Company patents
NUOVO PIGNONE TECNOLOGIE - S.R.L.
Nuovo Pignone Tecnologie - S.r.l. demonstrates a strong focus on core aerospace technologies, with Steam / Gas Turbines (30.7% of portfolio) and Gas Turbine Plants (19.5% of portfolio) representing nearly half of its patent activity. While these core areas saw significant growth in 2024 (Steam / Gas Turbines +150.0%, Gas Turbine Plants +71.4%), it's surprising to note the rapid emergence of Separation Processes (Filtration, Distillation) as a key area, experiencing a remarkable 166.7% year-over-year growth in 2025, suggesting a diversification into materials processing, even as patenting activity across most categories has seen a sharp decline so far in 2026.
