Company patents
ANRITSU CORPORATION
ANRITSU CORPORATION's patent strategy reveals a surprising shift, with a strong focus on Wireless Networks (20.3% of portfolio) and Electrical Measurement (16.5%), yet both show significant declines in 2026 so far (Wireless Networks -8.3%, Electrical Measurement -84.6%). Despite this, the company demonstrated an emerging focus in Material & Chemical Analysis and Physical Transmission & Modulation, which saw remarkable year-over-year growth of +200.0% and +300.0% respectively in 2025, suggesting a dynamic and re-prioritized R&D landscape.
