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.
