The patent EP4022252 was granted to Hexagon Metrology on Aug 30, 2023. The application was originally filed on Aug 31, 2020 under application number EP20767989A. 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.
