The patent EP3226727 was granted to Eugsterfrismag on Feb 13, 2019. The application was originally filed on Dec 1, 2015 under application number EP15802142A. 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.
