Signify China Investment Co Ltd is the Chinese operational arm of Signify N.V., a Dutch multinational lighting corporation. Signify N.V., formerly known as Philips Lighting N.V., was formed in 2016 following a spin-off from Royal Philips, with its roots in Philips' original lighting division established in 1891. Headquartered in Eindhoven, Netherlands, Signify N.V. is publicly traded on the Euronext Amsterdam exchange under the ticker LIGHT. As of the end of 2025, Signify N.V. reported approximately 26,629 employees and annual sales of EUR 5.765 billion.

Signify is a global leader in lighting solutions for professionals, consumers, and the Internet of Things (IoT). The company manufactures and sells a wide range of energy-efficient lighting products, systems, and services, including LED lamps, light fixtures, and control systems. Its major brands include Philips (under license), Philips Hue, Color Kinetics, and WiZ. Signify's offerings cater to various market segments, such as smart buildings, smart cities, offices, retail, hospitality, industry, agriculture, and homes, with an increasing focus on connected lighting systems and data-enabled services like Lighting-as-a-Service and Interact IoT platforms. China is a significant market for Signify, housing eight of its factories and serving as an innovation hub for technologies that are often developed locally before being rolled out globally.
Signify China Investment Co Ltd's patent litigation posture indicates it operates as a defendant in patent infringement suits rather than an asserting entity. The company has been tracked in one case as a defendant and zero as a plaintiff. This single case was filed in the Eastern District of Texas, a venue recognized for its plaintiff-friendly characteristics in patent litigation.
The sole tracked case involving Signify China Investment Co Ltd is Stingray IP Solutions LLC v. Signify Netherlands BV et al., filed on February 8, 2021. The inclusion of "et al." in the case name suggests that Signify China Investment Co Ltd was likely named as a co-defendant alongside its parent company, Signify Netherlands BV, in this patent dispute.
