The patent EP3737234 was granted to Jafer Enterprises R&D SL on Aug 14, 2024. The application was originally filed on Jan 8, 2019 under application number EP19700261A. The patent is currently recorded with a legal status of "Granted And Under Opposition".

Patent citations refer to prior patents cited during different phases such as opposition or international search.
