The patent EP3727599 was granted to Laboratoire Biosthetique Kosmetik on Nov 22, 2023. The application was originally filed on Dec 21, 2017 under application number EP17851830A. 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.
