The patent EP3604532 was granted to Massachusetts Institute OF Technology on May 1, 2024. The application was filed on Jun 17, 2016 under application number EP19171732A. 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.
