Company patents
ADVANTEST CORPORATION
ADVANTEST CORPORATION's patent strategy is heavily concentrated in Electrical Measurement, representing 62.4% of its portfolio, yet this core area has seen a significant decline of 67.7% so far in 2026. Surprisingly, while many smaller categories like System Reliability & Diagnostics and Computer Hardware Architecture showed rapid growth in 2024 (350.0% and 200.0% YoY respectively), their patenting activity has sharply decreased or ceased in 2026, indicating a potential shift away from these previously emerging focuses.
