The patent EP3781998 was granted to GD Societ PER Azioni on Oct 19, 2022. The application was originally filed on Apr 19, 2019 under application number EP19726155A. 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.
