Radiant Patents LLC is a US-based technology company that manages and licenses patents related to fiber optic communications and networks. The company's principal address is in New York, New York. Public records indicate the company was formerly known as PLS XLIV LLC. Radiant Patents is a private entity, and no information regarding its employee count or revenue is publicly available.
As a non-practicing entity (NPE), Radiant Patents does not manufacture products or provide services. Instead, its operations focus on licensing a portfolio of approximately 120 global patents originally developed by The Nippon Electric Company (NEC). This portfolio covers technologies for high-speed data transmission over long distances, which are fundamental to modern telecommunications and the internet. The patents relate to technologies such as optical transmission systems, digital coherent optics, and multilevel modulation.
The company's patent-litigation posture is that of a patent assertion entity. All of its tracked cases are as a plaintiff, and it has no recorded cases as a defendant. This pattern is characteristic of an NPE focused on asserting its patent portfolio. The lawsuits initiated by Radiant Patents have been filed in the U.S. District Court for the Eastern District of Texas, a venue known for being plaintiff-friendly in patent disputes.
In January 2026, Radiant Patents filed two lawsuits against Nokia Corporation in the Eastern District of Texas. These cases involve allegations of infringement of patents related to optical networking technologies. Specifically, the asserted patents include U.S. Patent 10,623,095, which relates to a signal detection device for WDM optical communication systems, and U.S. Patent 11,431,431, concerning an optical wavelength-path communication node. According to Unified Patents, Radiant Patents is an entity of MVRE LLC.
