Company patents
HOYA LENS THAILAND LTD.
HOYA LENS THAILAND LTD's patent strategy is heavily concentrated in Optical Elements & Systems, representing 37.6% of its portfolio, yet this core area has seen a significant decline in recent filings, with a -32.3% YoY drop in 2025 and a further -66.7% so far in 2026. Surprisingly, while many categories show a slowdown in 2026, the company saw a remarkable 700.0% YoY growth in Coating Compositions (Paints, Inks) in 2024, indicating a past emerging focus on material science applications, though this also declined in 2025 and 2026.
