Company patents
Neste Oyj
Neste Oyj, despite its core focus on Petroleum / Hydrocarbon Refining (69.9% of its portfolio), shows a surprising and rapid emerging focus in Catalysts & Reactors, which grew by an impressive 160.0% in 2025. While patenting in its primary category saw a significant increase of 34.4% in 2025, the company also demonstrates a shifting priority in Acyclic / Carbocyclic Compounds, experiencing a 54.5% decline in 2025, and a notable increase in Separation Processes (Filtration, Distillation) so far in 2026 with a 66.7% growth.
