The patent EP3536807 was granted to The Chinese University OF Hong Kong on Nov 29, 2023. The application was originally filed on Sep 20, 2013 under application number EP19171630A. 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.
