Company patents

ADVANCED SEMICONDUCTOR ENGINEERING, INC.

ADVANCED SEMICONDUCTOR ENGINEERING, INC. exhibits a concentrated patent strategy in core semiconductor areas like Semiconductor Packaging & Encapsulation (60.5% of portfolio) and Chip-to-Chip Interconnect (36.2%), yet surprisingly shows a consistent decline in patenting activity across most major categories over the past two years, with Semiconductor Manufacturing Process seeing a significant -33.3% YoY drop in 2025. Despite this, there's an emerging focus in Medical Diagnostics & Surgery, which grew by +33.3% YoY in 2025, suggesting a diversification into adjacent high-growth sectors, while patenting in LED & Optoelectronics and Photovoltaic Cells has ceased entirely so far in 2026.
