The patent EP2661492 was granted to The Johns Hopkins University on Oct 4, 2017. The application was originally filed on Jan 6, 2012 under application number EP12731900A. The patent is currently recorded with a legal status of "Revoked".

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.
