Company patents

Pall Corporation

Pall Corporation's patent strategy reveals a surprising shift away from its core "Separation Processes (Filtration, Distillation)" category, which constitutes 70.0% of its portfolio but has seen a significant decline in new patents, with a -75.0% YoY drop so far in 2026. This suggests a broader de-emphasis across most categories, with "Heterocyclic Compounds (Pharma)" showing a brief surge of +300.0% YoY in 2024 before also declining, indicating a potential exploration into pharma that did not sustain.
