Company patents

PANTECH CORPORATION

PANTECH CORPORATION's patent strategy reveals a surprising and significant shift away from its historical dominance in Wireless Networks, which still comprises 88.7% of its portfolio but has seen a sharp decline in new filings, with a -83.3% YoY drop so far in 2026. This decline is mirrored across most categories, including a complete cessation of new patents in Physical Transmission & Modulation, Multiplex Communication, and Messaging & Email, indicating a broad de-prioritization of core communication technologies.
