The patent EP2245096 was granted to Rolls Royce on Aug 1, 2018. The application was originally filed on Jan 13, 2009 under application number EP09702198A. 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.
