EL SEGUNDO, Calif., July 25, 2012 (GLOBE NEWSWIRE) -- Cereplast, Inc. (Nasdaq:CERP), a leading manufacturer of proprietary biobased, sustainable bioplastics, today announced that the United States Patent and Trademark Office (USPTO) has granted the Company patent protection for high heat resistant polymer compositions having polylactic acid (PLA). USPTO-issued patent 8,222,320 expands Cereplast's growing intellectual property portfolio and protects the composition formulation invented by Cereplast Chairman and CEO Mr. Frederic Scheer and Mr. William E. Kelly of the Cereplast R&D team.
PLA has limitations in terms of melt strength and heat resistance, which has restricted its use for high temperature applications. In contrast, Cereplast's high heat PLA compositions can be industrially compostable and can retain their structural properties at temperatures greater than 165 degrees Fahrenheit (74 degrees Celsius).
Scheer stated, "This new patent strengthens the Company's leadership position in the bioplastics industry by protecting our intellectual property, and is in line with our long-term growth strategy as we continue to create grades of bioplastic resin that meet the demands of the marketplace."
