Company patents
PANTECH CORPORATION
PANTECH CORPORATION's patent strategy reveals a surprising and significant decline across nearly all categories, with its dominant 'Wireless Networks' portfolio (88.2% of total patents) experiencing a -36.8% YoY drop in 2024 and a further -83.3% so far in 2026, suggesting a substantial shift away from core communications technology development. This is further emphasized by the complete cessation of patenting in 'Physical Transmission & Modulation' and 'Telephone Equipment' so far in 2026, indicating a broad de-prioritization of traditional communication hardware and infrastructure.
