Nutrient Composition

Patent No. EP2374452 (titled "Nutrient Composition") was filed by Ajinomoto on Dec 4, 2009. The application was issued on Jul 24, 2019.

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.
