Company patents
WANGS ALLIANCE CORPORATION
WANGS ALLIANCE CORPORATION's patent strategy reveals a surprising, sharp decline in its core consumer lighting technologies, with Lighting Devices (Functional Features) dropping by 63.0% in 2025 and Electric Heating & Lighting Control by 62.9% in 2025, after significant growth in 2024. This suggests a rapid shift away from these previously dominant areas, which together represent over 90% of its portfolio, while manufacturing categories like Grinding & Polishing and Pumps (Centrifugal) saw a complete cessation of patenting in 2025 after explosive growth in 2024.
