Company patents
Au Optronics Corporation
Au Optronics Corporation's patent strategy shows a surprising and significant decline across nearly all categories, with major areas like Integrated Circuit Layout & Arrangement (25.2% of portfolio) and LED & Optoelectronics (Legacy CPC) (22.5% of portfolio) experiencing drastic year-over-year drops of -58.3% and -39.3% respectively in 2024, and further steep declines into 2025 and 2026 (so far). The only notable recent activity is in Light-Emitting Devices (LEDs), which saw 9 patents in 2025, suggesting a potential, albeit small, shift in focus amidst a broader portfolio contraction.
