Company patents
Kubota Corporation
Kubota Corporation's patent strategy reveals a surprising and aggressive pivot towards Electric Vehicle Propulsion, with a remarkable 400.0% YoY growth in 2024 and an 81.8% YoY growth in 2025, now representing 12.7% of its portfolio, alongside a significant emerging focus on Batteries & Fuel Cells (600.0% YoY growth in 2025). While traditionally strong areas like Excavating & Earth-Moving (22.6% of portfolio) and Vehicle Powertrain Arrangement (21.9% of portfolio) saw substantial growth in 2025, the sharp decline in patent filings across most categories so far in 2026 suggests a potential re-evaluation or shift in R&D focus, with the exception of Computer Vision which continues to grow at 45.5% YoY in 2026.
