The patent EP3488755 was granted to Carl Freudenberg on Jan 26, 2022. The application was originally filed on Nov 24, 2017 under application number EP17203440A. 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.
NPL citations refer to non-patent references such as research papers, articles, or other publications cited during examination or opposition phases.
