Company patents
Hubbell Incorporated
Hubbell Incorporated's patent strategy reveals a surprising shift away from its core Electrical Connectors (26.2% of portfolio) and Power Cable Installation (23.5% of portfolio) categories, both experiencing significant declines in 2026 so far (YoY -45.7% and -46.0% respectively). Despite a strong surge in Pipes & Tubing in 2024 (YoY +500.0%) and Printed Circuits & Electronic Assemblies in 2025 (YoY +50.0%), the overall trend across most categories in 2026 indicates a broad reduction in patenting activity.
