Company patents
Albemarle Corporation
Albemarle Corporation's patent strategy reveals a surprising, strong emerging focus on Batteries & Fuel Cells, which saw a remarkable 600.0% year-over-year growth in 2024, now accounting for 22.2% of its portfolio, mirroring its established strength in Catalysts & Reactors (also 22.2%). While many categories show no patent activity so far in 2026, the company appears to be shifting away from Petroleum / Hydrocarbon Refining, which saw a 100.0% decline in 2025.
