New LumiSort® Patent Application published

Microbix continues development of LumiSort technology and intellectual property portfolio

TORONTO, Aug. 29, 2012 /CNW/ - Microbix Biosystems Inc. (TSX:MBX), a biotechnology company developing a pipeline of innovative biological technologies and products including LumiSort® livestock semen sexing technology, has been notified by the United States Patent Office of the publication today of its latest patent application. This patent application relates to the continuing development of LumiSort and Microbix' intellectual property portfolio. The application will now undergo examination in the patent offices of the United States and key countries globally where LumiSort will be marketed.

Microbix' Chief Executive Officer, William J. Gastle, commented, "Microbix continues to focus on the development of the LumiSort patent family, to deliver an intellectual property platform that supports shareholder value. We are committed to selectively protecting the novel breakthroughs that we have achieved in our development program and to realizing their commercial potential. This newly-published application is intended to protect significant technical innovations arising from research and engineering studies to optimize the performance of the instrument."

Microbix is developing LumiSort, a next-generation instrument-based (cytometric) technology, for the preparation of sex-selected sperm cell preparations. LumiSort will provide the artificial insemination industry with a 3-fold increase in sperm cell yield and a 10-fold increase in the speed of production, while also increasing the fertility of the sexed sperm cell product. Further information on LumiSort technology is available at http://lumisort.com. Further information on the LumiSort patent estate is available on http://microbix.com//LumiSort-Patent-Estate/

The ability to separate male- and female-determining (X and Y chromosome bearing cells) sperm cells for use in artificial breeding is a significant commercial benefit to livestock producers: enhancing herd expansion and genetic improvement, while also permitting the selection of appropriate-sex production animals for production. Target markets include the food animals, equine and other selected species, where the selective reproduction of animals enhances production efficiency. Microbix' LumiSort will bring the benefits of sexed semen with improved throughput and fertility, increasing the affordability and use of sexed semen globally.
