Company patents
BL Technologies, Inc.
BL TECHNOLOGIES, INC. demonstrates a surprising shift in its patent strategy, moving away from its core focus areas like Water / Sewage Treatment (46.0% of portfolio) and Separation Processes (40.0% of portfolio), which saw significant declines of -41.7% and -66.7% respectively so far in 2026. This is further evidenced by the complete cessation of patenting in Petroleum / Hydrocarbon Refining and Functional Materials so far in 2026, despite a strong emerging focus in Material & Chemical Analysis with a 166.7% YoY growth in 2024, indicating a potential pivot towards analytical technologies rather than direct material processing.
