IntelGenx Receives Positive Ruling in Patent Litigation Hearing

SAINT LAURENT, QUEBEC, Jan 4, 2011 (Marketwire via COMTEX) -- IntelGenx Corp. today announced that the United States District Court of Delaware has ruled in favor of IntelGenx regarding claim construction for the two patent terms at issue in the patent infringement action brought forward by Biovail Laboratories International SLR ("Biovail") under the Drug Price Competition and Patent Term Restoration Act ("Hatch-Waxman Act"). The ruling arises from a special proceeding required under U.S. patent law called a "Markman Hearing" where both sides present to the court their arguments on how they believe the patent terms at issue should be interpreted.

"We are very pleased that the court has fully adopted our interpretation of the claim language at issue," commented Horst Zerbe, President and CEO of IntelGenx. "We have always steadfastly argued that CPI-300, our proprietary high-dose bupropion product, does not infringe on any properly-interpreted claims of the asserted patents, and now have a ruling that should allow us ultimately to obtain a ruling to that effect."

Dr. Zerbe added, "We believe CPI-300 would offer compliance and cost benefits to the U.S. consumer and we will move expeditiously to get it to market. To that end, we are in the final steps of accumulating the data necessary to address FDA's questions from the Complete Response Letter and submit our response to the Agency in the coming months."

On August 21, 2009 the Company announced that Biovail had filed a complaint with the District Court of Delaware for infringement on its U.S. Patent No. 6,096,341. The Markman Hearing was subsequently held on June 22, 2010.
