United States patent number 7,928,069 covering certain aspects of the composition of Glycosan™ hydrogels has been issued. The patent assigned to the University of Utah is licensed to BioTime’s subsidiary OrthoCyte Corporation for the manufacture of research products and for therapeutic uses when combined with human cells. The patent is of strategic value to the BioTime family of companies because it provides protection for formulations of a number of stem cell-based cellular therapies that may be developed using the Glycosan hydrogels, as well as for a stand-alone medical device designated HyStem^®-Rx.

The patent covers the thiol modification of extracellular matrix proteins such as collagen and gelatin, while another pending United States patent application in this patent family covers the thiol modification of hyaluronate and includes uses of the hydrogels in medicine. Related patent applications also are pending outside of the United States in the European Union, Canada, Japan, and Australia.

On May 10, 2011, BioTime issued a press release disclosing the issuance of the patent. A copy of the press release is filed as an Exhibit to this Report.
