The question whether SPCs should be available for new therapeutic applications of previously approved active ingredients has been a matter of debate ever since the SPC Regulation for Medicinal Products came into force in the European Union more than a quarter-century ago. While a literal reading of the SPC Regulation would clearly seem to exclude any such possibility, as Article 3(d) requires that the marketing authorization relied upon for an SPC must be the “first” marketing authorization for the corresponding product and Article 1(b) defines the term “product” as simply the active ingredient or combination of active ingredients of a medicinal product, the interpretation of these provisions has been put under scrutiny in a number of referrals to the Court of Justice of the EU.

While the CJEU had initially endorsed a restrictive approach in Pharmacia Italia (C-31/03), MIT (C-431/04) and Yissum (C-202/05), it surprisingly made a complete U-turn in the Neurim judgment (C-130/11) rendered in 2012. In this decision, the Court found that, in the case at hand, the grant of an SPC was not precluded by the existence of an earlier marketing authorization for the same active ingredient.

Yet, the precise conditions and the scope of applicability of the Neurim approach have given rise to considerable controversy and divergent approaches in different EU member states. A referral to the CJEU aimed at clarifying these conditions was made by the Paris Court of Appeal in 2018 (as previously reported on this blog) and left practitioners in eager anticipation of the CJEU’s forthcoming judgment. The fact that this judgment has now been rendered by the CJEU as a Grand Chamber of 13 judges testifies to the significance of the issues at stake.

We have clarity at last, as the CJEU has handed down its judgment in Santen (C-673/18) today.

As it turns out, the CJEU has heeded the advice of its Advocate General who called upon the Court to make a clear choice and either bluntly reject the Neurim approach, or else embrace it wholeheartedly and endorse a broad interpretation of the relevant legal provisions (as previously reported on this blog). Alas, the CJEU chose the first option and concluded in its judgment:

Article 3(d) of [the SPC Regulation] must be interpreted as meaning that a marketing authorisation cannot be considered to be the first marketing authorisation, for the purpose of that provision, where it covers a new therapeutic application of an active ingredient, or of a combination of active ingredients, and that active ingredient or combination has already been the subject of a marketing authorisation for a different therapeutic application.

In reaching this conclusion, the Court reasoned that Article 1(b) defines the “product” of an SPC independently from its use or its approved therapeutic application. Therefore, if an active ingredient is used for a new therapeutic application, this does not make it a different “product” where this same active ingredient has already been used for a different therapeutic application before. Interested readers will note that this is essentially the same conclusion that the CJEU already reached in Yissum (C-202/05) – i.e., prior to its Neurim judgment.

In Santen, the CJEU further addressed the relevance of the concept of “the first marketing authorization within the scope of protection of the basic patent” which was previously invoked in Neurim. In this regard, the Court quite correctly observes that the wording of Article 3(d) does not refer to the scope of protection of the basic patent. According to the CJEU, it follows from the aforementioned strict interpretation of the concept of the “product” that Article 3(d) must be understood as relating to the first marketing authorization for any medicinal product incorporating the active ingredient (or combination of active ingredients) under consideration, regardless of the therapeutic application for which it is approved.

This is furthermore held to be in line with the legislator’s intention to establish a simple and predictable system for the grant of SPCs – whereas any other approach that distinguishes between different therapeutic applications, which as a concept are not even defined in the SPC Regulation, would risk leading national patent offices to adopt complex and divergent interpretations.

The scope of the basic patent therefore has no relevance for determining which is the first marketing authorization within the meaning of Article 3(d). Remarkably, the CJEU explicitly noted, in paragraph 53 of the Santen judgment, that this conclusion is “contrary to what the Court held in paragraph 27 of the judgment in Neurim”.

While there is no further discussion of Neurim in the Santen judgment, it appears safe to assume that Neurim has been overturned in its entirety.

With today’s judgment in Santen, the CJEU has certainly succeeded in reducing the infamous complexity of the European SPC system, albeit at the price of significantly curtailing the incentives for pharmaceutical research and development. This adds to the CJEU’s recent and equally restrictive decisions in Abraxis (C-443/17) (discussed here) and Boston Scientific (C-527/17) (discussed here). One might take this opportunity to reflect upon Lord Justice Jacob’s emphatic admonition in his judgment [2011] EWCA Civ 228 that led to the Neurim referral:

In short, if Neurim are wrong, then the [SPC] Regulation will not have achieved its key objects for large areas of pharmaceutical research: it will not be fit for purpose.

Lastly, after the CJEU’s decision in Santen, it would appear that the pending referral in Novartis (C-354/19) has become obsolete, which was meant to address the question of whether the grant of a second SPC for a different therapeutic application is precluded if the second SPC is filed by the same rights holder who has already been granted a first SPC for the same active ingredient. For now, it seems, the long-lasting controversy over the availability of SPCs for second medical uses has finally been put to rest.

  1. I remember being disappointed at the time by the words of such an esteemed judge.

    Essentially the same issue played out before the US Federal Circuit way back in 1989 (Fisons PLC v. Quigg, 876 F.2d 99). As they put it:
    “Fisons urges that it makes little sense, in view of such goals, to restrict patent term extensions so as to encourage
    development only of new chemical entities (NCEs), and not of new uses and doses for such drugs. Per Fisons, developments of new uses and doses for known compounds are as important as NCE developments. It is irrelevant, however, that we might agree with Fisons that, as a matter of policy, Congress might better achieve its goals through a more liberal grant of patent term extension benefits. Matters of policy are for Congress, not the courts, to decide.”

    1. The EPO EBA seems to have no problem with “dynamic interpretation” being used to re-write the law without troubling the law makers.

      1. Dear LightBlue,

        The role of a judge is not to rewrite the law to please the executive, but that is what happened to Art 53(b). By giving a “dynamic” interpretation to its own case law, the EBA rewrote Art 53(b) and this is a disgrace.

        One could agree or not with the first interpretation given to Art 53(b) but it was at least coherent and acceptable. It was a fact which everybody has had to live with it.

        When you read how the EBA made twists and turns to say on the one hand that the original decisions on Broccoli and Tomatoes were right, but on the other it had to be considered in the light in which the AC and the head of the EPO wanted it to be seen, you honestly wonder what went on to justify this attitude of the EBA.

        It is perfect example of the difference between lawyers and scientists. For a scientist the current might flow or not flow. For a lawyer the current might flow or might not flow, it all depends on which side you stand. Fair enough, it is possible to accept it, but not from a court as important as the EBA.

        It is for the legislator to rewrite the law and as far as the EPC is concerned there is something called like a Diplomatic Conference to do so! It might be more difficult and takes longer than a problematic decision of the EBA, but it is the only right way to amend the EPC.

        All people interested in the topic expected a decision of non-admissibility as for G 3/08. The surprise was thus great when the referral was deemed admissible and the decision requested by the AC and the head of the EPO was delivered.

        After this decision the independence of the BA is at stake. In the Corcoran case the EBA showed at the time that it had some spine and did not rubber stamp the decision of the then head of the EPO who had trodden on the separation of powers. The independence of the EBA has now gone!

        It is to be hoped that the German Federal Constitutional Court will take due notice of those two incidents when it deals with the four cases relating to the independence of the BA.

    2. The Federal Circuit certainly has a valid point, and the CJEU could have easily retreated to the same position. But it did not. In Neurim it girded its loins and boldly interpreted the regulation in such a way that it could meet its objectives. All that was needed at that point was a coherent vision. Is it not a shame that instead of sorting out the consequences of Neurim, the CJEU chose to take a leap backwards and undo its own progressive approach? Could anyone imagine that the EPO’s Enlarged Board of Appeal would have scrapped Swiss-type claims 8 years after G 1/83? Not in your wildest dreams… (or at least not before our “dynamic” times of Tomatoes, Broccoli and Pepper?)

  2. This new decision of the CJEU means in other words that a SPC cannot be obtained for a second medical use of a known product when a SPC has already been granted to the product.

    What is remarkable is that the CJEU made a U-turn in its case law as the EBA did between G 1/84, OJ 1985, 299 and G 9/93, OJ 1994, 894.

    It is worth noticing that the CJEU has not decided to make a dynamic interpretation of its own case law.

    Should the UPC ever start its work, its competence in matters of SPC appears limited.

  3. To me the decision makes sense. After all, an SPC is intended to offset the long time needed for clinical trials and regulatory approval. When a known compound is used for a second medical use – and even more so for improved dosing regimes – in most cases the trials and approval will be much faster and much cheaper than for the first medical use. Therefore, there is no need to extend the monopoly in these cases.
