The patent EP2851526 was granted to Emcon Germany Augsburg on May 23, 2018. The application was originally filed on Aug 11, 2004 under application number EP14190957A. 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.
