The patent EP3221366 was granted to Plastipak Packaging on Jun 7, 2023. The application was originally filed on Nov 17, 2015 under application number EP15861861A. 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.
