Patent No. EP3554248 (titled "A Beverage Product With Free Divalent Cations Protein Aggregation And A Method Producing Thereof") was filed by Nestle on Dec 18, 2017. The application was issued on Nov 6, 2024.
A method for producing a shelf-stable ready-to-drink beverage involves providing an ingredient composition of micellar caseins and whey protein (1.5–8 wt.%) with a casein-to-whey ratio of 90/10 to 60/40. The composition is supplemented with 3–20 mM free divalent cations (calcium from sources including chloride, lactate, gluconate, acetate, fumarate, malate, phosphate, or fractionated milk) and 0.025–0.3 wt.% high acyl gellan gum (50–99% acylation). The mixture undergoes ultra-high temperature (UHT) treatment at 135–150°C for 3–30 seconds, forming casein and beta-lactoglobulin agglomerates with a mean diameter D(4,3) of 5–30 microns. This process optimizes texture, mouthfeel, and physicochemical stability—preventing sedimentation, marbling, or gelation—while allowing for reduced fat and sugar content.

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.
