Company patents
ALSTOM Holdings
ALSTOM Holdings' patent strategy reveals a surprising lack of sustained focus across many categories, with significant year-over-year declines in several areas. For instance, despite a recent peak, patents in Electric Motors & Generators, representing 8.1% of their portfolio, show a -50.0% YoY decline so far in 2026, and categories like Traffic Control Systems and Alarm & Signaling Systems have seen a -100.0% YoY decline in 2026, indicating a shifting priority away from these areas.
