    Summary: The Düsseldorf Local Division dismissed Headwater Research LLC's infringement action against Samsung and revoked European patent EP 3 110 069 B1 to the extent of claim 1, on the basis of a successful counterclaim for revocation; all costs were borne by the claimant.

    • Patent revocation on counterclaim

    Infringement ActionPublic

    Summary: Düsseldorf Local Division dismissed Samsung's application for security for costs against Headwater Research LLC under R. 158 RoP. The Court found that while enforcing a cost order against a US-domiciled entity might be more burdensome, the evidence showed Headwater generates recurring revenues from licensing, making the concern about non-recovery insufficiently justified.

    • Security for costs dismissed (R. 158 RoP, Art. 69(4) UPCA)

Plain-English summary

Headwater Research LLC brought an infringement action against Samsung Electronics entities at the Düsseldorf Local Division concerning EP 3 110 069 B1 (device-assisted services for protecting network capacity). The court dismissed the infringement action and revoked claim 1 of the patent by decision of 30 July 2025; before the appeal period expired, Headwater withdrew the action with Samsung's consent, rendering the July 2025 decision ineffective. Each party bears its own costs.

Accepted arguments
What the court agreed with — by party.

  • Counterclaim for revocation of EP 3 110 069 B1 claim 1 is well-founded

    RespondentLegal basis: Art. 65 UPCA

    Note: Samsung's counterclaim for revocation succeeded, with the court revoking EP 3 110 069 B1 to the extent of claim 1 and consequently dismissing the infringement action.

Rejected arguments
What the court did not agree with — and why.

  • Samsung should be ordered to provide security for costs against Headwater

    RespondentLegal basis: R. 158 RoP; Art. 69(4) UPCA

    Reason: The Düsseldorf Local Division dismissed the security-for-costs application because Samsung failed to provide evidence of applicable foreign law or its application, and Headwater demonstrated recurring licensing revenues making insolvency risk insufficient.

  • New line of arguments on added matter based on different passages of a lengthy document should be admitted

    ClaimantLegal basis: Rule 9.2 RoP

    Reason: The court rejected the new added-matter argument under Rule 9.2 RoP because the issue had been raised from the outset but the new argument relied on entirely different passages of a lengthy document, undermining the front-loaded procedure; neither the court nor the other party could be forced to deal with it from scratch.

Key legal principles
Doctrines and rules cited in the reasoning.
security for costs dismissed where defendant fails to evidence that enforcement against US-based claimant would be unduly burdensomerecurring licensing revenues from an NPE can negate insolvency risk for security-for-costs purposesmere status as NPE insufficient to justify security for costswithdrawal of infringement action permissible before appeal period expires where parties consent and have no legitimate interest in appeal (CoA_569/2014 applied)decision on infringement action including costs becomes ineffective upon permitted withdrawal under R. 265 RoPfront-loaded procedure under RoPinadmissibility of late new arguments under Rule 9.2 RoP even on the same broad issuerevocation of patent claim as counterclaim defeats infringement action
