La conferència de revisió de l'CPE de 11/2000 proposava insertar "en tots els camps de la teconològia" al paragraf 1 i esborrar el paragraf 4.

Article 52: Invencions patentables
- Les patents europees hauràn de ser concedides als invents [ en tots els camps de la tecnològia ], sempre i quan aquests siguin nous, representin un avenç o sig+uin susceptibles de la seva aplicació industrial.
- Els següent particulars no poden ser reconeguts com a invencions dins dels significat del paragraf 1:
- descobriments, teories cièntifiques i metodes matemàtics;
- creacions estètiques;
- esquemes, normes i mètodes per portar a terme actes mentals, jugar a jocs o fer negocis, i programes per ordinadors;
- presentacions d'informació.
- Les directrius del paragraf 2 han d'excloure la patentibilitat dels temes substancials o activitats referides en aquestes directrius només en tant que una sol·licitud de patent europea o patent europea tingui relació amb aquests temes o activitats com a tals.
- Els metodes per al tractament del cos humà o animal, per a cirugia, terapia i els metodes diagnòstics practicats al cos humà o animal no podràn esser considerats com a invencions que siguin susceptibles de la seva aplicació en la industria en el sentit del paragraf 1. Aquesta directriu no pot èsser aplicada a productes, en particular substàncies o compostos, fets per utilitzar-se en els metodes anteriorment esmentats.
Until the late 80s, this was unanimously interpreted as clearly excluding software patents, as they are usually understood in the discussion today. E.g. in 1990 the Technical Board of Appeal of the EPO
explains its refusal of 1984 to allow a document processing system on the basis of Art 52.2c:

The reason given for the refusal was that the contribution to the art resided solely in a computer program as such within the meaning of Article 52 EPC, paragraphs 2(c) and Consequently, this subject-matter was not a patentable invention within the meaning of Article 52(1) EPC, in whatever form it was claimed.
In arriving at this conclusion the Examining Division argued on the basis that Claims 1 and 2 related to a method for automatically abstracting and storing an input document in an information storage and retrieval system and Claims 3-6 to a corresponding method for retrieving a document from the system. The claims specifically referred to a dictionary memory, input means, a main memory and a processor. These hardware elements were classical elements of an information and retrieval system (...) and objectionable under Article 54(2) EPC as lacking novelty. According to the present description (...) the method steps were implemented by programming such a classical system. The claimed combination of steps did not imply an unusual use of the individual hardware elements involved. The claims merely defined a collocation of known hardware and new software concerned with document information to be stored but not with an unexpected or unconventional way of operating the known hardware. The differences between the prior art and the subject-matter of the present application were defined by functions to be realised by a computer program which was used to implement a particular algorithm, or mathematical method, for analysing a document. In other words the steps of the method defined operations which were based on the content of the information and were independent of the particular hardware used.
In other words, a collocation of standard computing hardware with new computing rules (algorithms), in whatever form it is presented in the claim, would be excluded from patentability.
This was also clearly expressed in the Examination Guidelines of the European Patent Office of 1978.
However, in 1985 the Guidelines were revised and in particular the limits of patentability with respect to programs for computers were blurred. In two decisions of 1986, the EPO's Technical Board of Appeal reinterpreted the list of exclusions to mean that only "non-technical" innovations should be excluded, but refused to define "technical" -- a concept that was not mentioned in the law. From thereon the EPO embarked on a slippery slope by gradually widening the meaning of what could be understood to be "technical".
The EPO's reinterpretation of 1985/1986 and the subsequent loosening were criticised by law scholars such as Krasser, Benkard i Vivant and have led to a schism of judicial practise, which a new EU directive is supposed to overcome.

The decisions at the EPO were understood to have been taken "in response to pressure from the computer industry and trends emerging in the US".

Bernhardt & Kraßer 1986: Lehrbuch des Patentrechts
- German manual of patent law of 1986, explains the correct interpretation of Art 52 EPC, as used by the German courts, and explains that the German courts are thereby resisting "pressure from the software industry". Krasser also mentions the revision of the EPO's examination guidelines in 1985 and explains that they, while still unclear, seem to be moving into the direction demanded by "the industry".
A la
conferència diplomatica que va tenir lloc el novembre de l'any 2000, la OEP va intentar esborrar tot rastre de les definicions restrictives en termes com ara
invenció,
tecnicitat,
aplicabilitat industrial, etc de la llei i en el seu lloc obrir el camí per a la patentatibilitat de totes les
solucions pràctiques i repetibles de problemes. Això ha permés a la OEP de formular una proposta molt curta:

Invencions patentables
Les patents europees hauràn de ser concedides als invents [ en tots els camps de la tecnològia ], sempre i quan aquests siguin nous, representin un avenç o sig+uin susceptibles de la seva aplicació industrial.
As a result of an uproar of public opinion, politicians from major countries prevented this planned change of Art 52. Yet the "Base Proposal" version was accepted as a new wording for Art 52(1), and Art 52(4) was deleted (whereby the concept of "industrial application" was further weakened).
Thus the revised version of Art 52 EPC, which is not yet in force, contains the TRIPs formula "in all fields of technology", but fails to define the new term "technology", which doesn't exist in the old EPC. Thus clause (2) seems relativised by an indeterminate concept from an international treaty. It would have been in the interest of clarity and legal security to concretise this concept, e.g. by explaining clearly what is to be understood by a "technical invention" and why algorithms, business methods and rules for operating known data processing equipment do not belong into this category. Instead the legislators opted for introducing indeterminate concepts and potential contradictions into the law, which are then likely to be resolved by putting the appositive "as such" from 52(3) in quotes to make it appear mysterious and unclear, so as to allow the patent judiciary to rely on its own favored interpretation of "fields of technology" or even to point to alleged WTO constraints, thus giving up the clarity and integrity of national law in favor of arbitrary decisionmaking by the international patent lawyer community.
Art 52(4) about surgery on the human body was "only" reworded and moved to Art 53. This however implies that surgery methods are no longer considered to be non-inventions, non-technical or non-industrial. In this way, the Diplomatic Conference further weakened the TRIPs concepts on which it decided to rely for limiting patentability.
La regulació legal actual sobre els límits de la patentatibilitat és clara i inequívoca. Hi ha, no obstant això, tribunals que consideren aquesta norma inadequada i l'han substituït per una regulació diferent en anticipació d'un canvi de la llei.

En réalité, les règles nationales et conventionnelles sont claires: elles posent sans équivoque un principe de non-brevetabilité du logiciel. Le jeu qui se joue aujourd'hui consiste à contourner d'une manière ou d'une autre celles-ci, par exemple en imaginant de considérer, comme on l'a vu, l'ensemble constitué par le matériel et le logiciel comme une machine virtuelle susceptible (demain ...) d'être breveteée. À ce compte-là, on peut parler brevets. Les brevets susceptibles d'être ainsi obtenus, par ce canal ou un autre, n'ont, toutefois, que la valeur qu'on leur prête - mais il ne faut pas écarter l'hypothèse selon laquelle on finirait par une sorte de consensus à ne pas vraiment la discuter. De fait, l'efficacité de ce countournement des règles légales sera largement fonction du fait qu'un tel consensus se dégagera pour accepter --- contre les règles positives --- que ce nouveau jeu se joue ou non. La question ne se situe plus sur le terrain juridique
stricto sensu.
Després d'un intens debat públic resulta que la norma legal actual és l'adequada i que la jurisprudència recent de l'OEP contradiu tan la llei com l'interés públic. Cal cridar els tribunals a corregir la seva pràctica actual i aplicar la llei.
The European Parliament has passed an amended directive which reconfirms the system of Art 52 EPC and makes it more explicit. Frits Bolkestein and some people in the Council do not like this clarification and propose to opt instead for a revision of the EPC or some other kind of inter-governmental agreement. The UK Patent Office has proposed to rewrite Art 52(3) in a way that allows anything deemed "technical" to be patented. On the other hand it would also be possible to concretise Art 52 EPC itself further in the spirit of the amended directive. Putting positive definitions of "technical field", "technology", "industry" etc, as found in the amended directive, into Art 52ff EPC or its national versions could become a way of implementing the directive.
Proposem opcionalment d'esborrar l'apartat 3 de l'article 52 perquè és purament explicatiu i no agrega cap significat a l'article. El seu lloc és al reglament d'examen de sol·licituds de patents. Suprimir-lo de la llei seria una manera convenient de dir als tribunals que tornin a la interpretació correcta de la llei, que era la predominant durant els anys 70/80.
Auslegung von Art. 52 des Europäischen Patentübereinkommens hinsichtlich der Frage, inwieweit Software patentierbar ist
- Dr. Karl Friedrich Lenz, Professor für Deutsches Recht und Europarecht an der Universität Aoyama Gakuin in Tokio untersucht mit den allgemein anerkannten Methoden juristischer Auslegung, welche Bedeutung dem heute geltenden Text des Art 52 EPÜ beizumessen ist und gelangt zu dem Schluss, dass die Technischen Beschwerdekammern des EPA seit einiger Zeit regelmäßig Patente auf Programme für Datenverarbeitungsprogrammen als solche erteilen und eine beunruhigende Bereitschaft zeigen, die eigenen Wertungen an die Stelle der Wertungen des Gesetzgebers zu setzen.
Moses, the Ten Exclusions from Patentability and "stealing with a further ethical effect"
- Computer programs are both unpatentable and patentable in Europe. How did the European Patent Office's Technical Boards of Appeal gradually manage to patent the unpatentable? Where taboos and artificially induced complexity mine the road, satiric comparison is often the fastest way to a thourough understanding.
Stalin & Software Patents
- In this contribution to the European Patent Office (EPO) mailing list, a European patent attorney cites the EPO Examination Guidelines of 1978 as clear documentary evidence for the intention of the legislator to keep computer programs on any storage medium free from any claims to the effect that their distribution, sale or use could infringe on a patent. But the European Patent Office's Technical Board of Appeal (TBA) apparently considered itself to be a kind of modern Stalin, an ultimate sources of wisdom in matters of whatever complexity, standing high above the legislator and the peoples of Europe, and even above the EPO's own institutions for judicial review. In this way the TBA risks to antagonise the public, to create harmful legal insecurity especially for small patent-holders and to severely damage the delicate process of building confidence in international institutions. The TBA should see itself as a conservator rather than an innovator.
Scandinavia: even without the "as such" clause, stealing can have a further legal effect
- Art 52 of the European Patent Convention (EPC) stipulates that programs for computers as well as mental rules, mathematical methods, ways of presenting information etc are not patentable inventions and may therefore not be claimed as such. The wording "as such" from Art 52(3) has however been used to undo all explicit limits on patentability. The European Patent Office (EPO) has in 1997 begun to subdivide computer programs into two groups, "as-such programs" and "not-as-such programs", and has tried to justify this by historical claims about how art 52 EPC came about. This reasoning is at odds with grammar as well as with history. One particularly nice set of evidence comes from Scandinavia: the Danish and Swedish national versions of art 52 EPC do not literally render Art 52(3) but rather incorporate its meaning in the first line of their version of Art 52(2), coming to exactly the same common sense conclusions to which independent grammatical analyses have come and which are also stated in the early EPO examination guidelines: that a "program as such" is "something that constitutes only a program". It confirms that Art 52(3) merely exhorts examiners to look carefully where the novel achievement really lies, e.g. in a programming solution or in a chemical process which may happen to run under program control.

Berichte der Münchener Diplomatischen Konferenz über die Einführung eines Europäischen Patenterteilungsverfahrens
- In autumn 1973 patent experts of the european governments convened in Munich for 1 month in order to create a unified european patent examination system. This conference led to the conclusion of the European Patent Convention (EPC) and to the creation of the European Patent Office (EPO). Art 52 EPC excludes programs for computers, mental rules, mathematical methods etc from patentability. This principle was further elaborated by the EPO's examination guidelines of 1978 and the initial court practise. However starting in 1986 judges at the EPO and some national courts started to extend the scope of patentability and render the exclusions of Art 52 EPC meaningless. In order to justify this, they used a teleologic and historic method of law interpretation which makes frequent reference to what the legislators in 1973 allegedly meant or did not understand. Therefore we have dug out the relevant documents and taken a look at the (relatively short) account about the negotiations concerning Art 52 EPC. This text offers no support for the EPO's method of interpretation. Quite to the contrary.

EPO decision T 22/85 against IBM archival system
- A Technical Board of Appeal of the European Patent Office (EPO) rejects a patent application which is directed to a program for computers. In 1984, the EPO's examiners had rejected the patents based on the original Examination Guidelines of 1978, saying that the claims referred to a "program for computers". The appellant argued on the basis of newer Guidelines and caselaw that his claims are directed to technical effects and not a program as such. The Board of Appeal rejects the appeal by arguing indirectly that the use of general-purpose computer hardware does not confer technicity on an abstract method: "Abstracting a document, storing the abstract, and retrieving it in response to a query falls as such within the category of schemes, rules and methods for performing mental acts and constitutes therefore non-patentable subject-matter under Article 52 EPC" and "The mere setting out of the sequence of steps necessary to perform an activity, excluded as such from patentability under Article 52 EPC, in terms of functions or functional means to be realised with the aid of conventional computer hardware elements does not import any technical considerations and cannot, therefore, lend a technical character to that activity and thereby overcome the exclusion from patentability."
EPO TBA 2002/03 T 49/99: information modelling not technical, computer-implementation not new
- In March 2002, a Technical Board of Appeal at the European Patent Office (EPO) rejects a patent application for a computerised information modelling system on the grounds that the subject matter is not an invention according to Art 52 EPC. The Board argues largely in the original spirit of the EPO and differs significantly from some other recent EPO caselaw. This is an important reason why industrial patent lawyers are pressing for new patentability legislation. Under a CEC/McCarthy directive, EPO decisions such as this one would no longer be possible.

Patent Jurisprudence on a Slippery Slope
- So far computer programs and other rules of organisation and calculation are not patentable inventions according to European law. This doesn't mean that a patentable manufacturing process may not be controlled by software. However the European Patent Office and some national courts have gradually blurred the formerly sharp boundary between material and immaterial innovation, thus risking to break the whole system and plunge it into a quagmire of arbitrariness, legal insecurity and dysfunctionality. This article offers an introduction and an overview of relevant research literature.
M. Vivant: Le Recours a la Propriété Industrielle
- The article on patents analyses the history of French and European patent jurisdiction. It explains, why the European parliaments decided in the 60-70s against patentability of computer programs and how French courts supported this decision by some very clear verdicts even against software innovations related to the control of industrial production processes. It also explains how the European Patent Office since 1986 gradually deviated from these clear rules in 5 steps of logic-twisting. It warns however that the patents gratend by the EPO are of incertain value and could be negated by any national judge.
Dr. Swen Kiesewetter - Köbinger 2000: Über die Patentprüfung von Programmen für Datenverarbeitungsanlagen
- Ein Patentprüfer zeigt die Ungereimtheiten der Prüfung von Software-Anmeldungen auf. In ihrem Bemühen, ein Gesetz umzuinterpretieren, welches unmissverständlich die Patentierung von Datenverarbeitungsprogrammen verbietet, hat die Rechtsprechung im Laufe der Jahre Funktionsansprüche zugelassen, die es dem Anmelder erlauben, ein Programm zu verkleiden. Aber diese Funktionsansprüche stellen eher Probleme als Lösungen dar, und die Lösung zu diesen Problemen besteht in einem (nicht patentierbaren) Datenverarbeitungsprogramm (als solchem). Probleme zu patentieren ist aber noch weniger zulässig und in seinen Auswirkungen noch bedenklicher als Programme zu patentieren.
Patentfähige Datenverarbeitungsprogramme - ein Widerspruch in sich
- Dr. König, patent attorney from Düsseldorf, points out inconsistencies in the software patent caselaw of the EPO and BGH, criticises "circular conclusions" and argues that the EPO has "done violence to art 52 EPC". Through a "grammatical interpretation" of "programs for computers as such" he finds that this can refer only to all kinds of computer programs without exception, as far as they are claimed alone. The EPC of 1973, transcribed into German law in 1978, no longer allows a distinction between technical and untechnical programs. However it ist still possible to patent program-related combination inventions, which then have to be examined for technicity, novelty, non-obviousness and industrial applicability. Courts have often shown more imagination in "helping themselves over the obstacles of art 52". There is an elegant indirect way to effectively grant full patent protection for computer programs as such while avoiding the recent incoherences of the EPO and BGH jurisdiction. As parts of combination inventions, programs for computers may, just as is frequently the case with discoveries and scientific theories, enjoy full "usage protection", if their distribution can be construed as contributory infringement of a combination invention.

CEC & BSA trying to impose unlimited patentability on Sweden
- In a statement submitted to the Swedish Ministry of Justice on behalf of SSLUG, a group of 6100 programmers and users of free software in the area around Copenhagen and Malmö, Erik Josefsson shows how an influential group at the European Commission and the European Patent Office has eroded the standards of patentability and is trying to impose a regime of patentability on all achievements of the human mind that can help to solve some practical problem. This influential group has also, by overstretching the competence of the EPO's Technical Boards of Appeal, illegally overruled the Swedish courts and damaged the Swedish constitutional order. Even in their most recent decisions in the mid-nineties, the Swedish courts did not agree with the EPO's illegal practice, but now the European Commission is set to force this practice on Sweden by means of "european harmonisation". It was the duty of the EPO to abide by a role of "cold harmonisation" in the first place: act as a conservative follower and summarizer of national caselaw rather than as an innovative trendsetter pursuing its own agenda. Josefsson cites ample examples of patents granted by the EPO and rejected by Swedish courts.
