Chromate Free Pretreatment Primer

Patent No. EP3140356 (titled "Chromate Free Pretreatment Primer") was filed by PRC Desoto on May 7, 2015. The application was issued on Sep 18, 2024.

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.
