The patent EP2575847 was granted to F Hoffmann LA Roche on Apr 27, 2022. The application was originally filed on May 25, 2011 under application number EP11787363A. 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.
