The Serine Protease Inhibitors (Serpins) have been a focus of research by biomedical industries due to their
critical role in human health. The use of serpin in the treatment of many diseases was widely investigated through the
identification of new genes encoding these proteins in all kingdoms of life. The characterization of these genes revealed
that they encoded proteins having low sequence homologies. Future developments are focusing not only on the protease
inhibition activity, but also on the other effects due to the interactions of serpins with other components such as hormone
transport. Here we give a concise overview of the most recent patents that have been reported in this field of research.
Keywords: Serpin, biotechnological applications, health, blood clotting, cancer, anti-viral, inflammation.
