Introduction
The Patent
"1. A composition comprising particles of a solid or liquid, substantially water insoluble pharmacologically active agent, coated with protein, wherein the average diameter of said particles is less than 200 nm, wherein said protein coating has free protein associated therewith, and wherein a portion of said pharmacologically active agent is contained within said protein coating and a portion of said pharmacologically active agent is associated with said free protein.
32. A composition according to any one of claims 1 to 22 for use in eliminating cancer cells, wherein said composition is cremaphor free and said pharmacologically active agent is an antineoplastic.
33. A composition according to claim 32, wherein said antineoplastic is paclitaxel and said protein is albumin."
Nab-paclitaxel
"(i) nab-paclitaxel displays more effectiveness than paclitaxel in treating some tumours either alone or in combination with other anti-cancer agents; (ii) … nab-paclitaxel offers advantages over conventional cremaphor-based formulations of paclitaxel in terms of patient tolerability; (iii) … nab-paclitaxel depletes the tumour microenvironment and kills cells other than cancer cells within it; (iv) … nab-paclitaxel is better than paclitaxel in killing tumour cells in vitro; (v) … nab-paclitaxel is transported particularly effectively to tumour locations and … (vi) nab-paclitaxel remains intact inside the cell."

The SPC Regulation
"[3] Medicinal products, especially those that are the result of long, costly research will not continue to be developed in the Community and in Europe unless they are covered by favourable rules that provide for sufficient protection to encourage such research.
[4] At the moment the period that elapses between the filing of an application for a patent for a new medicinal product and authorisation to place the medicinal product on the market makes the period of effective protection under the patent insufficient to cover the investment put into the research.
[5] This situation leads to a lack of protection which penalises pharmaceutical research.
[6] There exists a risk of research centres situated in the Member States relocating to countries that offer greater protection.
[7] A uniform solution at Community level should be provided for, thereby preventing the heterogeneous development of national laws leading to further disparities which would be likely to create obstacles to the free movement of medicinal products within the Community and thus directly affect the establishment and the functioning of the internal market.
[8] Therefore, the creation of a supplementary protection certificate granted, under the same conditions, by each of the Member States at the request of the holder of a national or European patent relating to a medicinal product for which marketing authorisation has been granted is necessary. A Regulation is therefore the most appropriate legal instrument."
"Article 1
Definitions
For the purpose of this Regulation:
(a) 'medicinal product' means any substance or combination of substances presented for treating or preventing disease in human beings or animals and any substance or combination of substances which may be administered to human beings or animals with a view to making a medical diagnosis or to restoring, correcting or modifying physiological functions in humans or in animals;
(b) 'product' means the active ingredient or combination of active ingredients of a medicinal product;
(c) 'basic patent' means a patent which protects a product as defined in (b) as such, a process to obtain a product or an application of a product, and which is designated by its holder for the purpose of the procedure for grant of a certificate;
…
Article 3
Conditions for obtaining a certificate
A certificate shall be granted if, in the Member State in which the application referred to in Article 7 is submitted and at the date of that application -
…
(b) a valid authorisation to place the product on the market as a medicinal product has been granted in accordance with Directive 2001/83/EC or Directive 2001/82/EC, as appropriate;
…
(d) the authorisation referred to in point (b) is the first authorisation to place the product on the market as a medicinal product.
Article 8
Content of the application for a certificate
1. The application for a certificate shall contain:
…
(b) a copy of the authorisation to place the product on the market, as referred to in Article 3(b), in which the product is identified, containing in particular the number and date of the authorisation and the summary of the product characteristics listed in Article 11 of Directive 2001/83/EC or Article 14 of Directive 2001/82/EC;
…"
Interpretation of the SPC Regulation
"Next, the Court observes that the second sentence of Article 3(2) of Regulation No 1610/96 must be interpreted not solely on the basis of its wording, but also in the light of the overall scheme and objectives of the system of which it is a part (see, by analogy, Case C-292/00 Davidoff [2003] ECR I-389, paragraph 24)."
"41. Those rules are intended to achieve a balance between the various interests at stake in the pharmaceutical sector. Those interests include, on the one hand, the interests of the undertakings and institutions, some of which pursue very cost-intensive research in the pharmaceutical sector and therefore favour an extension of the term of protection for their inventions in order to be able to balance out the investment costs. On the other hand, there are the interests of the producers of generic medicines who, as a consequence of the extension of the term of protection of the active ingredients under patent protection, are precluded from producing and marketing generic medicines. It is also relevant in this connection that, in general, the marketing of generic medicinal products has the effect of lowering the prices of the relevant medicinal products. Against that background, the interests of patients lie between the interests of the undertakings and institutions conducting research and those of the producers of generic medicines. That is because patients have an interest, on the one hand, in the development of new active ingredients for medicinal products, but, on the other, they also have an interest in those products then being offered for sale as cheaply as possible. The same applies to State health systems in general which, in addition, have a particular interest in preventing old active ingredients from being brought onto the market in slightly modified form under the protection of certificates but without genuine innovation and thereby artificially driving up expenditure in the health section.
42. Against the background of that complex situation as regards interests, Regulation 1768/92 sought to achieve a balanced solution taking due account of the interests of all parties. In view of the complexity of that balance of interests, it is necessary to proceed with great caution when making a teleological interpretation of the individual provisions of the regulation."
Interpretation of Articles 1(b) and 3(d): the problems
"11. The proposal for a Regulation therefore concerns only new medicinal products. It does not involve granting a certificate for all medicinal products that are authorized to be placed on the market. Only one certificate may be granted for any one product, a product being understood to mean an active substance in the strict sense. Minor changes to the medicinal product such as a new dose, the use of a different salt or ester or a different pharmaceutical form will not lead to the issue of a new certificate.
12. However, the proposal is not confined to new products only. A new process for obtaining the product or a new application of the product may also be protected by a certificate. All research, whatever the strategy or final result, must be given sufficient protection."
Case law of the CJEU on Articles 1(b) and 3(d)
Pharmacia
"Is the grant of a supplementary protection certificate in a Member State of the Community on the basis of a medicinal product for human beings authorised in that Member State precluded by an authorisation to place the same product on the market as a veterinary medicinal product granted in another Member State of the Community before the date specified in Article 19(1) of the Protection Certificate Regulation, or is the sole determining factor the date on which the product was authorised in the Community as a medicinal product for human beings?"
"49. In my view … the scheme of the Regulation … supports the view that the system of supplementary protection certificates which it establishes does not distinguish between medicinal products for, on the one hand, human use and, on the other hand, veterinary use, whether generally or for the specific purpose of Article 19.
50. In particular, the interpretation which I am suggesting appears consistent with Article 3(c) and (d). Article 3(c) includes as a condition for obtaining a certificate that the product has not already been the subject of a certificate and thus precludes the grant of more than one certificate for a product in a Member State even if it has been authorised as a medicinal product more than once. Article 3(d) includes a further condition that the marketing authorisation covering the product in respect of which a certificate is sought is the first authorisation to place that product on the market as a medicinal product and thus precludes the grant of a certificate on the basis of a second marketing authorisation even if an application for a certificate has not been made on the basis of the first marketing authorisation. Those provisions highlight the significance for the system put in place by the Regulation of the notion of one certificate per product without distinction depending on the number of authorisations. Although the authorisation referred to in Article 3(b) and (d) is the first authorisation in the Member State in which the application for the certificate is made whereas that at issue in Article 19 and the question referred is the first Community authorisation, to my mind the principle underlying Article 3 equally suggests that no distinction should be drawn for the purpose of Article 19 depending on whether the relevant authorisation was for human or veterinary use."
"20. It follows, first, that the decisive factor for the grant of the certificate is not the intended use of the medicinal product and, second, that the purpose of the protection conferred by the certificate relates to any use of the product as a medicinal product without any distinction between use of the product as a medicinal product for human use and as a veterinary medicinal product.
21. Whilst noting that the term 'first marketing authorisation in the Community' must be interpreted in the same way in each of the provisions of the regulation in which it is used, it should be pointed out that, according to the sixth recital in its preamble, that regulation seeks to provide a uniform solution at Community level to the problem of inadequate patent protection, thereby preventing the heterogeneous development of national laws leading to further disparities which would be likely to create obstacles to the free movement of medicinal products within the Community. However, an interpretation such as that proposed by Pharmacia would prevent the realisation of that objective. Under Pharmacia's interpretation, the duration of the protection conferred by the certificate, calculated in accordance with Article 13 of the regulation, might be different for the same product.
22. Lastly, and for the reasons set out in points 41 to 43 and 48 to 50 of the Advocate General's Opinion, it must be found that neither the purpose of Article 19 nor the broad logic of the regulation militate in favour of the interpretation put forward by Pharmacia."
MIT
"1. Does the concept of 'combination of active ingredients of a medicinal product' within the meaning of Article 1(b) of Regulation [1768/92/EEC] mean that the components of the combination must all be active ingredients with a therapeutic effect?
2. Is there a 'combination of active ingredients of a medicinal product' also where a combination of substances comprises two components of which one component is a known substance with a therapeutic effect for a specific indication and the other component renders possible a pharmaceutical form of the medicinal product that brings about a changed efficacy of the medicinal product for this indication (in vivo implantation with controlled release of the active ingredient to avoid toxic effects)?"
"17. In the absence of any definition of the concept of 'active ingredient' in Regulation No 1768/92, the meaning and scope of those terms must be determined by considering the general context in which they are used and their usual meaning in everyday language (see, inter alia, Case 349/85 Denmark v Commission [1988] ECR 169, paragraph 9, and Case C-164/98 P DIR International Film and Others v Commission [2000] ECR I-447, paragraph 26).
18. In this case, it is important to note that it is common ground, as the file in this case shows, that the expression 'active ingredient' is generally accepted in pharmacology not to include substances forming part of a medicinal product which do not have an effect of their own on the human or animal body.
19. In that regard, attention must be drawn to the fact that in point 11 of the Explanatory Memorandum to the Proposal for a Council Regulation (EEC), of 11 April 1990, concerning the creation of a supplementary protection certificate for medicinal products (COM(90) 101 final), to which the French Government referred in its oral observations, it is specified that '[t]he proposal for a Regulation therefore concerns only new medicinal products. It does not involve granting a [SPC] for all medicinal products that are authorised to be placed on the market. Only one [SPC] may be granted for any one product, a product being understood to mean an active substance in the strict sense. Minor changes to the medicinal product such as a new dose, the use of a different salt or ester or a different pharmaceutical form will not lead to the issue of a new [SPC].'
20. Therefore, the definition of 'product' in Article 1(b) of Regulation No 1768/92 does not in any way conflict with that referred to by the Commission in point 11 of that explanatory memorandum.
21. In fact, it is apparent from that memorandum that the pharmaceutical form of the medicinal product, to which an excipient may contribute, as noted by the Advocate General in point 11 of his Opinion and the French Government at the hearing, does not form part of the definition of 'product', which is understood to mean an 'active substance' or 'active ingredient' in the strict sense.
…
25. In the light of the foregoing, the inevitable conclusion is that a substance which does not have any therapeutic effect of its own and which is used to obtain a certain pharmaceutical form of the medicinal product is not covered by the concept of 'active ingredient', which in turn is used to define the term 'product'.
26. Therefore, the alliance of such a substance with a substance which does have therapeutic effects of its own cannot give rise to a 'combination of active ingredients' within the meaning of Article 1(b) of Regulation No 1768/92.
27. The fact that the substance without any therapeutic effect of its own renders possible a pharmaceutical form of the medicinal product necessary for the therapeutic efficacy of the substance which does have therapeutic effects cannot invalidate that interpretation.
28. As shown by paragraphs 6 and 7 of this judgment, carmustine is an active ingredient which must be combined with other substances, in particular inert excipients, to be therapeutically effective. More generally, as observed by the Advocate General in point 11 of his Opinion and by the French and Netherlands Governments, it is apparently not unusual for substances which render possible a certain pharmaceutical form of the medicinal product to influence the therapeutic efficacy of the active ingredient contained in it.
29. Thus, a definition of 'combination of active ingredients of a medicinal product' which includes a combination of two substances, only one of which has therapeutic effects of its own for a specific indication, the other rendering possible a pharmaceutical form of the medicinal product which is necessary for the therapeutic efficacy of the first substance for that indication, might, on any view, create legal uncertainty in the application of Regulation No 1768/92, as the French Government pointed out at the hearing. Whether a substance without any therapeutic effect of its own is necessary for the therapeutic efficacy of the active ingredient cannot, in this case, be regarded as a sufficiently precise test.
30. Moreover, such a definition is liable to prevent the attainment of the objective referred to in the sixth recital in the preamble to Regulation No 1768/92, in the words of which a uniform solution at Community level should be provided for, thereby preventing the heterogeneous development of national laws leading to further disparities which would be likely to create obstacles to the free movement of medicinal products within the Community and thus directly affect the establishment and the functioning of the internal market.
31. In those circumstances, the answer to the questions referred must be that Article 1(b) of Regulation No 1768/92 must be interpreted so as not to include in the concept of 'combination of active ingredients of a medicinal product' a combination of two substances, only one of which has therapeutic effects of its own for a specific indication, the other rendering possible a pharmaceutical form of the medicinal product which is necessary for the therapeutic efficacy of the first substance for that indication."
Yissum
"In a case in which the basic patent protects a second medical application of a therapeutic agent, what is meant by 'product' in Article 1(b) of the Regulation and in particular does the application of the therapeutic agent play any part in the definition of 'product' for the purpose of the Regulation?"
"17. It is clear from Massachusetts Institute of Technology, and, in particular, from paragraphs 19, 21, 23 and 24 of that judgment, that the concept of 'product' referred to in Article 1(b) of Regulation No 1768/92 must be interpreted strictly to mean 'active substance' or 'active ingredient'.
18. It follows that the concept of 'product' cannot include the therapeutic use of an active ingredient protected by a basic patent.
19. Moreover, the same interpretation can be inferred from paragraph 20 of the judgment in Case C-31/03 Pharmacia Italia [2004] ECR I-10001, in which the Court held that 'the decisive factor for the grant of the certificate is not the intended use of the medicinal product and … the purpose of the protection conferred by the certificate relates to any use of the product as a medicinal product without any distinction between use of the product as a medicinal product for human use and as a veterinary medicinal product'.
20. Consequently, the answer to the question referred must be that Article 1(b) of Regulation No 1768/92 is to be interpreted as meaning that in a case where a basic patent protects a second medical use of an active ingredient, that use does not form an integral part of the definition of the product."
Neurim
"1. In interpreting Art.3 of Regulation EEC No. 1768/92 [now Regulation (EC) No. 469/2009 ] ('the SPC Regulation'), when a marketing authorisation (A) has been granted for a medicinal product comprising an active ingredient, is Art.3(d) to be construed as precluding the grant of an SPC based on a later marketing authorisation (B) which is for a different medicinal product comprising the same active ingredient where the limits of the protection conferred by the basic patent do not extend to placing the product the subject of the earlier MA on the market within the meaning of Art.4 ?
…
3. Are the answers to the above questions different if the earlier marketing authorisation has been granted for a veterinary medicinal product for a particular indication and the later marketing authorisation has been granted for a medicinal product for human use for a different indication?"
"28. We consider that Neurim's arguments are not only tenable: in our view they are right. Many kinds of valuable pharmaceutical research will not get the encouragement or reward they deserve if they are not. Pharmaceutical research is not confined to looking for new active compounds. New formulations of old active substances are often sought. Most are unpatentable but from time to time a real invention is made and patented.
29. Moreover there is much endeavour to find new uses for known active ingredients. The European Patent Convention 2000 has indeed made the patenting of inventions in this area clearer. Its effect is that a patent for a known substance or composition for use in a method of treatment is not to be regarded as old (and hence unpatentable) unless use for that method is known. It would be most unfortunate if second medical use patents could not get the benefit of an SPC."
(As counsel for Abraxis also pointed out, in this respect Jacob LJ was echoing what he had previously said in Generics (UK) Ltd v Daiichii Pharmaceuticals Co Ltd [2009] EWCA Civ 646, [2009] RPC 23 at [79] citing his own earlier observations at first instance in Draco's Application [1996] RPC 417 at 439.)
"23. The reason given for the adoption of the SPC Regulation is the fact that the period of effective protection under the patent is insufficient to cover the investment put into pharmaceutical research and the regulation thus sought to make up for that insufficiency by creating an SPC for medicinal products (see Medeva, paragraph 31, and Georgetown University and Others, paragraph 25).
24. It is apparent from paragraph 29 of the explanatory memorandum to the proposal for a Council Regulation (EEC) of 11 April 1990, concerning the creation of a supplementary protection certificate for medicinal products (COM(90) 101 final), that, like a patent protecting a 'product' or a patent protecting a process by which a 'product' is obtained, a patent protecting a new application of a new or known product, such as that at issue in the main proceedings, may, in accordance with Article 2 of the SPC Regulation, enable an SPC to be granted and, in that case, in accordance with Article 5 of the regulation, the SPC confers the same rights as conferred by the basic patent as regards the new use of that product, within the limits laid down by Article 4 of that regulation (see, by analogy, Medeva, paragraph 32, and order of 25 November 2011 in Case C-630/10 University of Queensland and CSL, ECR I-0000, paragraph 38).
25. Therefore, if a patent protects a therapeutic application of a known active ingredient which has already been marketed as a medicinal product, for veterinary or human use, for other therapeutic indications, whether or not protected by an earlier patent, the placement on the market of a new medicinal product commercially exploiting the new therapeutic application of the same active ingredient, as protected by the new patent, may enable its proprietor to obtain an SPC, the scope of which, in any event, could cover, not the active ingredient, but only the new use of that product.
26. In such a situation, only the MA of the first medicinal product, comprising the product and authorised for a therapeutic use corresponding to that protected by the patent relied upon for the purposes of the application for the SPC, may be considered to be the first MA of 'that product' as a medicinal product exploiting that new use within the meaning of Article 3(d) of the SPC Regulation.
27. In the light of all the above considerations, the answer to the first and third questions is that Articles 3 and 4 of the SPC Regulation are to be interpreted as meaning that, in a case such as that in the main proceedings, the mere existence of an earlier MA obtained for a veterinary medicinal product does not preclude the grant of an SPC for a different application of the same product for which an MA has been granted, provided that the application is within the limits of the protection conferred by the basic patent relied upon for the purposes of the application for the SPC."
GSK
"1. Is an adjuvant which has no therapeutic effect on its own, but which enhances the therapeutic effect of an antigen when combined with that antigen in a vaccine, an 'active ingredient' within the meaning of Article 1(b) of [the SPC Regulation]?
2. If the answer to question 1 is no, can the combination of such an adjuvant with an antigen nevertheless be regarded as a 'combination of active ingredients' within the meaning of Article 1(b) of [the SPC Regulation]?"
"35. Those considerations also apply to a situation such as that in the main proceedings, in which an adjuvant is in issue which, as it has no therapeutic effects on its own, cannot be regarded as an 'active ingredient' within the meaning of Article 1(b) of Regulation No. 469/2009 .
36. That distinction between 'active ingredient' and 'adjuvant' is also made quite clear in s.3.2.2.1 of Part 1, entitled 'Standardised marketing authorisation dossier requirements', of Annex I to Directive 2001/83, as amended by Directive 2003/63. That annex lists the particulars and documents to be submitted in support of an MA application in accordance, inter alia, with Article 8(3) of that directive, as amended.
37. Section 3.2.2.1 states as follows:
'A description of the finished medicinal product and its composition shall be provided. The information shall include the description of the pharmaceutical form and composition with all the constituents of the finished medicinal product, their amount on a per-unit basis, the function of the constituents of:
– the active substance(s),
– the constituent(s) of the excipients, whatever their nature or the quantity used, including colouring matter, preservatives, adjuvants, stabilisers, thickeners, emulsifiers, flavouring and aromatic substances, etc.,
– the constituents, intended to be ingested or otherwise administered to the patient, of the outer covering of the medicinal products (hard capsules, soft capsules, rectal capsules, coated tablets, films-coated tablets, etc.).
…'
38. Thus, in Directive 2001/83, as amended by Directive 2003/63, the concepts of 'active substance' and 'adjuvant' are clearly distinct and that also holds, in the context of Regulation No. 469/2009, for the concept of 'active ingredient', which cannot, as such, include an adjuvant."
"43. With regard to the judgment in Neurim Pharmaceuticals (1991), it should be noted that in that judgment, as suggested by the Court of Appeal (England and Wales) (Civil Division), the Commission and Advocate General Trstenjak in her Opinion in the case giving rise to that judgment, the Court held, inter alia, at 24 of the judgment, that, like a patent protecting a 'product' or a patent protecting a process by which a 'product' is obtained, a patent protecting a new application of a new or known product may now, in accordance with Article 2 of Regulation No. 469/2009, enable an SPC to be granted and, in that case, in accordance with Article 5 of that regulation, the SPC confers the same rights as conferred by the basic patent as regards the new use of that product, within the limits laid down by Article 4 of that regulation.
44. However, the Court did not, in that judgment, cast doubt on the principle that Article 1(b) of Regulation No. 469/2009 is to be interpreted narrowly, as held in the judgment in Massachusetts Institute of Technology, to the effect that the term 'product' cannot cover a substance which does not correspond to the definition of 'active ingredient' or that of 'combination of active ingredients'."
Forsgren
"1. Under Article 1(b) and Article 3(a) and (b) of [the SPC Regulation], provided that the other conditions are met, may [an SPC] be granted for an active ingredient protected by a basic patent (in this case, Protein D) where that active ingredient is present in a medicinal product (in this case, Synflorix) as part of a covalent (molecular) bond with other active ingredients but none the less retains an effect of its own?
2. If Question 1 is answered in the affirmative:
(a) Under Article 3(a) and (b) of [the SPC Regulation], may [an SPC] be granted for the substance protected by the basic patent (in this case, Protein D) where that substance has a therapeutic effect of its own (in this case, as a vaccine against the Haemophilus influenzae bacterium) but the marketing authorisation for the medicinal product does not relate to that effect?
(b) Under Article 3(a) and (b) of [the SPC Regulation], may [an SPC] be granted for the substance protected by the basic patent (in this case, Protein D) where the marketing authorisation describes that substance as a 'carrier' for the actual active ingredients (in this case, pneumococcal polysaccharides), where the substance, as an adjuvant, enhances the effect of those substances, but where that effect is not expressly mentioned in the marketing authorisation for the medicinal product?"
"23. '[P]roduct' is defined in Article 1(b) of Regulation No 469/2009 as 'the active ingredient or combination of active ingredients of a medicinal product'. However, the term 'active ingredient' is not defined in that regulation. That term also appeared in Article 1(b) of Council Regulation (EEC) No 1768/92 of 18 June 1992 concerning the creation of a supplementary protection certificate for medicinal products (OJ 1992 L 182, p. 1), which was repealed by Regulation No 469/2009, and a question relating to that provision has already been referred to the Court. The Court held on that occasion that it is generally accepted in pharmacology that the term 'active ingredient' does not cover substances forming part of a medicinal product which do not have an effect of their own on the human or animal body (see judgment in Massachusetts Institute of Technology, EU:C:2006:291, paragraph 18).
24. That interpretation was subsequently reproduced, in essence, by the EU legislature. Directive 2011/62/EU of the European Parliament and of the Council of 8 June 2011 (OJ 2011 L 174, p. 74) amended Article 1 of Directive 2001/83 to the effect that the term 'active substance' — which must be understood as meaning 'active ingredient' (judgment in Massachusetts Institute of Technology, EU:C:2006:291, paragraph 21) — is defined therein as 'any substance or mixture of substances intended to be used in the manufacture of a medicinal product and that, when used in its production, becomes an active ingredient of that product intended to exert a pharmacological, immunological or metabolic action with a view to restoring, correcting or modifying physiological functions or to make a medical diagnosis'.
25. It follows that the term 'active ingredient', for the purposes of applying Regulation No 469/2009, concerns substances producing a pharmacological, immunological or metabolic action of their own. Since Regulation No 469/2009 does not draw any distinction according to whether an active ingredient is covalently bound with other substances, it is not appropriate to exclude, on that ground, the grant of an SPC for such an active ingredient.
26. On the other hand, the Court has held that a substance which has no therapeutic effect of its own and which is used to obtain a certain pharmaceutical form of the medicinal product is not covered by the term 'active ingredient' and, consequently, cannot give rise to the grant of an SPC (judgment in Massachusetts Institute of Technology, EU:C:2006:291, paragraph 25).
27. The answer to the question whether a substance which is part of a medicinal product is an active ingredient within the meaning of Article 1(b) of Regulation No 469/2009 depends, therefore, on whether that substance has a pharmacological, immunological or metabolic action of its own, independently of any covalent binding with other active ingredients.
28. Accordingly, the answer to Question 1 is that Articles 1(b) and 3(a) of Regulation No 469/2009 must be interpreted as not precluding, in principle, the possibility that an active ingredient can give rise to the grant of an SPC where the active ingredient is covalently bound to other active ingredients which are part of a medicinal product."
"51. It is appropriate, consequently, to refer to the fundamental objective of Regulation No 469/2009, which is to ensure sufficient protection to encourage pharmaceutical research, which plays a decisive role in the continuing improvement in public health (judgment in Georgetown University and Others, EU:C:2011:776, paragraph 24 and the case-law cited).
52. In addition, as can be seen in particular from subparagraphs 4 and 5 of paragraph 28 of the Explanatory Memorandum to the Proposal for a Council Regulation (EEC) of 11 April 1990, concerning the creation of a supplementary protection certificate for medicinal products [COM(90) 101 final], the protection conferred by an SPC is largely intended to cover the cost of research leading to the discovery of new 'products'.
53. In the light of the wording and purpose of Regulation No 469/2009, it must be held that Article 1(b) of that regulation does not permit an 'active ingredient' to be categorised as a carrier protein conjugated with a polysaccharide antigen by means of a covalent binding, unless it is established that it produces a pharmacological, immunological or metabolic action of its own. Ultimately, it is for the referring court to determine, in the light of all the facts of the dispute on which it is required to rule, whether, on the basis of those criteria, Protein D, conjugated with pneumococcal polysaccharides which form part of Synflorix, produces a pharmacological, immunological or metabolic action of its own, and whether that effect falls within the therapeutic indications covered by the wording of the marketing authorisation.
54. In view of all the foregoing, the answer to Question 2(b) is that Article 1(b) of Regulation No 469/2009 must be interpreted as meaning that a carrier protein conjugated with a polysaccharide antigen by means of a covalent binding may be categorised as an 'active ingredient' within the meaning of that provision only if it is established that it produces a pharmacological, immunological or metabolic action of its own which is covered by the therapeutic indications of the marketing authorisation, a matter which it is for the referring court to determine, in the light of all the facts of the dispute in the main proceedings."
Article 1(b)
Summary of Abraxis' contentions
i) nab-paclitaxel is a single active ingredient, rather than a combination of an active ingredient with an excipient or adjuvant, and it is a different active ingredient to paclitaxel, because in nab-paclitaxel paclitaxel is tightly bound to albumin, and this has important therapeutic consequences;ii) accordingly, nab-paclitaxel is a different "product" to paclitaxel within the meaning of Article 1(b), from which it follows that the Application complies with Article 3(d) because the Abraxane MA is the first authorisation to place nab-paclitaxel on the market;
iii) this conclusion is supported by the practice of the UK Intellectual Property Office of granting SPCs for pro-drugs (active ingredients which have been modified by the substitution of a covalently-bonded chemical group, usually with the purpose of improving its bioavailability) and PEGylated proteins (therapeutic proteins which have been modified by the addition of a polyethyleneglycol (PEG) moiety, again by covalent bonding, usually in order to prevent renal clearance, leading to a longer period of action) (Abraxis also relies upon an SPC granted in relation to a lipid complex product, but this was a long time ago and the facts are not entirely clear);
iv) it is also supported by a teleological interpretation of Article 1(b), since the purpose of the SPC Regulation is to compensate patent proprietors where the effective period of their monopoly is reduced by the time taken to obtain marketing authorisations for products protected by their patents, and hence to reward invention;
v) Abraxis accepts, however, that it is not clear that Article 1(b) should be interpreted as having the effect that nab-paclitaxel is a single active ingredient.
Summary of the Comptroller's contentions
i) the hearing officer found as a fact that nab-paclitaxel is not a single active ingredient, rather it is a combination of an active ingredient, namely paclitaxel, with a substance that is not an active ingredient, namely albumin, albeit that the latter is tightly bound to the former in the nanoparticles;ii) this conclusion is supported by the terms of the Abraxane MA, the SmPC at Annex I of which identifies the composition in section 2 as "paclitaxel formulated as albumin bound nanoparticles" and the labelling at Annex III of which identifies the active substance in section 2 in precisely the same way, and of the EPAR for Abraxane which states in section 2.1 that "Abraxane is a cremaphor-free colloidal suspension of paclitaxel and human serum albumin. Abraxane is a new formulation developed to overcome the water insolubility of the active component paclitaxel …" and in section 2.2 that "Paclitaxel is a known active substance described in the Ph.Eur. and the USP";
iii) nab-paclitaxel stands in a different position to prodrugs and PEGylated proteins, both of which constitute different molecules to the drugs and proteins from which they are derived, and hence different active ingredients and different products, as can be seen from the marketing authorisations and SPCs in question;
iv) the law is clear and there is no need for a reference.
Analysis
Article 3(d)
Summary of Abraxis' contentions
i) the CJEU held in Neurim that Article 3(d) was to be interpreted as meaning that the authorisation referred to in Article 3(b) was the first relevant authorisation, i.e. the first authorisation within the scope of the basic patent, to place the product on the market as a medicinal product;ii) although Neurim was a case about a new therapeutic use of an old active ingredient, as Jacob LJ indicated in the judgment of the Court of Appeal at [28], the same policy considerations apply to a new formulation of an old active ingredient;
iii) Abraxis accepts, however, that it is not clear from Neurim that Article 3(d) should be interpreted in the same way in the case of a new formulation of an old active ingredient.
Summary of the Comptroller's contentions
i) the CJEU's decision in Neurim is confined to new therapeutic uses of old active ingredients;ii) by contrast with its decision in Neurim, the CJEU has made it clear in MIT, GSK and Forsgren that SPCs cannot be obtained for new therapeutic formulations of old active ingredients;
iii) this distinction reflects the distinction drawn in paragraphs 11 and 12 of the Explanatory Memorandum.
Analysis
"Is Article 3(d) of the SPC Regulation to be interpreted as permitting the grant of an SPC where the marketing authorisation referred to in Article 3(b) is the first authorisation within the scope of the basic patent to place the product on the market as a medicinal product and where the product is a new formulation of an old active ingredient?"
