The patent EP2754440 was granted to Mitsubishi Tanabe Pharma on Apr 3, 2019. The application was originally filed on Sep 5, 2012 under application number EP12830484A. The patent is currently recorded with a legal status of "Revoked".

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.
