PATENT AT ISSUE:
European patent n° EP 4 252 857

PANEL/DIVISION:
Panel of the Local Division in Düsseldorf

DECIDING JUDGES:
This Order was issued by Presiding Judge Thomas, Legally Qualified Judge Dr Thom, Legally Quali-fied Judge Kupecz and Technically Qualified Judge Dorland-Galliot.

LANGUAGE OF THE PROCEEDINGS: English

SUBJECT OF THE PROCEEDINGS: Stay proceedings – R. 295 (m) RoP

REQUESTS OF THE PARTIES:
The Claimants request,
pursuant to Rule 295(m) of the Rules of Procedure (“RoP”), that the Court orders that the infringement proceedings are stayed immediately pending the outcome of the appeal against the first instance decision ORD_598583/2023 of the LD Düsseldorf in the infringement proceedings UPC_CFI_505/2024, ACT_597355/2023 in relation to patent EP 3 536 712 (“EP712”).
The Defendants request,
to reject Claimants’ request to stay the infringement proceedings UCP_CFI_195/2025, ACT_10334/2025.

GROUNDS OF ORDER:
The Court orders to stay the proceedings for the following reasons:
The Claimants base their request on the statement that the question of infringement of EP 857 involves the same factual and legal questions as the case UPC_CFI_505/2024 in relation to EP 712. Under these circumstances, the Court finds that the stay of the proceedings is in accordance with the requirements of proper administration of justice.
If there are no significant differences regarding the infringement issue, it is likely that the Court will also dismiss this claim. Against this background, it is reasonable to conserve the Court's and the parties' resources until the Court of Appeal has made its decision. If the appeal is unsuccessful, the Claimant can still withdraw the claim, meaning that neither party will have spent more time or money than necessary. Contrary to the opinion of the Defendants, the Court sees no conflict between the fundamental right to an effective legal remedy and a fair and public hearing within a reasonable time and the principles of proportionality, flexibility, fairness and equity (Art. 41(3) and 42 UPCA; Art. 6 of the European Convention for the Protection of Human Rights and Fundamental Freedoms). At this point in time, no (permanent) injunction has been granted against the Defend-ants. If the appeal is successful, it is reasonable and fair that the Claimants have a chance to pre-sent new legal arguments and that the Defendants still have the stage of first instance to demonstrate why this case should be approached differently to UPC_CFI_505/2024. In the view of efficiency the stay also effects the counterclaim for revocation.

ORDER:
The infringement action and the counterclaim for revocation (ACT_10334/2025; CC_29742/2025) are stayed pending the outcome of the appeal against the first instance decision ORD_598583/2023 of the Local Division Düsseldorf in the infringement proceedings UPC_CFI_505/2024, ACT_597355/2023 relating to patent EP 3 536 712 (“EP712”).
