Company patents
ArcelorMittal
ArcelorMittal's patent strategy shows a surprising volatility in its core "Alloys" category, which, despite comprising 53.3% of its portfolio, experienced a dramatic 92.9% growth in 2025 after a 28.2% decline in 2024, followed by a sharp 64.8% drop so far in 2026. While its traditional materials and manufacturing areas like "Welding & Soldering" are consistently declining (e.g., -27.8% in 2025), the company is showing an emerging focus on "Powder Metallurgy," which saw a remarkable 300.0% growth so far in 2026, indicating a potential shift towards advanced material processing.
