Company patents
Solvay SA
Solvay SA's patent strategy shows a surprising shift, with its dominant category, Batteries & Fuel Cells (36.8% of portfolio), experiencing a sharp decline in filings, dropping by 60.0% in 2024 and 100.0% in 2025. While several categories like Polymer Additives (+300.0% YoY in 2024) and Catalysts & Reactors (+200.0% YoY in 2024) showed rapid growth, the overall trend indicates a significant reduction in patenting activity across most areas in 2025 and so far in 2026, with only one patent filed in Compounds Containing Metals in 2026.
