Company patents
Darfon Electronics Corp.
DARFON ELECTRONICS CORP. surprisingly shows a strong, albeit fluctuating, commitment to Optical Elements & Systems, which grew by +56.2% in 2024, despite its primary focus remaining on Switches, representing 72.3% of its portfolio. While patenting in core areas like Switches and Optical Elements & Systems has seen declines in 2025 and so far in 2026, the significant drop in Pulse / Digital Logic Circuits (YoY -66.7% in 2025 and -100.0% so far in 2026) suggests a notable shift away from this semiconductor sub-domain.
