Appeals Court Upholds Depomed Patents Asserted against Purdue Pharma

March 24, 2016 at 4:28 PM EDT

NEWARK, Calif., March 24, 2016 (GLOBE NEWSWIRE) -- Depomed (NASDAQ:DEPO) announced today that the U.S. Court of Appeals for the Federal Circuit has affirmed the decisions of the Patent Trial and Appeal Board of the United States Patent and Trademark Office (PTAB) confirming the patentability of two Depomed patents (U.S. Patent Nos. 6,340,475 and 6,635,280).  In January 2013, Depomed sued Purdue Pharma (“Purdue”) in New Jersey Federal District Court for infringement of the patents by Purdue's reformulated OxyContin® (oxycodone hcl extended release tablets) product. Purdue subsequently challenged the patents in inter partes review proceedings (IPRs) before the PTAB.  The PTAB upheld the patents, and Purdue had appealed the decision.  As a result of the decision of the appellate court, Depomed expects to resume its lawsuit against Purdue alleging infringement of these patents and is requesting that a stay related to the IPR be lifted.  Purdue will not be able to assert invalidity arguments in this trial based on prior art it raised or could have raised in the inter partes review proceedings.   

“This decision acknowledges the innovation of our patents and builds on our successful track record of aggressively enforcing our intellectual property estate,” said Jim Schoeneck president and CEO of Depomed. “We look forward to continuing our litigation against Purdue.”
