Company patents
UCHICAGO ARGONNE, LLC
UCHICAGO ARGONNE, LLC's patent strategy reveals a strong, but surprisingly declining, focus on Batteries & Fuel Cells, which constitutes 39.5% of its portfolio but saw a significant 18.6% drop in 2025 and a further 48.6% decline so far in 2026. While many materials-related categories are also experiencing declines, the fluctuating activity in Acyclic / Carbocyclic Compounds, with a 100.0% growth so far in 2026 after a sharp drop in 2024, suggests a potential, albeit nascent, re-evaluation of its pharma_biotech-related priorities.
