The patent EP3773399 was granted to The Procter & Gamble on Jan 17, 2024. The application was originally filed on Mar 26, 2019 under application number EP19716269A. 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.
