DUSA Pharmaceuticals Sues Additional Physicians For Infringement Of Its Levulan'R' Photodynamic Therapy Patents.
DUSA Pharmaceuticals, Inc.(R) (NASDAQ NMS:DUSA) announced today that it has filed additional lawsuits against physicians in California, Michigan, and Massachusetts, to prevent their continued infringement of DUSA's patents on methods of treating various disorders with photodynamic therapy (PDT). DUSA's patents cover the use of compounds such as aminolevulinic acid (ALA) with PDT to treat actinic keratosis, basal cell carcinoma, acne and other dermatological conditions. The suits allege that ALA obtained from sources other than DUSA Pharmaceuticals is being used by physicians, without license from DUSA, to perform treatments that are covered under patents exclusively licensed by DUSA, resulting in direct infringement of these patent(s).
In November, 2005 DUSA filed similar patent infringement suits against doctors in California, Florida, and Tennessee. To date, DUSA has obtained consent judgments in two of these suits with the defendant physicians admitting to infringing DUSA's patents and agreeing to cease their illegal conduct. In one of these cases, the defendant physician also admitted to illegally using DUSA's Levulan(R) trademark in connection with his infringing activities and agreed to cease this conduct as well. Of the two cases remaining active from November, 2005, one defendant failed to offer a defense and defaulted, and the other case is still pending.
"We have an obligation to protect our Levulan(R) franchise from illegal exploitation of our intellectual property and to protect our valued customers from unfair competition from those who infringe our patents," said Robert Doman, DUSA's President and Chief Operating Officer. "It is unfortunate that we must take action against these physicians, but, even in the face of our patent position, compounding pharmacies continue to place physicians at risk of patent infringement by making ALA available. We will continue to actively monitor the situation with compounded ALA in the medical community and will take systematic action to prevent further infringement of our patents."
