Mees van Vondelen obtained his BSc from Delft University of Technology in the field of Mechanical Engineering. He specialized in Systems and Control, in which he obtained an MSc and a PhD.
During his doctoral studies, he developed and validated control methods to mitigate wake effects in large offshore wind farms to improve power production. One of these methods was patented, which triggered his interest to become a patent attorney. Mees joined V.O. Patents & Trademarks in 2025.

In G 1/25 (Enlarged Board of Appeal, 3 September 2026), the Enlarged Board of Appeal of the European Patent Office (EPO) decided whether, and on what legal basis, the description must be adapted when the claims are amended. The decision resolves a long-standing divergence in the case law of the Boards of Appeal and builds […]Continue reading
In UPC_CFI_523/2025, Wittenstein SE v Vestas Wind Systems A/S, the Court of First Instance, Central Division (Section Munich), decided on 2 September 2026 how lack of entitlement may operate as a ground for revocation under Article 138(1)(e) EPC. The Court held that it is not sufficient for a claimant to establish rights to only part […]Continue reading
In UPC_CoA_884/2025, Court of Appeal, 13 August 2026, the Unified Patent Court (UPC) considered when omission of a feature from an embodiment amounts to an unallowable intermediate generalisation. The decision clarifies the relationship between the general added-matter test, the concept of intermediate generalisation and the question whether an omitted feature is essential to the invention.Continue reading
