The patent EP3374552 was granted to Michel VAN DE Wiele on Aug 4, 2021. The application was filed on Nov 10, 2016 under application number EP16816383A. 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.
