The patent EP1660022 was granted to HFC Prestige Holding Switzerland on Apr 12, 2017. The application was originally filed on Jul 6, 2004 under application number EP04763105A. 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.
Patent citations refer to prior patents cited during different phases such as opposition or international search.
