While
we await the CJEU’s judgment (date not yet announced) in Mylan AB v. Gilead
Sciences Finland Oy, Case C-473/22 (see post discussing Advocate General
Szpunar’s opinion here), the Supreme Court of the Netherlands has issued a decision
addressing whether compensation is due for losses suffered during the period of
time a patentee enforced a preliminary injunction concerning a patent that is
later revoked. The case, Menzis
Zorgversekeraar N.V. v. AstraZeneca B.V., is briefly excerpted in this post
on EPLaw, which links to the decision in the original Dutch and in English translation. The patent in suit covered a sustained
release formulation of a drug, quietapine.
(An earlier patent on the immediate release version of the drug expired
in 2012.) The District Court of the Hague
sustained the validity of the sustained release patent in 2012, after which AstraZeneca
obtained a preliminary injunction prohibiting Sandoz from marketing a generic version
of the sustained release formulation in the Netherlands. In
2014, however, the Court of Appeal for the Hague reversed the 2012 judgment and
revoked the Dutch patent for lack of inventive step, following which Astra Zeneca’s
competitors launched their generic versions.
In 2016, Menzis, a health insurer, filed a complaint alleging that
AstraZeneca should be required to compensate Menzis for losses sustained from having
to reimburse insureds for the use of AstraZeneca’s brand-name sustained release
formulation during the time the generic drugs were excluded from the market. The district court ruled for Menzis, but the Court
of Appeal reversed, and the Supreme Court affirms the Court of Appeal.
In
so ruling, the Court of Appeal ruling (which the Supreme Court quotes with
approval) held that “[i] follows from the CFS Bakel/Stork judgment [no citation
provided] that Dutch law conforms to the view - also held in our neighboring
countries - that some form of culpability on the part of the patentee is
required in order to assume liability after the revocation of a patent” (para.
5.2). The Court of Appeal either distinguished
or overruled what I assume to be a previous Netherlands Supreme Court decision,
Ciba Geigy/Voorbraak (paras. 5.7 - .5.8):
In that judgment, the Supreme Court
ruled that, in principle, it should be assumed that the person who, by
threatening enforcement, forced his opposing party to behave in accordance with
an injunction issued in summary proceedings, has acted unlawfully if, as the
judgment on the merits of the case shows with hindsight, he was not entitled to
require the opposing party to refrain from the acts in question. Irrespective
of whether that judgment is consistent with the rules of the European
Enforcement Directive as interpreted in the Court of Justice's judgment in
Bayer/Richter (AstraZeneca disputes that), it does not follow from the Ciba
Geigy/Voorbraak judgment that the patentee has strict liability to others other
than the party who has been forced to comply with an interlocutory injunction
by threat of enforcement. The rationale for this judgment focuses exclusively
on the special position of that opposing party and is based in part on the consideration
that penalties forfeited for failure to comply with the interlocutory
injunction will continue to be forfeited following a contrary judgment on the
merits. The latter strikes a certain balance between the clashing interests.
That balance is lacking when extending strict liability to parties such as
Menzis, which are not liable to forfeit penalties for non-compliance with the
injunction.
. . . [T]he judgment in Ciga Geigy/Voorbraak
is not exclusively based on the provisional nature of a decision in summary
proceedings, but also on (the precisely definitive nature of) the indebtedness
of forfeited penalties. . . .
The
Court of Appeals further correctly concluded that AstraZeneca’s reliance on the
patent during the relevant time period was not unlawful. The standard is whether “AstraZeneca knew, or
should have realized, in that period that a serious, non-negligible chance
existed that the patent would not stand up in opposition or nullity proceedings,”
(para. 5.10), and the Court says no: the
2012 district court decision supported validity, and some other European
countries also upheld the validity, although the English High Court found the
U.K. portion of the patent invalid in 2012.
Finally, the Supreme Court states that, although “the circumstance that
AstraZeneca did not act unlawfully does not automatically imply that the
enrichment alleged by Menzis is justified,” the facts do not support a finding
of unjust enrichment.
One additional notable
thing about this case is that, as stated above, it was the health insurer that
was seeking reimbursement, rather than the excluded generic firms. Except for the fact that the present case
does not involve any allegation of fraud, this situation is reminiscent of Sec’y
of State for Health v. Servier Labs. Ltd., [2021] UKSC 24, in which the
U.K. Supreme Court rejected a claim that the defendants, who allegedly caused
the U.K.’s National Health Service to suffer economic harm by defrauding the
EPO into issuing a patent that later was found to be invalid, could be liable
under the doctrine of “unlawful means.”
The UKSC held that the doctrine does not apply unless the defendant’s
conduct affected the third party’s (EPO’s) freedom to deal with the plaintiff. Here, by contrast, it appears that the Dutch
courts would permit a health insurer to collect reimbursement on the right set
of facts.
