- 2026-06-12Infringement ActionÖffentlich
Zusammenfassung: The Local Division Mannheim dismissed Irdeto's infringement action against DJI Europe B.V., DJI GmbH, and Solectric GmbH concerning EP 2 831 787 B1, finding that the claimant failed to prove that the accused DJI drones and controllers make use of the patented methods or systems. The counterclaim for revocation filed by the defendants was also dismissed, as the patent was found valid. Each party was ordered to bear its own costs.

- Infringement of method and system claims for preventing security threats on a device (claims 1-5, 10-12, 14)
- Claim construction of 'abstraction layer', 'secured software agent', 'upcalls', and 'runtime validation' requirements
- Whether dm-verity in DJI drones performs runtime validation as required by claim features 1.2.1-1.2.4
- Whether SELinux alone satisfies the claim requirement for a secured software agent embedded in the abstraction layer
- Validity: added matter under Art. 138(1)(c) EPC / Art. 65(2) UPCA
- Validity: novelty and inventive step
- Counterclaim for revocation
- Costs allocation under Art. 69 UPCA
- 2026-02-27Infringement ActionÖffentlich
Zusammenfassung: The Mannheim Local Division (judge-rapporteur Johansson) ordered Defendant 1 (SZ DJI Technology Co., Ltd.) to pay a separate court fee for its counterclaim for revocation within 14 days, ruling that the fee already paid by Defendants 2-4 for their earlier counterclaim does not cover Defendant 1's subsequently filed separate counterclaim, even if the content is the same. Failure to pay may result in a default decision under R. 355 RoP.

The patent is valid; the counterclaim for revocation is dismissed because the defendants failed to establish invalidity on any of the grounds raised (added matter, novelty, inventive step)
KlägerRechtsgrundlage: Art. 65(2) UPCA; Art. 138(1)(c) EPCdm-verity as implemented in the accused DJI drones and controllers does not perform runtime validation: it operates only at boot time and the claimant failed to prove any runtime validation by dm-verity
BeklagterRechtsgrundlage: Claim features 1.2.1-1.2.4 of EP 2 831 787 B1The claimant's statements on dm-verity in its Statement of Claim were strictly limited to booting and the expert opinion did not relate to the specific implementation in the attacked embodiments
BeklagterRechtsgrundlage: Claim construction; feature 1.2.3 requiring runtime validation
The drones and remote controllers make use of the method defined in claims 1-5 and 10-12 and are systems as defined in claim 14, because SELinux and dm-verity together satisfy all claim features including runtime validation
KlägerRechtsgrundlage: Claims 1-5, 10-12, 14 of EP 2 831 787 B1dm-verity performs validation during runtime because loadable kernel modules may be loaded during runtime and checked by dm-verity
KlägerRechtsgrundlage: Feature 1.2.3 of EP 2 831 787 B1The conditional applications to amend the patent are admissible
KlägerRechtsgrundlage: R. 30 RoP
