New SPC reference to the CJEU
The CJEU is asked to consider specific aspects of the Neurim test

The Paris Court of Appeal is referring two questions to the CJEU relating to how to apply Article 3(d) of the SPC Regulation in light of specific aspects of the CJEU’s earlier Neurim decision (C-130/11) and the particular facts of the SPC application in suit. According to Neurim, SPCs for new applications of a previously authorised product are available, but patent offices throughout the EU have interpreted the test set out in Neurim in a range of different ways.  The French Court’s first question seeks to clarify the type of new authorisation which qualifies as a new “application” and so benefits from a new SPC under Neurim.  It also seeks to clarify what scope of basic patent is required to meet the test set out in Neurim.

Santen filed an SPC application for the product “ciclosporin eye drop emulsion” based on its patent to oil-in-water ophthalmic emulsions (EP1809237) and an MA for the product Ikervis, which uses this emulsion. The French patent office refused the SPC application for failing to comply with Article 3(d) of the SPC Regulation, noting the existence of an earlier MA to the medicinal product Sandimmun, where the active ingredient, like in Ikervis, is ciclosporin. The decision was appealed to the Paris Court of Appeal.

Santen argued that the earlier authorisation for Sandimmun was not relevant in light of Neurim because it used an oral solution and not the emulsion of the basic patent. Therefore, Santen argued that Ikervis was the “first authorisation” in respect of the ciclosporin emulsion covered by the basic patent. According to Santen, this is consistent with the broad test suggested in Neurim, which limited the relevant authorisations under Article 3(d) to only those that fall within the scope of the basic patent.

Santen also argued that Ikervis is an eye drop emulsion for the treatment of a type of severe keratitis (a disease affecting the cornea of the eye).  Sandimmun, on the other hand, is taken orally for a number of indications including endogenous uveitis (inflammation of the uvea, a part of the eye distinct from the cornea). Santen therefore argued that Ikervis is distinguished from Sandimmun by at least its different method of administration and indication.

Seeking to apply the Neurim jurisprudence in a “measured way”, the French patent office stated that Article 3(d) could be satisfied in this particular case if: (1) the later authorisation relates to an indication that falls within a “new therapeutic field” as compared to the previous MA, or the active ingredient in the later authorised medicinal product has a different mechanism of action; and (2) the scope of the basic patent is “consistent” with the later authorisation (and is therefore “limited” to the new indication). It suggested that neither of these requirements were met for Ikervis, because both Ikervis and Sandimmun were authorised for treatment of inflammation of parts of the eye in humans and worked by the same mechanism of action. In addition, the French patent office suggested that the scope of the basic patent was inconsistent with the Ikervis MA because the claims are not limited to the new authorised indication.

In its decision, the Paris Court of Appeal held that in the context of this particular SPC application the Neurim decision does not provide sufficient detail to interpret what is meant by the phrase “different application” and that it is unclear whether the basic patent must be limited to the new indication of the invoked MA. It therefore referred two questions to the CJEU:

Question 1

  • Should the notion of different application within the meaning of the CJEU Neurim decision of 19 July 2012, C-130/11, be strictly understood, i.e.:
  • be limited to the case of a human application following a veterinary application,
  • or concern an indication in a new therapeutic field, in the sense of a new medical specialty, compared to the previous MA, or a drug in which the active principle exerts an action different from that which it exerts in the drug that was the subject of the first MA;
  • or more generally, in the light of the objectives of Regulation (EC) No 469/2009 aiming at establishing a balanced system taking into account all the interests at stake, including those of public health, be assessed according to more stringent criteria than those used for the assessment of the patentability of the invention;
    or, on the contrary, should it be understood in an extensive way, i.e. including not only different therapeutic indications and diseases, but also different formulations, dosages and/or modes of administration?

Question 2

  • Does the notion of application falling within the scope of protection conferred by the basic patent within the meaning of the CJEU Neurim decision of 19 July 2012, C-130/11, imply that the scope of the basic patent should be consistent with that of the MA invoked and, therefore, limit itself to the new medical use corresponding to the therapeutic indication of said MA?

In attempting to clarify what is intended by “different application”, question 1 asks what sort of a new application of an old active ingredient might be enough to allow a Neurim-style SPC, setting out four options for what might be required. Question 2 focuses on what scope the claims need to have in order to be eligible for an SPC when applying the test set out in Neurim. As a result, the answers to this new referral could provide additional clarity as to when SPCs can be filed for new applications of previously authorised products.
