Patent No. EP2999751 (titled "Anti-Corrosive Particles") was filed by Grace on Dec 8, 2009. The application was issued on Jun 27, 2018.

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.
