Process For Preparing Polyurea Microcapsules

Patent No. EP2579976 (titled "Process For Preparing Polyurea Microcapsules") was filed by Firmenich on Jun 7, 2011. The application was issued on Aug 9, 2017.

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.
