UPC Choice of Law Principles for Damages

Last week the Mannheim Division of the UPC published its decision in Hurom Co. v. NUC Electronics Europe GmbH, establishing some choice of law principles for patent infringement actions filed in the UPC.  There has already been some discussion of the case on JUVE Patent and on ip fray.  The principal question of interest is whether UPC law or national law applies with respect to damages, especially where the infringement is ongoing in the sense that it began prior to the UPC startup date of June 1, 2023 and continued thereafter.  The court’s summary of the decision states, in relevant part, the following:

3. . . . with regard to the determination whether substantive law as laid down in the UPCA or substantive national laws of the UPCA member states applies to acts allegedly infringing traditional European bundle patents, the following applies:

 

a) to acts committed after the entry into force of the UPCA, the substantive law as laid down in the UPCA applies;

 

b) to acts committed before the entry into force of the UPCA, the substantive national laws apply;

 

c) to ongoing acts started before the entry into force of the UPCA and continued after the entry into force on 1 June 2023, the substantive law as laid down in the UPCA applies.

 

4. When assessing whether infringing acts are in that sense “ongoing” and justify the application of the UPCA as a general rule, an overly formalistic approach which runs counter to the aims of the Agreement must not be applied. What is decisive is to categorize such acts not in a formalistic manner which only takes into account, if, when viewed from a pure natural perspective, such acts can be referred to as separable acts, but which looks at the scenario from a normative and therefore evaluative perspective. Before this backdrop it is justified to apply the UPCA as a harmonized set of national law of the contracting member states of the UPCA to ongoing acts, if the infringer continues its infringing behaviour although he could have stopped the infringement in the light of the entry into force of the new regime on 1 June 2023. In that case, however, each party reserves the right to rely on provisions of the national laws for acts before 1 June 2023 being favourable to its position compared to the provisions of the UPCA and the RoP. The party which advances the argument based on national law has to elaborate on such rules of national law and set out with a sufficient degree of substantiation why that rule of national law supports its argument.

 

5. With regard to a right to information, the question of intertemporal applicability and the question of the scope of the period, for which information has to be provided, have to be distinguished. The rights to information provided by the UPCA as laid down in particular in Art. 67 UPCA and Art. 68 (3) (a) (b) UPCA in conjunction with R. 191 sentence 1 alternative 2 RoP are to interpreted to encompass time periods which resided before the entry into force of the UPCA.

Here are a few things that I found interesting.

First, the court concludes that a permanent injunction is appropriate only in the UPC member states in which the patent in suit has been infringed, not the entire UPC (paras. 107-08).

Second, if I am reading this correctly the court implicitly characterizes the law of damages as “substantive” rather than “procedural.”  Under general principles of private international law, as I understand them, even when court concludes that it should apply another state’s substantive law to a particular issue, it usually applies its own procedural law.  But damages law sort of straddles the border between procedure and substance, and there are differing views of whether it should be classified as one or the other.  (See, e.g., the sources I cite in my article Extraterritorial Damages in Copyright Law, 74 Fla. L. Rev. 123, 163 n.204 (2022).)  My own view is that it makes more sense to classify them as substantive, so that if the court is adjudicating foreign patent rights—as courts within the E.U. may have to do now following the Court of Justice’s decision last month in BSH Hausgeräte GmbH v. Electrolux AB, Case C‑339/22—it would apply the foreign state’s damages law.  (That issue will be addressed in this case at a later proceeding, as it relates to damages for the infringement of non-UPC member state patents.  See decision para. 45.)  So I think the UPC is right to conclude that UPC damages law applies to infringement occurring after June 1, 2023, and national damages law to infringements occurring before.  For infringements that span that date, I’m inclined to think that it makes sense to apply UPC law as a default, though as the court indicates, subject to permitting the patent owner and the defendant to argue for more favorable treatment under domestic law.  On the other hand, the right of information is more clearly procedural, and therefore applies to UPC actions involving infringements occurring both before and after the UPC’s entry into force.  Interestingly, the court explicitly characterizes the right to recall and removal of infringing goods from the channels of commerce as substantive (para. 129).

Third, there are a variety of other remedial issues the court briefly addresses, among them (1) the court accepts that injunctive relief is not mandatory but rather may be limited by the principal of proportionality, but here there is no evidence of disproportionality (para. 113); (2) the possibility of damages for moral prejudice is not excluded by virtue of the plaintiff calculated the amount of interim damages it wanted as a reasonable royalty, but there is no evidence here of any such damages having been suffered (para. 119); (3) there is no basis here to award interim damages, to order publication of the decision, to exclude an interim award of costs because the plaintiff didn’t first send a warning letter, or to order security for enforcement pending appeal (paras. 120, 130-35); (4) the fact that the destruction of the infringing goods will have environmental effects is not, by itself, sufficient to reject an order for destruction (para. 126); and (5) damages for pre-grant use of the patent in suit may be available under German domestic law, para. 118 and operational portion B.1).
