Company patents
Bridgelux, Inc.
Bridgelux, Inc. demonstrates a shifting patent strategy, with a strong historical focus on "Multi-Chip & 3D Assemblies" (57.6% of its portfolio) and "LED & Optoelectronics (Legacy CPC)" (49.2%), which saw a significant 142.9% YoY growth in 2024 but has since declined sharply. While many categories show a decline in 2026 so far, the emergence of "Light-Emitting Devices (LEDs)" with 11 patents in 2025 (from zero in prior years) suggests a potential new area of focus, despite a -63.6% YoY drop in 2026, which is based on partial year data.
