Compositions For Prevention Of Adhesions And Other Barrier Applications

Patent No. EP2581097 (titled "Compositions For Prevention Of Adhesions And Other Barrier Applications") was filed by Arch Biosurgery on Apr 25, 2008. The application was issued on Jun 7, 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.
