Patent No. EP3445809 (titled "Polymerizable Composition") was filed by Lanxess Deutschland on Mar 29, 2017. The application was issued on Jan 22, 2020.

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.
