Polyethylene Compositions

Patent No. EP2300529 (titled "Polyethylene Compositions") was filed by Univation on Jul 7, 2009. The application was issued on May 3, 2017.

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.
