Patent No. EP2464679 (titled "Improved Nylon Resins And Process") was filed by Invista on Aug 6, 2010. The application was issued on Apr 4, 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.
