Company patents

PREFORMED LINE PRODUCTS CO.

PREFORMED LINE PRODUCTS CO. surprisingly shows a significant patent focus in 'Power Cable Installation', accounting for 48.1% of its portfolio, despite a notable decline of 60.0% in patents so far in 2026 compared to 2025. While 'Aircraft & Aerodynamics' and 'Unmanned Aerial Vehicles (Drones)' saw rapid growth of 200.0% in 2025, their complete absence of patents so far in 2026 suggests a potential shift in priorities away from these aerospace-related areas.
