Rosetta Genomics Receives First Patent Allowance in Japan

PRINCETON, N.J. & REHOVOT, Israel

Rosetta Genomics Ltd. (NASDAQ: ROSG), a leading developer and provider of microRNA-based molecular diagnostics, announces that the Company received a Notice of Allowance from the Japan Patent Office (JPO) for Japanese Patent Application No. 2007-512601, which relates to human miR-92b. The composition of matter patent to be issued claims the sequence of miR-92b and its complement, as well as its use as a probe, including in biochips. miR-92b has been shown to be elevated in cancer and is a key element of the Company’s lead oncology diagnostic, the Rosetta Cancer Origin Test™ (COT).

The claims allowed cover an isolated nucleic acid having the sequence of human miR-92b and its complement, as well as to variants being at least 90% identical to miR-92b. In addition, the allowed claims encompass a vector and a probe comprising miR-92b, a composition and a biochip comprising probes specific to miR-92b.

“The extension of our patent protection to cover composition of matter for our oncology diagnostics in Japan demonstrates our commitment to broadly protect our proprietary microRNA technology platform,” noted Kenneth A. Berlin, President and Chief Executive Officer of Rosetta Genomics. “It also supports our comprehensive oncology strategy for the worldwide development and commercialization of microRNA-based diagnostics, therapeutics and biomarkers that can enhance clinicians’ ability to identify and treat cancers and we look forward to monetizing this latest addition to our patent estate through licenses or partnerships in Japan, a significant market for oncology diagnostics and therapeutics.”

“We continue to protect and build upon our leading intellectual property position in microRNA technology and this newly allowed patent expands, strengthens and complements our growing portfolio of over 40 patents worldwide,” added Mr. Berlin.

About Rosetta Cancer Testing Services

Rosetta Cancer Tests are a series of microRNA-based diagnostic testing services offered by Rosetta Genomics. The 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; it is the treating physician’s responsibility to diagnose and administer the appropriate treatment. In the U.S. alone, Rosetta Genomics estimates that 200,000 patients a year may benefit from the Rosetta Cancer Origin Test^™, 65,000 from the Rosetta Kidney Cancer Test^™ and 226,000 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. For more information, please visit www.rosettagenomics.com.
