The patent EP3999211 was granted to Mercedes Benz Group on Sep 20, 2023. The application was originally filed on Apr 16, 2021 under application number EP21720705A. 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.
