If generic producers and the owner of a medicinal product are in a legal dispute and uncertain about the validity of the pharmaceutical patent, is competition discernible? The opinion of Advocate General contains interesting considerations on competition in the pharmaceutical sector.
Validity of the pharmaceutical patent questioned
In the long periods of time it takes to obtain a marketing authorisation for medicinal products, it is not at all uncommon for there to be legal disputes about the validity of the associated patent and invalidity proceedings against the patent.
The ECJ is currently faced with the question of whether a generic drug manufacturer and the owner of a drug patent are to be regarded as potential competitors if they are in dispute over the validity of the pharmaceutical patent – or even if the patent owner has obtained an interim injunction prohibiting the generic drug manufacturer from entering the market until the court proceedings are concluded.
And if, in order to settle the dispute, the parties conclude an agreement in which the generic manufacturer undertakes not to enter the market with its generic product and not to challenge the patent for the duration of the agreement (max. the remaining patent term) – is there then a restriction of competition by object within the meaning of Article 101(1) TFEU? All the more so if the agreement also includes substantial value transfers to the generic company?
In the remarks of the Advocate General (EU:C:2020:28), interesting considerations on existing competition in the pharmaceutical sector can be found despite uncertainty about the legality and validity of a pharmaceutical patent.
The plaintiffs in this litigation are Generics (UK) Ltd, GlaxoSmithKline plc (GSK), Xellia Pharmaceuticals ApS, Alpharma, LLC, formerly Zoetis Products LLC, Actavis UK Ltd and Merck KGaA, and the defendant is the Competition and Markets Authority (UK). In this case, the patent on the active ingredient of a drug had expired and the originator company GSK only held process patents.
Uncertainty about patent infringement = competition not detectable?
In such a situation, from the point of view of patent law, the manufacturers of generic drugs can legally enter the market with generic copies of the original product in two ways, the Advocate General summarised: either with generic copies manufactured according to manufacturing processes which remain protected by patents if these patents are declared invalid, or with generic copies manufactured by other processes, in which case these copies do not constitute an infringement of the manufacturing processes of the original product, which remain protected by patent law.
GSK and also the generic manufacturers argued that the existence of valid and infringed patents is an insurmountable barrier to entry of an original product protected by these patents into the market. However, since it is impossible to know whether generic producers could have entered the market without infringing GSK’s patent rights (if the patent had been invalidated in the invalidity proceedings), it is equally impossible to determine whether there was potential competition between operators.
Advocate General: Uncertainty is a characteristic of competition
The classification of an agreement between undertakings as an agreement that has as its object or effect the restriction of competition therefore presupposes that there is competition that can be restricted, the Advocate General pointed out. The assessment of the conditions of competition on a market is based not only on existing competition between undertakings already active on that market, but also on potential competition between those undertakings and undertakings not yet active on that market. It is therefore necessary to determine whether there are insurmountable barriers to entry in that market, the Advocate General explained.
In the opinion of the Advocate General, the applicants’ assumption is wrong that potential competition between a patent holder of a medicinal product and the manufacturer of a generic product depends on the probability that the generic manufacturer will succeed in a dispute with the holder of the original patent for the medicinal product. On the contrary, uncertainty is a fundamental feature of competitive relations in the pharmaceutical sector, as in all sectors where there are exclusive rights to technologies.
Reference to previous ECJ decisions
He also referred to the Lundbeck v Commission decision, in which the ECJ ruled that it was not necessary to prove with certainty that the generic company had entered the market and that such entry would inevitably have been successful if no distinction was to be made between actual and potential competition, but that it was sufficient to show that the company had real and concrete possibilities in this respect.
Moreover, process patents, irrespective of their validity, do not prevent generic producers from entering the market with a generic product manufactured by other processes, unlike a compound patent, the GA added.
It also referred to the Novartis/Roche decision. The European Court of Justice (ECJ) had made it clear in this decision that the state of uncertainty as to the legality of the conditions for the marketing and prescription of the medicinal product in question did not preclude a competition authority from finding that this product belongs to a particular market and is therefore in competition with the other medicinal product(s) present on that market.
Interim injunction and transfer of value
Even an interim injunction against the generic drug manufacturer does not change this; an interim injunction does not prejudge the final outcome of the current legal dispute, the GA explained in his closing statement.
Furthermore, a value transfer of an amount sufficient to induce this manufacturer to abandon its efforts to enter the market independently would constitute a restriction of competition by object if it became clear that the only consideration for this value transfer was the generic manufacturer’s refusal to enter the market with its product.
