Company patents

TDK TAIWAN CORP.

TDK TAIWAN CORP's patent strategy is heavily concentrated in "Optical Elements & Systems," which accounts for 84.0% of its portfolio, yet patenting in this core area has seen a significant decline of 84.6% so far in 2026. Surprisingly, while many categories show a sharp drop in 2026, the company had an emerging focus in "Magnets & Inductors," which grew by 90.0% in 2025, and "Inorganic Devices (Thermoelectric, Piezo)," which grew by 44.4% in 2025, indicating a potential shift towards these specialized electronic components despite the overall slowdown in patenting activity so far in 2026.
