Patent No. EP4346444 (titled "Lactation Stage Specific Infant Nutrition") was filed by Nutricia on Jun 2, 2022. The application was issued on Aug 27, 2025.
An age-specific infant formula for infants aged 0 to 4 months is disclosed, designed to mimic human milk composition to support gut and immune system maturation. The formula comprises 0.05–0.30 g/l 3'-sialyllactose (3'-SL) (preferably 0.08–0.25 g/l, more preferably 0.10–0.20 g/l, and even more preferably 0.10–0.18 g/l), 0.3–1 g/l 3-fucosyllactose (3-FL) (preferably 0.4–0.9 g/l, more preferably 0.5–0.8 g/l), and difucosyllactose (DFL). The 3'-SL and DFL are present in a weight ratio between 1:1.1 and 1:2. The composition may further include 2'-fucosyllactose (2'-FL), fructo-oligosaccharides (average DP >20), and galacto-oligosaccharides (average DP 3–7). The formula may be provided in liquid or powder form and may be adapted for infants

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.
