The patent EP3356579 was granted to Coventya on Mar 11, 2020. The application was originally filed on Sep 30, 2016 under application number EP16778284A. The patent is currently recorded with a legal status of "Revoked".

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.
