Hill Phoenix, Inc. (styled "Hillphoenix") is a U.S. commercial refrigeration manufacturer headquartered at 2016 Gees Mill Road, Conyers, Georgia. It is a wholly owned subsidiary of Dover Corporation (NYSE: DOV), which acquired the business in 1993; Dover is headquartered in Downers Grove, Illinois, with annual revenue exceeding $7 billion. Hillphoenix operates within Dover's Food Retail segment alongside the Anthony, Advansor, and AMS Group brands. Dover Food Retail reports more than 3,000 employees worldwide; third-party employment databases list the Hillphoenix brand at roughly 1,000–5,000 employees, and Dover does not break out Hillphoenix-specific revenue. The company's origins are commonly dated to 1887, though this is drawn from business databases rather than a definitive corporate source.
Products and operations. Hillphoenix designs and manufactures commercial refrigerated display merchandisers and display cases, commercial and light-industrial refrigeration systems, mechanical centers, integrated electrical power distribution systems, and walk-in coolers and freezers. Its customers are primarily supermarkets, convenience stores, and other food retail and food-service operators. It maintains U.S. manufacturing sites, including a large facility on Ruffin Mill Road in South Chesterfield, Virginia, opened in 1995, which Dover announced in late 2025 it would expand by about $20 million to relocate Anthony-brand production from Los Angeles. The company markets itself on environmentally sustainable refrigeration technology, including low-GWP and natural-refrigerant systems, and has received EPA GreenChill recognition.
Patent-litigation posture. Hillphoenix is an operating company and, in the tracked data, appears solely as a defendant (0 plaintiff cases, 1 defendant case). It is not a patent enforcer or an NPE; the single tracked suit is a defensive matter.
Notable case. ControlTec, LLC v. Anthony, Inc. et al., No. 1:24-cv-00883 (D. Del., filed July 26, 2024), names Hillphoenix and fellow Dover subsidiary Anthony, Inc. as co-defendants. Plaintiff ControlTec asserted U.S. Patent Nos. 7,207,181 and 7,421,847, directed to anti-sweat heater/condensation control in refrigerated display cases, targeting Anthony "Energy Controller" products. Hillphoenix's Rule 7.1 disclosure identifies Dover Corporation and The Vanguard Group. ControlTec's own disclosure states no parents or affiliates; Unified Patents' PTAB records list the petitions (IPR2025-00559 and IPR2025-00636) as operating-company-filed challenges, and both patents have expired.
