On 12 May this year, AIM exercised its right to opt the relevant European patent in this case out of the UPC’s jurisdiction. The UPC subsequently became operational on 1 June 2023. AIM withdrew its prior opt-out on 5 July and filed is statement of claim and a preliminary injunction application against Supponer before the Helsinki local division of the UPC on the same day.
However, Supponer challenged the claims raised against it. In particular, it claimed that AIM’s withdrawal of its opt-out was ineffective and so its claims should be dismissed. It cited the fact that national infringement and revocation proceedings in Germany in respect of AIM’s patent were pending before AIM had exercised its right to opt-out, meaning that the UPC had no jurisdiction over the matter.
In agreeing with Supponer’s assessment, the Helsinki court considered provisions in the UPC Agreement (UPCA) and UPC Rules of Procedure (RoP).
Article 83(4) of the UPCA and Rule 5.8 of the RoP provide that an opt-out can be withdrawn unless an action has already been brought before a national court of a UPC contracting member state.
AIM argued, amongst other things, that Article 83(4) UPCA cannot apply to national actions filed before the entry into force of the UPCA on 1 June 2023, and that any other interpretation would be in violation of the Vienna Convention on the law of Treaties (VCLT), in particular the principle of non-retroactivity of international treaties, of which the UPCA is an example. AIM also said that there are different parties in the national and UPC actions and therefore Article 83(4) UPCA cannot apply in this case.
However, the Helsinki court rejected AIM’s arguments, determining that the VCLT requires that “a treaty shall be interpreted in good faith in accordance with the ordinary meaning to be given to the terms of the treaty in their context and in the light of its object and purpose” and that the UPCA was clear and unambiguous as it states that the withdrawal of an opt-out is possible "unless an action has already been brought before a national court...". It considered that there is no limitation or restriction to that wording to the effect that it would only apply to previous national proceedings that have been initiated after 1 June 2023, and said a reading of the RoP further supports that view.
The court therefore found that AIM’s withdrawal of the opt-out was ineffective due to the national proceedings and that the UPC therefore lacks competence to rule on the claims raised against Supponer in respect of the patent at issue.
