Composition containing alpha 1-proteinase inhibitor (API) and one or more amino acids for stabilizing API-containing pharmaceuticals.

This stabilized API composition can be useful for treating disorders associated with low API levels like COPD, liver disease, and vascular disorders.

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.
