I'll research this company to verify its profile.
Marmon Foodservice Technologies, Inc. — commonly shortened to Marmon Foodservice Technologies (MFT) — is a US commercial foodservice-equipment manufacturer headquartered at 355 Kehoe Blvd., Carol Stream, Illinois (some business databases also list a Plymouth, Minnesota office). It is a subsidiary of Marmon Holdings, Inc., which since 2008 has been wholly owned by Berkshire Hathaway Inc.; it is not publicly traded. The MFT entity was assembled around 2019 from Marmon's foodservice businesses, though its brands date to the 1920s–1930s. Standalone headcount and revenue for MFT are not publicly disclosed; parent Marmon reports roughly $12 billion in annual revenue and 30,000+ employees across 120-plus businesses.
Products / operations. MFT manufactures and services commercial food and beverage equipment for restaurants, convenience stores, hotels, and institutional kitchens. Its brand portfolio includes Cornelius (fountain, frozen-carbonated, juice and ice beverage dispensing; product lines such as Viper, IDC Pro, Enduro, Quest and ACSD), Prince Castle (holding bins, batch toasters, timers, Saber King slicers), Silver King (commercial refrigeration and dairy dispensers), Angelo Po (professional cooking/combustion and combi ovens), Display Technologies (beverage merchandising glides/displays), plus Marmon Link (parts distribution and technical support) and Marmon Renew (beverage-equipment remanufacturing). U.S. manufacturing/support sites include Carol Stream, Illinois; Osseo, Minnesota; Monmouth, Illinois; and Reynosa, Mexico.
Patent-litigation posture. MFT is an operating company and a one-way plaintiff in the tracked data: 2 cases as plaintiff, 0 as defendant. Both tracked suits are patent-infringement actions against Duke Manufacturing Co., filed in the U.S. District Court for the Eastern District of Missouri (Eastern Division, Case No. 4:25-cv-01491, filed September 3, 2025). This is not an NPE fact pattern — MFT sells the accused technology and marks its products with patents under 35 U.S.C. § 287(a).
Context. The dispute is between two St. Louis-area commercial foodservice-equipment makers and has become two-way at the USPTO: Duke has filed inter partes review petitions challenging MFT patents (e.g., IPR2026-00406 and IPR2026-00479). The venue reflects the parties' Midwest operations rather than a plaintiff-friendly NPE forum.
