Atrium Files Counterclaims Indicating Genzyme Patents Are Invalid
Hudson, NH - June 7, 2001 - Atrium Medical, the “Number 1” best selling Cardiothoracic chest drain company in the U.S., has filed counterclaims in a lawsuit brought by its competitor Genzyme in November 2000.  Genzyme’s claims of infringement by Atrium’s mechanical vacuum control chest drain products and patient protection technology, have not gone unchallenged by Atrium.  Atrium has asserted counterclaims against Genzyme alleging that all five patents at issue are not infringed, that all five patents are invalid, and that four of the five patents are unenforceable because they were obtained through inequitable conduct before the United States Patent and Trademark Office. 

Atrium Medical has been a pioneer in the Thoracic Drainage business since its founding in 1981.  During these past two decades, Atrium has consistently introduced leading-edge products for open heart and thoracic surgery, blood vessel and hernia repair.  Atrium is widely known for its excellence in service and innovation in the Cardiovascular, General and Thoracic Surgery marketplace.  While Atrium continues to experience growth in this healthcare sector, Genzyme Corporation and Genzyme Biosurgery (collectively, “Genzyme”) have continued to experience declining chest drain sales and profitability from such products over the past few years.  According to the company’s CEO and President Steve Herweck, the lawsuit filed by Genzyme in November 2000 is directed at slowing our momentum.  Atrium’s current sales strength and clinical performance in sophisticated chest drainage devices and thoracic catheters are unmatched by those at Genzyme.  Both items are used to modulate vacuum to the chest following surgery or trauma, principally for fluid evacuation around the heart and lungs.  

Moreover, this is the second time that what is now Genzyme’s chest drainage device business has resorted to the courts in an attempt to impact Atrium and its products to customers and national accounts.  In 1995, Atrium won a landmark chest drain patent infringement lawsuit brought by Genzyme’s predecessor, Deknatel, Inc.  In Federal Court, a jury and judge not only found that Atrium did not infringe the Deknatel chest drain patent, but also concluded that the principal patent involved in that case was invalid.  Atrium continues to vigorously defend itself in this lawsuit as well and is confident that it will triumph over Genzyme’s claims of infringement.  

As the largest and most successful corporate chest drain partner for many of the nation’s Group Purchasing Organizations (GPO’s) Atrium’s “National Account” presence and high compliance further demonstrates its clinical superiority, quality and customer preference.  Together with the support of the largest “dedicated” Thoracic Drainage sales force in the U.S., Atrium will continue its course as the best selling Chest Drain company.
