OSHKOSH DEFENSE, LLC

OSHOSH DEFENSE, LLC's patent strategy reveals a surprising, strong emerging focus on Electric Vehicle Propulsion, with an 83.3% YoY growth in 2024, indicating a significant shift towards electrification despite its traditional defense vehicle manufacturing. While core areas like Vehicle Powertrain Arrangement (49.5% of portfolio) remain dominant, the sharp decline in filings across most categories so far in 2026, including a 100% drop in Vehicle Brake Systems and Gearing & Transmissions, suggests a potential re-evaluation or strategic pause in patenting efforts for these areas.
