SUNCOKE TECHNOLOGY AND DEVELOPMENT LLC

SUNCOKE TECHNOLOGY AND DEVELOPMENT LLC's patent strategy reveals a surprising recent surge in materials-related innovation, with 72.8% of its portfolio (59 patents) concentrated in Powder Metallurgy, Alloys, and Water / Sewage Treatment, all of which saw significant patenting activity in 2025 after no patents in 2023-2024. However, so far in 2026, there's a notable decline across these key areas, with Powder Metallurgy down 64.3% YoY, Alloys down 50.0% YoY, and Water / Sewage Treatment down 37.5% YoY, suggesting a potential shift in focus or a completion of a specific R&D cycle.
