Summary

By procedural order of 14 April 2025 (UPC_CFI_119/2025, ACT_7567/2025, ORD_16018/2025), Presiding Judge Zigann, acting as judge-rapporteur of the Munich Local Division, held that the statement of claim filed by Shanghai Jinko Green Energy Enterprise Management and Zhejiang Jinko Solar, in their infringement action on EP 4 372 829 against LONGi Solar Technologie and five other defendants, was deemed served by registered letter on Soltech Energy (Defendant 4) on 14 March 2025. Its statement of defence is due by 16 June 2025. The order treats an uncollected letter as a refusal.

Question

Does a registered letter that was notified but never collected from the post office amount to service under Rule 271.6(b), or must an alternative method of service under Rule 275, sought in the alternative, be ordered?

Decision

Under Rule 271.6(b), a registered letter is deemed served on the tenth day following posting, and service is effective even if acceptance of the letter has been refused. Informed on 10 March 2025 that the item was available at Deutsche Post, the defendant neither collected it within two weeks nor later enquired about it: acceptance was therefore refused. No notification under Rule 271.8 having been filed, the statement of claim was deemed served on the tenth day after posting on 4 March 2025, that is on 14 March 2025.

Key points for practice

Failure to collect a notified registered letter is treated as refusal of acceptance, which does not prevent deemed service on the tenth day after posting.
A claimant whose letter comes back uncollected may seek a finding to that effect before turning to Rule 275.
