As a general rule, defendants in Spain must be heard before a preliminary injunction request against them can be upheld. Preliminary injunctions can therefore be granted ex parte only in exceptional cases – namely, in cases of urgency or if the hearing could jeopardise the preliminary injunction's aim.
However, in pharmaceutical patent cases, plaintiffs often request ex parte preliminary injunctions and, for some years, many such requests were upheld despite their exceptional nature.
Until recently, it was relatively common for the patent courts to grant preliminary injunctions ex parte. However, in many cases, these same courts would – after hearing the defendants – revoke the preliminary injunction for being groundless. This is precisely what happened in the 2017 cases involving:
In light of this situation, the new Patents Act (which came into force in April 2017) introduced the possibility of filing protective briefs in cases where it is foreseeable that an ex parte preliminary injunction will be requested (the Barcelona patent courts had previously started admitting such briefs despite the fact that they were not expressly contemplated in the law). The main purpose of a protective brief is to avoid a preliminary injunction being granted ex parte. To this end, the future defendant can appear before the court, justify that there is no extreme urgency for the injunction and outline its arguments on the merits of the case.
In order to better understand the usefulness of protective briefs, this article examines some recent cases in which they have proved very effective for the defendants.
In the rituximab case (MabThera), Celltrion and Kern Pharma filed a protective brief to mitigate the risk of Biogen, Roche and Genentech seeking an ex parte preliminary injunction against them for the infringement of two patents, after having received warning letters from the companies. In the protective brief, Celltrion and Kern Pharma argued that there was no extreme urgency for the injunction and outlined the reasons why the patents in question were clearly invalid. The protective brief was admitted by Barcelona Commercial Court Number 4, whose order was formally served on the pre-plaintiffs.
Ultimately, Biogen, Roche and Genentech did not request a preliminary injunction. Instead, they simply filed a main action for infringement of the patents.
Ezetimibe and simvastatine case
In the ezetimibe and simvastatine case (Inegy), Barcelona Commercial Court Number 5 refused to grant the preliminary injunction which MSD had requested ex parte against a number of generics and decided to schedule a hearing to hear the defendants. In its 17 April 2018 order and based on the protective brief previously filed by the defendants, the court concluded that MSD could and should have filed its preliminary injunction request much earlier than it did, as the defendants had informed MSD well in advance about the launch of their generic drugs.
After the hearing, the court definitively dismissed MSD's preliminary injunction request (due to the prima facie invalidity of the asserted supplementary protection certificate (SPC)).
In the darunavir case (Prezista), Searle and Janssen requested an ex parte preliminary injunction against Sandoz for alleged SPC infringement. Sandoz had previously filed a protective brief alerting the court that Searle and Janssen were deliberately delaying their request so as to artificially generate an alleged urgency and obtain the preliminary injunction ex parte.
Barcelona Commercial Court Number 1 refused to prosecute the preliminary injunction request ex parte and summoned the parties to a hearing. In her decision of 6 February 2019, the judge explained that the protective brief had been key in informing the court of the situation and observed that the plaintiff was to blame for the delay in requesting the preliminary injunction when it learned of the defendant's marketing intention.
Following this decision, Searle and Janssen withdrew their preliminary injunction request. As such, the hearing did not take place.
The above precedents show that protective briefs constitute a new tool that can, in certain cases, reduce or even eliminate the risk of an ex parte preliminary injunction and the inconveniences associated therewith. Of course, in practice, whether it is advisable to file a protective brief must be assessed on a case-by-case basis, as this will depend on the specific circumstances of the case at hand.
