Anthony, Inc. (commonly "Anthony" or "Anthony International") is a manufacturer of commercial refrigeration glass doors and merchandising systems, headquartered at 12391 Montero Avenue, Sylmar, California. Founded in 1958 by Gerald Anthony Linglebach and Michael Stromquist, the company was acquired by Dover Corporation (NYSE: DOV) for $602.5 million in November 2012 from private-equity owner Avista Capital Partners and operates within Dover's Refrigeration & Food Equipment segment. Anthony is a private operating subsidiary of the publicly traded Dover; Dover's 2012 acquisition release estimated Anthony's revenue at roughly $310 million for that year (third-party databases suggest a 1,000–5,000 employee headcount, though this is not independently confirmed).
Products / operations. Anthony designs and manufactures glass refrigerator and freezer doors, case lighting systems, shelving, beer-cave and sliding doors, viewing windows, curved/specialty glass, and "re-skinning"/retrofit services for commercial refrigeration display cases used by supermarkets and convenience stores. The company also produces its own electronic controls — including the "Anthony Energy Controller" anti-sweat control units that are the accused products in its tracked litigation — and holds its own patents (e.g., U.S. 8,250,873 on an anti-condensation control system).
Patent-litigation posture. Anthony is an operating company in a two-way dispute with ControlTec, LLC. Per the case data, Anthony is defendant in one suit — ControlTec, LLC v. Anthony, Inc., No. 1:24-cv-00883 (D. Del., filed July 2024), where ControlTec alleged infringement of U.S. Patents 7,207,181 and 7,421,847 ("Refrigeration Unit Condensation Prevention") — and plaintiff in one PTAB proceeding (Anthony, Inc. v. ControlTec, LLC, IPR2025-00559/00636), the inter partes reviews Anthony filed against those same patents. The district-court venue is Delaware, not a plaintiff-friendly forum like the Eastern District of Texas.
Notable context. The Delaware suit, which also names Dover-affiliated co-defendant Hill Phoenix, Inc., targets Anthony's Energy Controllers used in its 101, 401, Infinity, and Vista C door lines. The PTAB instituted Anthony's IPR petitions in 2025 despite the patents having expired, citing a material examiner error; the proceedings were still pending as of the case data date. ControlTec appears to be a patent-holding entity (it reported no parent or affiliates in its Rule 7.1 disclosure), while Anthony is the product-making company defending itself.
