Summary

By order of 31 July 2024 (UPC_CFI_330/2024, ACT_36396/2024, ORD_44601/2024), the presiding judge and judge-rapporteur of the Mannheim Local Division held that the steps already taken to bring Panasonic Holdings’ Statement of Claim to the attention of Xiaomi H.K. Limited, based in Hong Kong, constitute good service under Rule 275.2 RoP, in the infringement action on EP 3 096 315. The Hong Kong central authority had returned the documents, objecting to the words « Hong Kong » in the party designation. Separate orders to the same effect were made in other severed proceedings between the same parties.

Question

Must service be attempted again, or an alternative method first tried under Rule 275.1 RoP, where the requested authority definitively refuses service under the Hague Service Convention?

Decision

As the requested authority’s refusal was serious and final, no further transmission is required and the time limit of Art. 15(2)(b) of the Hague Convention does not apply. The request had been transmitted in the required form. The designation « Hong Kong » was the claimant’s choice, and censorship of content on grounds of political expediency has no place under the Convention, nor may the court itself redact the pleadings. As the other routes (representatives in the Munich proceedings, group companies, an email address) were bound to fail, Rule 275.2 RoP applies without a prior attempt under Rule 275.1 RoP. Notice of the order is given on the court’s website.
