Advancis Pharmaceutical Receives Judgment in Trademark Infringement Lawsuit

Federal Judge Rules Advancis Name Infringes Sanofi-aventis Trademark

GERMANTOWN, Md., Sept. 28 (HSMN NewsFeed) -- Advancis Pharmaceutical Corporation (Nasdaq: AVNC ), a pharmaceutical company focused on developing and commercializing novel anti-infective products, today announced that the United States District Court for the District of Delaware has issued an opinion and order in favor of Sanofi-aventis ruling that Advancis is infringing the Sanofi-aventis trademark.

In December 2003, Aventis and Aventis Pharmaceuticals Inc., now part of Sanofi-aventis, brought an action against Advancis, alleging, in essence, that Advancis is infringing the plaintiff's trademark and seeking injunctive relief. A trial was held in May, 2005.

The court's decision, dated September 26, 2006, ruled in favor of the plaintiff and deferred an injunction, asking the parties to jointly submit a proposed order by October 23, 2006. Advancis is disappointed with the court's decision and is currently reviewing its legal options, including the possibility of an appeal. No monetary damages were associated with the decision.

ABOUT ADVANCIS PHARMACEUTICAL:

Advancis Pharmaceutical Corporation (Nasdaq: AVNC ) is a pharmaceutical company focused on the development and commercialization of anti-infective drug products that fulfill substantial unmet medical needs in the treatment of infectious disease. The Company is developing a portfolio of anti-infective drugs based on its novel biological finding that bacteria exposed to antibiotics in frontloaded staccato bursts, or "pulses," are killed more efficiently and effectively than those under standard treatment regimens. Based on this finding, Advancis has developed a proprietary, once-a-day pulsatile delivery technology called PULSYS. By examining the resistance patterns of bacteria and applying its delivery technologies, Advancis has the potential to redefine infectious disease therapy and significantly improve drug efficacy, shorten length of therapy, and reduce drug resistance versus currently available antibacterial products.
