Company patents
Stora Enso OYJ
Stora Enso OYJ's patent strategy reveals a surprising volatility in its core materials and consumer packaging innovations, with significant year-over-year fluctuations. For instance, while Layered Products (Laminates, Films) saw a dramatic 127.3% increase in 2025, it experienced an 80.0% decline so far in 2026, indicating a dynamic but inconsistent focus across its largest category (26.2% of its portfolio).
