The patent EP3536712 was granted to Regeneron Pharmaceuticals on May 31, 2023. The application was originally filed on Sep 12, 2012 under application number EP19162319A. The patent is currently recorded with a legal status of "Granted And Under Opposition".

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.
