A Danish court has established new criteria for co-inventorship in patent law, ruling that Olin's employees made independent intellectual contributions to wind turbine blade technology developed during their collaboration with Vestas. The decision addresses when parties can claim ownership or co-ownership of patent applications based on knowledge acquired through cooperative relationships.

Sø- og Handelsretten har givet Olin medhold i en tvist mod Vestas om medopfinderskab og medejerskab til patentrettigheder, der udspringer af et forskningssamarbejde om cirkulær genanvendelse af vindmøllevinger.

I dommen har Sø- og Handelsretten taget stilling til, hvad der skal til for at være medopfinder efter dansk ret.

Baggrund

Olin er en global producent og distributør af kemiske produkter, herunder epoxy, og leverer epoxy til Vestas til brug ved produktion af vindmøllevinger.

Tvisten vedrørte 11 internationale patentansøgninger indleveret af Vestas og ét udstedt amerikansk patent. Olin gjorde gældende, at patentrettighederne i hvert fald delvist var baseret på viden og resultater, som parterne havde udviklet i fællesskab som led i deres samarbejde.

GEMA, acting as the collecting society, claimed that OpenAI’s models had memorised and reproduced copyrighted lyrics without permission. Comparable collecting societies across Scandinavia – such as KODA (Denmark) play similar roles in protecting authors’ rights and are closely watching this development.

EPO Enlarged Board Clarifies: Publicly Available Products Are Prior Art, Even If Irreproducible

The European Patent Office's Enlarged Board has fundamentally altered the landscape of prior art assessment, establishing that products made publicly available before a patent filing date constitute prior art regardless of whether they can be analyzed or reproduced. This landmark decision removes the long-standing reproducibility requirement, making market availability alone sufficient to destroy novelty and significantly raising the stakes for timely patent filings.
