Charles & Colvard, Ltd. (NASDAQ Global Select Market: CTHR), the sole manufacturer of created moissanite gemstones, The Most Brilliant Jewel in the World ® , today announced that the U.S. Patent and Trademark Office (the USPTO) upheld all claims under the Company’s U.S. Patent No. 5,723,391 (the ‘391 Patent) covering its silicon carbide gemstones upon conclusion of an ex parte re-examination. Throughout the ex parte re-examination process, the Company firmly believed that all of the claims of the ‘391 Patent were valid and enforceable. This successful re-confirmation of the Company’s ‘391 Patent by the USPTO follows the determination by the Australian Patent Office earlier in May that the Company’s Australian patent is both novel and inventive when faced with a similar ex parte re-examination. Charles & Colvard is confident in the strength of its entire intellectual property portfolio and is committed to vigorously defending, maintaining, and strengthening the patents that protect its moissanite gemstones and technology.
