The patent EP4069522 was granted to Leonhard Kurz Stiftung on Dec 4, 2024. The application was filed on Nov 20, 2020 under application number EP20811302A. 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.
