The patent EP2946089 was granted to Safran Aircraft Engines on May 3, 2023. The application was originally filed on Jan 9, 2014 under application number EP14703117A. 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.
The dossier documents provide a comprehensive record of the patent's prosecution history - including filings, correspondence, and decisions made by patent offices - and are crucial for understanding the patent's legal journey and any challenges it may have faced during examination.
