Company patents
JOHNSON ELECTRIC INTERNATIONAL AG
JOHNSON ELECTRIC INTERNATIONAL AG's patent strategy reveals a surprising shift towards Valves, which now constitute 34.1% of its portfolio and saw a significant 400.0% YoY growth in 2024, followed by a 40.0% growth in 2025, indicating an emerging focus despite a partial decline so far in 2026. This contrasts with a notable decline in Electric Motors & Generators, which, despite being a core area at 27.3% of the portfolio, experienced a 66.7% YoY drop in 2024 and a 100.0% decline so far in 2026, suggesting a shifting priority away from this traditional strength.
