Optimized Fc Variants

Patent No. EP2471813 (titled "Optimized Fc Variants") was filed by Xencor on May 5, 2005. The application was issued on Dec 31, 2014.

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.
