1 case as defendant.
Maybell Quantum Industries Inc., often referred to as Maybell Quantum, is a privately held company headquartered in Denver, Colorado, with a European office and R&D hub in Copenhagen, Denmark. Founded in 2020 or 2021, the company focuses on quantum infrastructure. Maybell Quantum has approximately 70 to 100 employees and has raised a total funding of $112 million across multiple rounds, including a $25 million Series A in March 2024 and a Series B in September 2025.
Maybell Quantum specializes in manufacturing cryogenic infrastructure to support quantum computing and low-temperature research. Their primary products include dilution refrigerators, such as "The Fridge," "The Big Fridge," "Fast Fridge," and "Fridge+," which cool quantum devices to near-absolute zero temperatures (below 10 millikelvin). They also offer related components like coaxial and DC wiring solutions, magnets, and accessories. In March 2026, Maybell Quantum launched ColdCloud®, a patented cryogenic architecture designed for scalable, energy-efficient quantum datacenters, which decouples primary cooling from modular nodes. The company operates MayQ Labs, expert-managed quantum research facilities in Denver and Copenhagen.
Maybell Quantum appears to operate as an operating company, developing and selling its quantum infrastructure products. Their patent litigation posture reflects that of a company defending its intellectual property. The company has been involved in one tracked case as a defendant, Unified Patents LLC v. Maybell Quantum Industries Inc., which took place at the Patent Trial and Appeal Board (PTAB). This suggests that Maybell Quantum is being challenged on the validity of one of its patents, possibly by an entity focused on deterring non-practicing entity (NPE) assertions or challenging patent quality.
Notable context includes Maybell Quantum's focus on addressing the scalability and reliability challenges of quantum computing, as evidenced by their ColdCloud® platform and various dilution refrigerator systems. They have secured agreements, such as purchasing helium-3 from Interlune for future use in their dilution refrigerators, to support the anticipated scaling of quantum computing infrastructure.
An Inter Partes Review (IPR) was filed by Unified Patents LLC against Maybell Quantum Industries Inc., challenging US patent 12313320 before the Patent Trial and Appeal Board.
