Warewashing Method

Patent No. EP3282004 (titled "Warewashing Method") was filed by Ecolab USA on May 18, 2012. The application was issued on Mar 26, 2025.

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.
