Company patents
PROTERIAL, LTD.
PROTERIAL, LTD. demonstrates a dynamic patent strategy, with a strong foundational focus on "Alloys" (21.5% of portfolio) and "Cables & Conductors" (19.2%), yet surprisingly, both categories show significant declines so far in 2026 (YoY -53.1% and -61.3% respectively). While many categories experienced rapid growth in 2024, such as "Additive Manufacturing (3D Printing)" (+250.0% YoY) and "Material & Chemical Analysis" (+350.0% YoY), the company appears to be shifting priorities, as evidenced by the sharp decline in patenting activity across most categories in 2026, with the exception of "Measurement (Non-specific)" which saw a remarkable +125.0% YoY growth in 2026, indicating an emerging focus despite the overall portfolio's current year's partial data.
