Company patents
Himax Technologies Limited
Himax Technologies Limited, while maintaining a strong focus on Display Drivers (23.7% of its portfolio), shows a surprising emerging emphasis on Computer Vision, with an 80.0% year-over-year growth in 2026 so far, despite a significant dip in 2025. Conversely, the company appears to be shifting priorities away from Speech Processing, which has seen a 100.0% decline in patent filings so far in 2026.
