MonoSol Rx Strengthens Canadian Patent Portfolio for PharmFilm®

New Patent Issue Covers Multiple Areas Related to Drug-Containing Film Products

Warren, NJ (October 11, 2011) – MonoSol Rx, LLC (“MonoSol Rx”), the developer of PharmFilm® drug delivery technology, announced that it has been granted Canadian patent No. 2,473,967 from the Canadian Intellectual Property Office, providing intellectual property protection in Canada for the Company’s film products and methods of their preparation.  The issued patent is comprised of 106 claims, of which 19 are independent.  The claims cover Monosol Rx’s proprietary technology, including film manufacturing processes, use of films to deliver actives to mammals, two layer films and film compositions.  Important aspects of the patented technology allow manufacturers to maintain content uniformity throughout the film and create products that have a water content of 10% or less.

A. Mark Schobel, President and Chief Executive Officer of MonoSol Rx, stated, “We intend to maintain our leadership position in the development of drug-containing film products.  Issuance of this critical patent in Canada continues our tradition of protecting our intellectual property and will enhance our ability to market PharmFilm®products competitively in this country in the future.  As we have in the United States against BioDelivery Sciences International’s (“BDSI”) ONSOLIS product, we will continue to aggressively assert our patent rights regarding products and companies that are infringing any of our patent estate.”
