Hillphoenix, Inc. (commonly styled "Hillphoenix" or legacy "Hill PHOENIX") is a US manufacturer of commercial refrigeration equipment headquartered at 2016 Gees Mill Road, Conyers, Georgia. It is a wholly owned operating company of Dover Food Retail, itself a segment of Dover Corporation (NYSE: DOV); Vanguard Group is also identified as a parent/affiliate in court filings. Business directories date the business to 1887, tracing to Hill Refrigeration, and Hillphoenix today is the senior brand within a group that includes Anthony, Advansor and The AMS Group. Public sources put the broader Dover Food Retail business at more than 3,000 employees; Dover itself reported roughly $7.75 billion in 2024 revenue with about 24,000 employees.
Hillphoenix designs and manufactures commercial refrigerated display cases, walk-in coolers and freezers, glass and freezer doors, and commercial and industrial refrigeration systems, including CO2/transcritical (Advansor) platforms and integrated power-distribution systems, sold mainly to supermarkets, convenience stores and food-service operators. It also provides training and aftermarket services through the Hillphoenix Learning Center and The AMS Group. It is an operating company, not a patent-assertion entity.
Litigation posture: the single tracked matter, Anthony, Inc. et al. v. ControlTec, LLC, is a USPTO Patent Trial and Appeal Board proceeding (IPR2025-00559 and IPR2025-00636, petitions filed January–February 2025) in which Anthony, Inc. is petitioner and Hillphoenix is a named real party-in-interest. Hillphoenix therefore appears on the challenger side of IPRs defending itself against an outside patent owner — consistent with the data's "1 plaintiff case / 0 defendant cases." The underlying infringement suit, ControlTec, LLC v. Anthony, Inc., No. 1:24-cv-00883 (D. Del.), names Hillphoenix as a co-defendant; the venue is Delaware, not the Eastern District of Texas.
Case context: ControlTec, a Delaware entity, asserted U.S. Patent Nos. 7,207,181 and 7,421,847 ("Refrigeration Unit Condensation Prevention"), covering frame and door heaters that prevent condensation on refrigerated display cases. Both patents expired in July 2025, and Acting USPTO Director Coke Morgan Stewart declined discretionary denial, referring the petitions to the Board based on an asserted material examination error.
