The patent EP3601383 was granted to Basell Poliolefine Italia on Apr 10, 2024. The application was originally filed on Mar 23, 2018 under application number EP18711593A. 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.
