Bringing enforcement proceedings while an appeal is still pending risks liability for defendant’s costs

Case Summary

The Court of Appeal held that setting aside a first-instance decision granting relief subject to recurring penalties generally has retroactive effect. Any penalty fees already paid will be refunded by the Court. The value of proceedings is determined by the interest of the party that brought the action. This is not changed as a result of an appeal. A claimant bringing enforcement proceedings while an appeal is still pending does so at its own risk and may be liable for the defendant's costs related to the enforcement proceedings.

Kodak v. Fujifilm

UPC-CoA-28/2026, decision of 3 August 2026

Background

The appeal concerned orders1 made by the Mannheim Local Division in January 2026 requiring Kodak to pay penalties totalling €1.72 million for alleged non-compliance with orders made following a finding that Kodak infringed Fujifilm’s patent.

In the main proceedings, however, the Court of Appeal subsequently set aside2 the infringement decision and held that Kodak did not infringe because it could rely on a private prior-use right. The enforcement appeal therefore focused on the consequences of that reversal for the penalty orders, repayment, the value of the enforcement proceedings and costs.

Retroactive effect and repayment of penalties

In NanoString v 10x Genomics3 , the Court of Appeal held that revocation under Article 75(1) UPCA and Rule 242.1 RoP of a first-instance order granting a provisional injunction generally has retroactive effect. The revoked order is treated as never having had legal effect, so its revocation removes the basis for a later decision imposing penalties for alleged breaches, including breaches predating revocation of the order.

The Court confirmed that the same principle applies where a merits decision imposing obligations subject to recurring penalties is set aside on appeal. Because the underlying infringement decision was retrospectively deprived of legal effect, the penalty orders had no legal basis. The Court set them aside and ordered repayment by the Court of the penalties already paid by Kodak.

Value of the enforcement proceedings

The remaining issues were the value of the enforcement proceedings and responsibility for legal costs and other expenses under Article 69 UPCA.

Kodak submitted that the proceedings should be valued at no less than €1.72 million, corresponding to the penalties imposed. Fujifilm argued for €1 million, reflecting its interest in compliance with the ancillary orders in the underlying action.

The Court held that Rule 370.6 RoP requires an assessment of the objective interest pursued by the party that initiated the action at first instance. Although the value on appeal may differ from the first-instance value, an appeal by the defendant does not shift the relevant perspective to the defendant’s interest in having the decision set aside.

Accordingly, Fujifilm’s interest remained decisive because it had initiated both the infringement action and the related enforcement proceedings. The fact that Kodak brought the appeal did not alter that conclusion.

The penalties themselves did not measure Fujifilm’s interest: they were payable to the Court and included coercive and punitive elements. The relevant interest was instead Fujifilm’s interest in proper performance of the obligations that the penalties were intended to incentivise. As Kodak did not dispute that this interest amounted to €1 million, the Court adopted that figure.

Costs

Because Fujifilm’s infringement claims and the associated orders had been set aside, the Court treated Fujifilm as the unsuccessful party under Article 69(1) UPCA and ordered it to bear Kodak’s reasonable and proportionate legal costs and other expenses of the enforcement proceedings at both first instance and on appeal.

The Court rejected Fujifilm’s argument that Kodak’s conduct during enforcement justified a different costs order. Once the underlying decision was treated as never having had legal effect, Kodak was retrospectively under no obligation to comply with it. There was therefore no basis for finding that Kodak had complied late or incompletely, or that its conduct had unnecessarily increased the costs.

The Court also reiterated that a party enforcing a decision while an appeal is pending does so at its own risk, consistently with Rule 354.2 RoP. This decision (as well as that in NanoString v 10x Genomics) illustrates the risk that a claimant runs in enforcing an order that remains subject to appeal.

Recent Case Reports

No language change at Central Division
08 October 2026
Proceedings before the UPC Central Division must be conducted in the language in which the patent was granted. There is no legal basis to change that language. In a revocation action concerning a German-language patent, the Paris Central Division rejected a request to switch the language of proceedings to English, and also rejected a subsidiary request to allow written submissions in English and hold the hearing in English, holding that Article 49(6) UPCA permits no derogation and reflects a deliberate legislative choice.
Criteria for obtaining an order to produce evidence under Rule 190
07 October 2026
This appeal judgment clarifies that Rule 190 orders to produce evidence require three cumulative conditions: specificity, necessity and proportionality, and cannot be used for fishing expeditions. The Court of Appeal confirmed that first instance judges enjoy a broad margin of discretion when assessing such requests, and upheld the order requiring production of two fabric samples for ballistic testing. Both the appeal and the cross-appeal were dismissed.
Court of Appeal focuses on the technical effect to determine added matter
30 September 2026
The Court of Appeal provided guidance on their approach to assessing added subject matter, highlighting that the technical effect underlying the invention and how the claimed and unclaimed features contribute thereto is central to the analysis.
