Company patents
Himax Technologies Limited
Himax Technologies Limited's patent strategy reveals a surprising shift away from its core "Display Drivers" (22.3% of portfolio) and "Input/Output & User Interfaces" (17.8% of portfolio) categories, both experiencing significant declines so far in 2026 (YoY -57.9% and -70.6% respectively), despite strong growth in 2024. While "Computer Vision" shows an emerging focus with a 40.0% YoY growth so far in 2026, the dramatic 300.0% YoY surge in "Radar / Sonar / Lidar" in 2025, followed by a sharp -75.0% decline so far in 2026, suggests a highly dynamic and potentially experimental approach to new sensing technologies.
