The patent EP3570680 was granted to Rousselot on Jun 18, 2025. The application was originally filed on Jan 19, 2018 under application number EP18700508A. The patent is currently recorded with a legal status of "Patent Maintained As Amended".

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.
Patent citations refer to prior patents cited during different phases such as opposition or international search.
NPL citations refer to non-patent references such as research papers, articles, or other publications cited during examination or opposition phases.
