Compositions

Patent No. EP2640893 (titled "Compositions") was filed by Fiberlean on Nov 9, 2011. The application was issued on Feb 24, 2021.

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.
