SAFRAN HELICOPTER ENGINES
SAFRAN HELICOPTER ENGINES demonstrates a strong, albeit fluctuating, commitment to core aerospace technologies, with Gas Turbine Plants (36.8% of portfolio) and Aircraft Equipment (35.3% of portfolio) dominating its patent strategy. While Powder Metallurgy shows consistent growth, increasing by 66.7% in 2025, the significant year-over-year declines across most categories so far in 2026, such as Gas Turbine Plants (-73.1%) and Aircraft Equipment (-66.7%), suggest a potential shift in focus or a natural slowdown after a period of high activity in 2024.
