The patent EP2858958 was granted to Morgan Advanced Materials on Jun 12, 2019. The application was originally filed on Jun 23, 2014 under application number EP14732627A. The patent is currently recorded with a legal status of "Opposition Rejected".

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.
