Company patents
SULZER MANAGEMENT AG
Sulzer Management AG's patent strategy shows a surprising diversification beyond its core manufacturing strengths, with a significant 19.3% of its portfolio in "Acyclic / Carbocyclic Compounds" (pharma_biotech), despite a declining trend in this area (YoY -14.3% in 2025). While "Pumps (Centrifugal)" remains its largest category at 31.9% of the portfolio, the rapid growth in "Electrolysis & Electrochemistry" (YoY +25.0% in 2025) and "Non-metallic Inorganic Compounds" (YoY -25.0% in 2025, but +100% in 2024) suggests an emerging focus on energy and advanced materials, even as patenting activity across most categories has seen a sharp decline so far in 2026.
