Rosetta Genomics Receives Additional U.S. Patent Protection for the Cancer Origin Test™

Composition of matter patent protects a core element of its diagnostic assay for the accurate identification of the tissue of origin in cancers of unknown or uncertain primary

PRINCETON, N.J. & REHOVOT, Israel--()--Rosetta Genomics Ltd. (NASDAQ: ROSG), a leading developer and provider of microRNA-based molecular and other diagnostics, announces that the Company has received a Notice of Allowance from the United States Patent and Trademark Office for U.S. patent application No. 13/986,516 titled, “microRNAs and uses thereof.”

The composition of matter patent claims hsa-miR-509-3p, its complement and a sequence at least 90% identical to it, as well as a primer and a vector comprising this microRNA. This patent specifically covers one essential marker in the Rosetta Cancer Origin Test™.

“We continue to make inroads building patent protection around our microRNA technology platforms and products. This new patent allowance further strengthens and secures the coverage for one of our lead products, the Rosetta Cancer Origin Test™, which can accurately identify the primary tumor type in primary and metastatic cancer including cancer of unknown or uncertain primary,” said Kenneth A. Berlin, President and Chief Executive Officer of Rosetta Genomics. “Our growing intellectual property position continues to protect and solidify our global leadership position in microRNA biomarker technology while providing additional revenue generating opportunities for us and enhancing our leadership position in the commercialization of differentiated and proprietary content in the area of personalized medicine.”

Rosetta Genomics has 42 issued patents, seven allowed patents and 43 patents pending worldwide.

About Rosetta Cancer Testing Services

Rosetta Cancer Tests are a series of microRNA-based diagnostic testing services offered by Rosetta Genomics. The Rosetta Cancer Origin Test can accurately identify the primary tumor type in primary and metastatic cancer including cancer of unknown or uncertain primary (CUP). The Rosetta Lung Cancer Test accurately identifies the four main subtypes of lung cancer using small amounts of tumor cells. The Rosetta Kidney Cancer Test accurately classifies the four most common kidney tumors: clear cell renal cell carcinoma (RCC), papillary RCC, chromophobe RCC and oncocytoma. Rosetta’s assays are designed to provide objective diagnostic data. In the U.S. alone, Rosetta Genomics estimates that 200,000 patients a year may benefit from the Rosetta Cancer Origin Test, 62,000 from the Rosetta Kidney Cancer Test™ and 222,000 patients from the Rosetta Lung Cancer Test. The Company’s assays are offered directly by Rosetta Genomics in the U.S., and through distributors around the world. In addition to its proprietary products, the Company markets the Rosetta Genomics PGxOneand EGFR and KRAS tests for Admera Health. With the recent acquisition of PersonalizeDx, the company now offers a broader menu of molecular and other assays for bladder, lung, prostate and breast cancer patients.
