The patent EP2430878 was granted to Zimmerer on Jul 20, 2022. The application was filed on May 4, 2010 under application number EP10722586A. 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.
