Company patents

LARGAN DIGITAL CO., LTD.

LARGAN DIGITAL CO., LTD. maintains a strong focus on "Optical Elements & Systems," representing 93.9% of its portfolio, despite a consistent decline in patenting activity in this core area, with a -24.0% YoY drop in 2025. Surprisingly, while most categories show significant declines so far in 2026, the company saw a notable increase in "Photographic Apparatus" patents in 2025 (YoY +27.3%) and a rapid emergence in "Pictorial / Video Communications" with a +42.9% YoY growth in 2025, suggesting a shifting priority towards integrated imaging and communication solutions, though 2026 data is partial and shows a sharp decrease across the board.
