Company patents

Furuno Electric Co., Ltd.

FURUNO ELECTRIC CO., LTD. demonstrates a dynamic patent strategy, with a surprising emerging focus on "Traffic Control Systems," which saw a remarkable 160.0% year-over-year growth in 2025, now representing 12.7% of its portfolio. While core areas like "Radar / Sonar / Lidar" (37.1% of portfolio) and "Ships & Marine Vessels" (27.3%) remain significant, the sharp decline in "Material & Chemical Analysis" patents, with a -100.0% YoY drop so far in 2026, suggests a shifting priority away from this area.
