Patent No. EP3666079 (titled "Concentrated Natural Food Additive And Methods Of Preparing The Same") was filed by WTI on Jun 8, 2016. The application was issued on Jul 30, 2025.
A method for preparing a concentrated, powder-form food additive consists of treating vinegar with a basic neutralizing agent—such as sodium, potassium, calcium, or magnesium bicarbonates or carbonates—to partially neutralize the vinegar to a pH range of 4.0 to 5.5. The resulting product is then dried via water evaporation, using processes such as spray drying or vacuum drying, to produce a concentrated additive consisting of an acetate (e.g., sodium, potassium, calcium, or magnesium acetate) and an acid. This naturally derived additive serves as a buffer for pH control, a water-binding agent, or an antimicrobial agent to increase the shelf-life of meat products, including beef, pork, poultry, and fish.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
The dossier documents provide a comprehensive record of the patent's prosecution history - including filings, correspondence, and decisions made by patent offices - and are crucial for understanding the patent's legal journey and any challenges it may have faced during examination.
