Week 44: Res Judicata & National Courts, PI granted, plus CoA on Security for Costs

In this episode (Week 44, 2025), our AI hosts unpack Professor Willem Hoyng’s expert analysis of the latest key UPC rulings.Highlights from this episode include:🔹 Res Judicata from National Courts (LD Munich): In Heraeus v Vibrantz, the UPC respected a German court’s decision as res iudicata, but still allowed a new invalidity argument (Art. 83 EPC) that wasn't raised nationally.🔹 Security for Costs on Appeal (Court of Appeal): A key ruling in Oerlikon v Bhagat. The CoA denied security for first instance costs but granted it for the appeal itself, citing the appellant's refusal to pay.🔹 "Useless" PI against non-appearing defendants? (LD Düsseldorf): In HP v Rentmeister, a PI was granted, but Willem Hoyng questions its value since no ruling was given against the Chinese defendant. He argues Art. 15 of The Hague Convention was overlooked.📖 For the full in-depth written analysis by Prof. Hoyng, click here:https://www.hoyngrokhmonegier.com/news-insights/upc-unfiltered-by-willem-hoyng-upc-decisions-week-44-2025/(Disclaimer: This podcast uses AI-generated voices—minor inaccuracies may occur.)#UPCUnfiltered #UnifiedPatent-Court #PatentLitigation #UPC #CaseLaw #WillemHoyng #LegalTech #PatentLaw #ResJudicata #SecurityForCosts
