be determined by an analysis of how the skilled addressee would have understood them in the context in which they were used.
It should be pointed out that if "com- puters" include mobile phones, and the hypothetical methods are meant to be those which can be implemented wholly by computer, they would include for example methods of generating radio carrier waves using particular analogue circuits. This was probably not intended to be included in the definition of a "computer implemented method" by the referral.
9.2 The term "technical" We do not attempt to define the term "technical". Apart from using this term in citing the case law, in what follows the Enlarged Board only makes the asser- tions that "a computer-readable data storage medium" and a cup have tech- nical character and that designing a bicycle involves technical considerations, in order to be able to explore the conse- quences of that case law. It is to be hoped that readers will accept these assertions without requiring a definition of exactly what falls within the bound- aries of "technical". This question is discussed in some more detail for the particular case of programs for computers in the section relating to Question 4 (see point 13 below).
"Can a computer program only be excluded as a computer program as such if it is explicitly claimed as a computer program?"
However the substance of these claims, i.e. the underlying method to be performed by a computer, is often identical," (referral, page 4).
The discussion also refers to "the func- tion of the computer program (does the claimed program have technical char- acter) rather than the manner in which it is claimed (e.g. as a computer program, a computer program product or a com- puter-implemented method)," (referral, page 5).
computer programs computer program products, storing a computer program.
If a particular claim to a computer program ("1. A program for a computer comprising instructions to carry out steps x, y, z,") is excluded from patent- ability by Article 52(2) EPC, are any of the following (or anything else) automati- cally excluded under the same article?
"2. A computer system loaded with the program of claim 1."
"3. A method of operating a computer comprising executing the program of claim 1." "4. A computer program product storing the program of claim 1."
10.2 The only "divergence" in the case law identified by the referral with respect to this question is between the decisions in cases T 1173/97, IBM (OJ EPO 1999, 609) and T 424/03, Microsoft, dated 23 February 2006. It is argued in the referral (see pages 5 and 6) that according to T 424/03 only a claim of the form "computer program for method x" could possibly be excluded from patent- ability as a computer program as such, whereas claims of the form "computer- implemented method x" or "computer program product storing executable code for method x" would not be excluded (irrespective of the nature of the method x). T 1173/97 is said however to place the emphasis on the function of the computer program rather than on the manner in which it is claimed, for example as a computer program product or a computer-implemented method.
"A computer program product directly loadable into the internal memory of a digital computer, comprising software code portions for performing the steps of [independent method] claim 1 when said product is run on a computer,"
"A computer program product stored on a computer usable medium, comprising: computer readable program means for causing a computer to [carry out the various steps of method claim 1]."
"In the view of the Board, a computer program claimed by itself is not excluded from patentability if the program, when running on a computer or loaded into a computer, brings about, or is capable of bringing about, a technical effect which goes beyond the 'normal' physical inter- actions between the program (software) and the computer (hardware) on which it is run.
'Running on a computer' means that the system comprising the computer program plus the computer carries out a method (or process) which may be of the kind according to claim 1. 'Loaded into a computer' means that the com- puter programmed in this way is capable of or adapted to carrying out a method which may be of the kind according to claim 1 and thus constitutes a system (or device or apparatus) which may be of the kind according to claim 14."
"Furthermore, the Board is of the opinion that with regard to the exclusions under Article 52(2) and (3) EPC, it does not make any difference whether a computer program is claimed by itself or as a record on a carrier ... ."
10.2.3 Since the Board had come to the conclusion that some programs, claimed alone, are excluded from patentability, it must follow from this statement that such a program claimed "as a record on a carrier", i.e. on a computer-readable medium, would also be excluded. The reasoning supporting this conclusion can be seen in the following quotations.
for instance, electrical currents) deriving from the execution of the instructions given by programs for computers cannot per se constitute the technical character required for avoiding the exclusion of those programs." Reasons, point 6.3: "Although such modifications may be considered to be technical, they ... cannot be used to distinguish programs for computers with a technical character from programs for computers as such." The same evidently applies to the physical modifications of a medium (e.g. the pits created in a CD-ROM) caused by storing a program, and this would appear to be what the Board meant by Reasons, point 9.3: "[T]he hardware is not part of the invention. ... Furthermore, it is clear that if, for instance, the computer program product comprises a computer-readable medium on which the program is stored, this medium only constitutes the physical support on which the program is saved, and thus constitutes hardware."
10.2.4 Considering that according to Article 52(1) EPC (in both 1973 and 2000 versions) "European patents shall be granted for any inventions" provided they are new, inventive and industrially applicable, the reasoning in 9.3 that, (i) when a computer program product comprises a computer-readable medium, the medium constitutes hardware, and (ii) hardware is not part of the invention, makes it clear that the Board considered that a claim to a computer program product could not escape the exclusions of Article 52(2) EPC merely by comprising a computer-readable medium. Reasons, points 6.2 and 6.3 cited above at least suggest that the Board also considered that claiming a computer loaded with a program or the execution of a program on a computer would not be sufficient to escape the exclusion.
10.4 It is notable that the definition of further technical effect in Reasons, point 13 makes no reference to the state of the art. Thus according to this decision it may be determined whether a claim to a computer program is excluded from patentability by Article 52(2) and (3) EPC independent of the prior art. That is, the identified further technical effect need not be new. By taking this position the Board consciously abandoned the so- called "contribution approach" which had been applied, somewhat inconsistently, in the earlier case law. This was clearly a deliberate development of the case law (the inconsistency of the previous case law having previously been identified in an article, "Patentability of computer- software-related inventions", by the then chairman, P. van den Berg, in "The law and practice of the Enlarged Board of Appeal of the European Patent Office during its first ten years", issued by the members of the Enlarged Board of Appeal, 1996, pages 29 to 47). To our knowledge no decision of the Boards of Appeal has since challenged this choice by the Board in T 1173/97. It therefore stands as the established case law, and cannot be overturned by this Opinion, for the reasons given above (see point 7).
10.5 T 1173/97 also drew the conse- quence from its abandonment of the "contribution approach" that "Deter- mining the technical contribution an invention achieves with respect to the prior art is therefore more appropriate for the purpose of examining novelty and inventive step than for deciding on possible exclusion under Article 52(2) and (3)," (Reasons, point 8, second paragraph).
10.6 For readers unfamiliar with the jargon, an analogy may help to under- stand the distinction between the "contri- bution approach" and the approach adopted by the Board in T 1173/97. Note, however, that what follows is intended to be merely illustrative, not definitive.
Suppose a patent application claims a cup carrying a certain picture (e.g. a company logo). We assume that no effect beyond information, "brand aware- ness" or aesthetic pleasure is ascribed to the picture. According to the "contribu- tion approach", cups are known, so that the "contribution to the art" is only in a field excluded from patentability by Article 52(2) EPC and the application may be refused under this provision, i.e. the European patent application is considered to relate to (cf. Article 52(3) EPC) an aesthetic creation, a presenta- tion of information or possibly even a method for doing business "as such".
Article 52(2) EPC. Whether or not the claim also includes the feature that the cup has a certain picture on it is irrele- vant. This approach, at least as formu- lated in e.g. T 258/03, Hitachi (OJ EPO 2004, 575) and T 424/03, has been characterised in some of the amicus curiae briefs as the "any hardware" or "any technical means" approach.
unequivocal and stands alone as a reason for the claim not to be excluded under Article 52(2) EPC.
10.7.1 The decision in T 424/03 did go on to note (also in Reasons, point 5.3) that the particular program involved had the potential of achieving a further technical effect when run and thus also contributed to the technical character of the claimed subject-matter. This fact however was not necessary to the conclusion that the claimed subject- matter avoided exclusion, since according to the reasoning of T 258/03 any technical means claimed was sufficient to overcome the exclusion of Article 52(2) EPC. The question whether the program itself caused a "further technical effect" when run, and would therefore also qualify as technical means, only assumed importance for the question of inventive step in parallel to these decisions the Board had been developing an approach to the appraisal of inventive step taking into account the fact that some of the features of a claim might, considered alone, fall under the exclusions of Article 52(2) EPC (see T 154/04, Duns, OJ EPO 2008, 46, for an exposition of the approach). For this approach it is important which features contribute to the technical character of the claimed subject-matter, since only such features are taken into account for the assess- ment of inventive step. In the particular case of T 424/03, both the computer- readable medium and the program itself were features which gave the subject- matter of the particular claim as a whole a technical character, and were both therefore to be taken into account for the assessment of its inventive step.
10.7.2 Thus finally the Board had arrived at a conclusion which clearly contra- dicted the position (or rather one of the positions) taken in T 1173/97. T 1173/97 declared "Furthermore, the Board is of the opinion that with regard to the exclu- sions under Article 52(2) and (3) EPC, it does not make any difference whether a computer program is claimed by itself or as a record on a carrier ... ," (Reasons, point 13), whereas T 424/03 stated "The subject-matter of claim 5 has technical character since it relates to a computer- readable medium, i.e. a technical product involving a carrier (see decision T 258/03 Auction method/Hitachi ...)", (Reasons, point 5.3).
10.8 Thus there was a difference between the positions taken in T 1173/97 and T 424/03 on this point. It is still however necessary to decide whether this difference constitutes a divergence allowing a question to be referred by the President on the point. The considera- tions to be taken into account have been discussed in points 5 to 7 above.
10.8.1 Although both these cases were decided by Board 3.5.01 as an organ- isational unit, the compositions of the Board were completely different, so that a referral on the basis of these two decisions is not excluded (see point 6 above). However there are factors which suggest that the difference should be treated as a development of the case law as discussed in point 7.3 above.
Firstly and most importantly the referral does not identify, and we are not aware of, any decision whatsoever of one of the Boards of Appeal of the EPO which follows T 1173/97 on this point (although T 1173/97 is evidently considered seminal in its definition of "further technical effect" and abandonment of the contribution approach to exclusion).
10.8.2 Secondly, the conclusion arrived at in T 424/03 has not been challenged in any later decisions; nor was it isolated but rather came as the last of a series of decisions, the logic of which is consistent and, at least to our knowledge, has also not been challenged in any later decision of a Board of Appeal of the EPO (national court decisions are another matter, but cannot be taken into account for admissibility as discussed above at point 5). For the reader's convenience we rehearse this logic, as we understand it, in what follows.
10.8.3 As discussed above the Board in T 1173/97 consciously abandoned the "contribution approach" and also expressed the opinion (at Reasons, point 13) that "with regard to the exclu- sions under Article 52(2) and (3) EPC, it does not make any difference whether a computer program is claimed by itself or as a record on a carrier ... ." These two positions are, however, contradictory when considered in the context of the case law of the Boards of Appeal as a whole.
EPC from patentability is, according to T 1173/97, always to be decided without regard to the prior art.
10.8.5 Following this principle, a claim to a particular kind of computer-readable medium memory with certain special properties, e.g. a Blu-Ray disk, is evidently not excluded from patentability by Article 52(2) and (3) EPC, whether or not it is new at the relevant date. But applying the principle consistently, the claim does not have to be a special kind of memory "A computer-readable data storage medium," specifying no further details, has the "technical effects" of being computer-readable and of being capable of storing data. And since there is no entry in the list of Article 52(2) EPC relating to computer-readable media as such there is no requirement for a "further" effect going beyond the basic properties of such a computer-readable storage medium. In short, according to the logic of T 1173/97 the following claim is not excluded from patentability by Article 52(2) and (3) EPC: "A computer-readable storage medium."
Aktuell?, Mitteilungen der deutschen Patentanwlte 2003, 537). Thus according to Board of Appeal case law, since the claim "A computer-readable storage medium" is not excluded from patentability by Article 52(2) and (3) EPC, neither is a claim "A computer- readable storage medium storing com- puter program X" (cf. "A cup decorated with picture X").
10.8.7 It might be argued that whereas "A Blu-Ray disk with program X written on it" would escape the exclusion of Article 52(2) EPC, "A computer-readable storage medium with program X written on it" should not. The only basis for such an argument which the Enlarged Board can envisage would be that the feature "computer-readable storage medium" loses its technical nature because it is too generic or "functionally defined". There is however no case law known to the Enlarged Board that would support this view.
approach in the general case law of the Boards of Appeal.
The arguments above apply with equal force to claims which "mention" a computer (as the referral puts it in Question 2).
10.9 Returning to the direct question of admissibility of the referred question it is further noted that there was a period of approximately seven years between the issuance of the two decisions, a period which, although not very long in legal terms, is nonetheless compatible with the notion of development of the case law.
10.10 It is perhaps regrettable that the Board in T 424/03 did not mention the fact that it was deviating from an earlier decision, as foreseen in the Rules of Procedure of the Boards of Appeal, Article 20(1) (previously Article 15(1)). However in the judgement of the Enlarged Board this fact alone is not sufficient to disqualify the process as a legitimate development of the case law.
10.11 While the final outcome of the cases is not the decisive factor in deter- mining the admissibility of a referral (see point 7.3.7 above), the Enlarged Board also notes that there is no suggestion in the referral that the change of approach from Article 52(2) EPC to Article 56 EPC had any effect on the final result of T 424/03.
10.12 Thus in the judgement of the Enlarged Board, although T 424/03 does deviate from a view expressed in T 1173/97 this is a legitimate develop- ment of the case law and since T 1173/97 has not been followed by any Board on this particular point there is no divergence which would make the referral of this point to the Enlarged Board of Appeal by the President admissible. Question 1 is therefore not admissible.
10.13 The present position of the case law is thus that (phrasing the conclusion to match Question 2 of the referral) a claim in the area of computer programs can avoid exclusion under Article 52(2)(c) and (3) EPC merely by explicitly mentioning the use of a computer or a computer-readable storage medium. But no exposition of this position would be complete without the remark that it is also quite clear from the case law of the Boards of Appeal since T 1173/97 that if a claim to program X falls under the exclusion of Article 52(2) and (3) EPC, a claim which specifies no more than "Program X on a computer-readable storage medium" or "A method of operating a computer according to program X" will always still fail to be patentable for lack of an inven- tive step under Articles 52(1) and 56 EPC. Merely the EPC article applied is different. While the Enlarged Board is aware that this rejection for lack of an inventive step rather than exclusion under Article 52(2) EPC is in some way distasteful to many people, it is the approach which has been consistently developed since T 1173/97 and since no divergences from that development have been identified in the referral we consider it not to be the function of the Enlarged Board in this Opinion to overturn it, for the reasons given above (see point 7.3.8).
under Article 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 assess- ment 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.
10.13.2 We note, in passing, that it is somewhat surprising that the referral does not address any of its questions to the validity of this way of judging an inventive step, an issue which is surely of general interest (and one which Lord Justice Jacob proposed should be put to the Enlarged Board "How should those elements of a claim that relate to excluded subject-matter be treated when assessing whether an invention is novel and inventive under Articles 54 and 56?", Aerotel/Macrossan at 76, ques- tion (2)). The Board can only speculate that the President could not identify any divergence in the case law on this issue, despite the fact that (at present) approximately seventy decisions issued by a total of fifteen different Boards (in the sense of organisational units) cite T 641/00, COMVIK (OJ EPO 2003, 352), and over forty decisions by eight Boards cite T 258/03, Hitachi, the decisions which essentially defined the approach. Nor is the Enlarged Board aware of any divergence in this case law, suggesting that the Boards are in general quite comfortable with it. 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.
"(a) Can a claim in the area of computer programs avoid exclusion under Art. 52(2)(c) and (3) merely by explicitly mentioning the use of a computer or a computer-readable storage medium?
(b) If Question 2(a) is answered in the negative, is a further technical effect necessary to avoid exclusion, said effect going beyond those effects inherent in the use of a computer or data storage medium to respectively execute or store a computer program?"
Admissibility 11.1 Firstly the question has to be inter- preted again, although its intention is in this case fairly clear. While the question says "merely by explicitly mentioning", it may be presumed that the referral does intend there to be a functional relation- ship, such as "Method of operating a computer according to program X".
computers must show a "further tech- nical effect" in order to escape exclusion from patentability under Article 52(2) EPC.
"Method claims are, in essence, a series of instructions or steps which are to be carried out by any capable entity (this could be a person, a machine, a combi- nation thereof or indeed a computer). A computer-implemented method corre- sponds to the specific case of the entity for carrying out the steps being a computer. In the same way a computer program is a series of instructions or steps, constituting a method, whereby the instructions or steps are carried out by a computer. Thus claims for a computer program and a computer- implemented method can be seen as having an identical scope" (referral, page 8).
It is to be noted that this argumentation is based on the features claimed actually being the same, rather than any consid- erations of the protection conferred, in the sense of e.g. Article 123(3) EPC.
comprising placing a shoe in a position touching a surface rotatable in a direc- tion ..." clearly requires the presence and involvement of the shoe polishing machine.
Tigers eat meat. Meat is a word. There- fore tigers eat words.
Clearly there must be an error in this argument. It occurs because "meat" is being used differently in the two premises. In the second premise what is being discussed is not the substance meat, but the name of the substance. These are two different things, and the usual way of distinguishing them is to put the name in quotation marks. For a famous but more complicated example of this kind of wordplay see Lewis Carroll's "Through the Looking Glass (and What Alice Found There)", search expression "The name of the song is called". In such a complicated situation it is easy to confuse names or descriptions and the things they refer to.
computer may involve the increment step being carried out many times. It is moreover possible to talk of a computer loaded with a set of instructions or of a computer-readable medium storing a set of instructions. The concepts of a computer (or any other machine) "loaded" with a method, or a computer- readable medium "storing" a method, appear to be meaningless. The only way a meaning can be assigned to these concepts is to assume that they are elisions of, respectively, a computer loaded with and a computer-readable medium storing instructions to carry out a method.
11.2.6 The referral's confusion on this point seems to arise from its equating a method claim, which is a description (or at least delimitation) of a method, with the method it delimits: "Method claims are, in essence, a series of instructions or steps ... In the same way a computer program is a series of instructions or steps, constituting a method, whereby the instructions or steps are carried out by a computer. Thus claims for a computer program and a computer implemented method can be seen as having an identical scope."
11.2.7 While on a correct interpretation there is a distinction between a computer program and the corresponding computer-implemented method, it is conceivable that there is nonetheless a divergence in the case law of the Boards of Appeal, resulting from a false usage by Boards of the word "program". The referral asserts that two decisions take the same view as it does that a claim to a computer program has the same scope as a claim to a computer imple- mented method (or that the method encompasses the program), namely T 1173/97 at Reasons, point 9.6, second paragraph, lines 1 to 3, and T 38/86, IBM (OJ EPO 1990, 384), Reasons, point 14 (referral, page 8). Even though the argument made in the referral that a program is the same as a method is not convincing, it is nonetheless necessary to consider whether Boards have in fact used the expression "computer program" to mean a method in the cases where such use is asserted in the referral.
11.2.8 The first citation (i.e. T 1173/97 at Reasons, point 9.6, second paragraph, lines 1 to 3) is "It is self-evident that a claim to such a computer program product must comprise all the features which assure the patentability of the method it is intended to carry out when being run on a computer." There is however no problem in interpreting this as being a reference to the instructions which make up the program. It does not imply that the Board in T 1173/97 neces- sarily saw the features of a claim to a computer program product as being method steps. Indeed the sentence which immediately follows the cited one gives the opposite impression: "When this computer program product is loaded into a computer, the programmed computer constitutes an apparatus which in turn is able to carry out the said method." This would appear to indicate that the Board in that case saw computer programs in the same way as the Enlarged Board does.
11.2.9 The second citation (i.e. T 38/86, IBM, Reasons, point 14) is "Although a computer program is not expressly recited in Claim 1, it is clear to a reader skilled in the art that the claim covers the case in which a computer program is used and, indeed, in the only embodi- ment disclosed in the application the text processing system is controlled by a set of programs and data stored in memory." Claim 1 was a method claim. However this does not mean that a computer program is a method, merely that, as it says, the claim could be satisfied by the use of a computer program. The shoe polishing method mentioned above may be satisfied by a particular use of the shoe polishing machine, but this does not mean that claims to the machine and to the method have the same scope or that the scope of the method encom- passes the scope of the machine. If anything the scope of (in the sense of protection conferred by) a claim to the machine encompasses the scope of a claim to a method of using the machine see G 2/88 (OJ EPO 1990, 93, Headnotes I and II).
11.3 Thus no divergence in the case law supporting this question has been identi- fied by the referral and the question is therefore not admissible.
"(a) Must a claimed feature cause a technical effect on a physical entity in the real world in order to contribute to the technical character of the claim?
(b) If Question 3(a) is answered in the positive, is it sufficient that the physical entity be an unspecified computer?
(c) If Question 3(a) is answered in the negative, can features contribute to the technical character of the claim if the only effects to which they contribute are independent of any particular hardware that may be used?"
Admissibility 12.1 The referral argues that a diver- gence arises as follows: "According to decisions T 163/85 [BBC, OJ EPO 1990, 379] and T 190/94 [Mitsubishi, dated 26 October 1995], a technical effect on a physical entity in the real world was required. This was however not the case in T 125/01 [Henze, dated 11 December 2002] and T 424/03. In these decisions the technical effects were essentially confined to the respective computer programs," (referral, page 10).
12.2 There are two evident problems with this assertion. The first is that the referred question relates to individual features, rather than the claimed subject- matter as a whole. The referral does not specify, and the Enlarged Board cannot identify, any passage in the cited decisions relating to the individual features. Indeed the referral does not even mention the fact that the question relates to individual features in its discussion of the alleged divergence.
the question of which claimed features contribute to that technical character and therefore should be taken into account for the assessment of whether there is an inventive step.
12.2.2 It is in fact a well-established prin- ciple that features which would, taken in isolation, belong to the matters excluded from patentability by Article 52(2) EPC may nonetheless contribute to the tech- nical character of a claimed invention, and therefore cannot be discarded in the consideration of the inventive step. This principle was already laid down, albeit in the context of the so-called "contribution approach", in one of the earliest deci- sions of the Boards of Appeal to deal with Article 52(2) EPC, namely T 208/84, VICOM (Reasons, point 4 ff.).
12.3 The second problem with the alleged divergence is that the decisions T 163/85 and T 190/94, said in the referral to require a technical effect on a physical entity in the real world, simply did not do so. They merely accepted this as something sufficient for avoiding exclusion from patentability; they did not state that it was necessary. The referral does not identify any passages requiring such an effect and the Enlarged Board cannot find any.
12.4 Thus there is no divergence. The other two decisions cited considered that there were technical effects; whether the Boards concerned considered that these technical effects were on a physical entity in the real world is irrelevant.
12.5 This question is therefore also inadmissible.
"(a) Does the activity of programming a computer necessarily involve technical considerations?
(b) If Question 4(a) is answered in the positive, do all features resulting from programming thus contribute to the technical character of a claim?
(c) If Question 4(a) is answered in the negative, can features resulting from programming contribute to the technical character of a claim only when they contribute to a further technical effect when the program is executed?"
Admissibility 13.1 Again the question needs some interpretation. The Enlarged Board supposes that "the activity of program- ming a computer" is intended to relate to the intellectual activity of working out what are the steps to be included in a computer program rather than the simple physical activity of entering a program into some computer.
13.2 The referral asserts (on pages 11 and 12), correctly in our view, that T 1177/97, SYSTRAN, dated 9 July 2002, considers that programming always involves technical considerations, at least implicitly, and that T 172/03, Ricoh, dated 27 November 2003, assumes the same in that it considers the skilled person, who, it is emphasised, is a technical expert, to be a software project team, consisting of programmers. On the other hand, T 833/91, IBM, dated 16 April 1993, T 204/93, AT&T, dated 29 October 1993, and T 769/92, Sohei, OJ EPO 1995, 525, are said to consider the programmer's activity, programming, to be a mental act, falling within the exclusions of Article 52(2) EPC.
13.3 However, there is no contradiction between these positions, as may be seen by considering the same case in a non-controversial field, for example bicycle design. Designing a bicycle clearly involves technical considerations (it may also involve non-technical, e.g. aesthetic, considerations) but it is a process which at least initially can take place in the designer's mind, i.e. it can be a mental act and to the extent that it is a mental act would be excluded from patentability, just as in the cited cases T 833/91, T 204/93 and T 769/92 (cf. also T 914/02, General Electric, dated 12 July 2005, Reasons, point 2.3 and T 471/05, Philips, dated 06 February 2007, Reasons, points 2.1 and 2.2).
13.4 Hence the question does not satisfy the requirement for a divergence in the case law and is therefore inadmissible.
13.5 While the referral has not actually identified a divergence in the case law, there is at least the potential for confu- sion, arising from the assumption that any technical considerations are suffi- cient to confer technical character on claimed subject-matter, a position which was apparently adopted in some cases (e.g. T 769/92, Sohei, Headnote I). However T 1173/97, IBM sets 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.
considered to have a technical character. In the same way, it would appear that the fact that fundamentally the formulation of every computer program requires tech- nical considerations in the sense that the programmer has to construct a proce- dure that a machine can carry out, is not enough to guarantee that the program has a technical character (or that it constitutes "technical means" as that expression is used in e.g. T 258/03, Hitachi). By analogy one would say that this is only guaranteed if writing the program requires "further technical considerations".
The referral of 22 October 2008 of points of law to the Enlarged Board of Appeal by the President of the EPO is inadmissible under Article 112(1)(b) EPC.
