The patent EP1861462 was granted to Akzo Nobel on Sep 5, 2018. The application was originally filed on Mar 13, 2006 under application number EP06723383A. 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.
NPL citations refer to non-patent references such as research papers, articles, or other publications cited during examination or opposition phases.
