LACEY, Wash. -- Unigen Pharmaceuticals, Inc., a leading research and development company of proprietary, biologically active plant-derived ingredients has received notification of approval of a USA patent for Free-B-Ring Flavonoids derived from Chinese Skullcap in supporting its novel Univestin joint health ingredient. This patent brings to 151 the number of US and international patents globally awarded or pending for Unigen.

"Unigen's PhytoLogix discovery platform has yielded many proprietary bioactive natural products," said Qi Jia, PhD, lead inventor and Chief Science Officer for Unigen Pharmaceuticals. "The previously issued patent on flavans from Acacia species (Patent Number US 7,108,868 B2) and this recently allowed patent on Free-B-Ring flavonoids demonstrates the capability of Unigen's science program to discover the novel usage of flavonoids in supporting joint health."

Univestin is a proprietary blend of two individual ingredients - flavans extracted from Acacia catechu and free-b-ring flavonoids from Scutellaria baicalensis. The newly allowed Free-B-Ring flavonoid USA patent will cover this class of natural products from all potential genus and parts of high plants that include Scutellaria genera for treating osteoarthritis; securing final protection of the individual Univestin components.
