SUNNYVALE, Calif. – Arrayit Corporation (OTCBB:ARYC – News), a leader in life sciences and healthcare technology, announced today that the company has received a registered trademark Notice of Allowance from the United States Patent and Trademark Office (USPTO) for the company’s OvaDx® pre-symptomatic ovarian cancer test. The June 29th, 2010 issuance of USPTO serial number 77891798 grants Arrayit exclusive nationwide rights to use the mark on or in connection with scientific, research, medical laboratory and clinical diagnostics uses of OvaDx® for the full lifetime of the product.

Arrayit’s OvaDx®, the market’s first comprehensive diagnostic screening test for ovarian cancer, uses approximately 100 proteomic biomarkers to identify molecular beacons of ovarian cancer that accumulate in the bloodstream as soon as an ovarian tumor begins to develop. OvaDx® detects both early and late stage ovarian cancer with high sensitivity and specificity using Arrayit’s proprietary microarrays, which are tiny medical devices that screen large numbers of patient samples in a highly miniaturized and automated manner. OvaDx® leverages Arrayit’s patented manufacturing technology and will be marketed and sold upon FDA approval by the company’s subsidiary Arrayit Diagnostics, Inc.

Arrayit CEO Rene Schena states, “We are pleased to receive a Notice of Allowance from the USPTO regarding our registered trademark. This achievement marks another important step in the commercialization of OvaDx®.”
