The patent EP2978833 was granted to Rhodia Operations on Feb 17, 2021. The application was originally filed on Mar 25, 2014 under application number EP14712299A. The patent is currently recorded with a legal status of "Opposition Rejected".

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.
