4 AZT: AIDS Healthcare Found. v. GlaxoSmithKline Andrews Number AIDS Advocacy Group Seeks to Invalidate AZT Patents AIDS Litigation Reporter Volume 16, Issue 3 [Published 11/4/2002] Saying that patents now held on AZT and other AIDS- related drugs by GlaxoSmithKline were obtained through fraudulent statements to the U.S. Patent Office and were based on publicly funded research, an AIDS advocacy group has amended its recent antitrust suit to include a request that the patents be invalidated so U.S. residents can take advantage of cheaper, generic versions of the drugs. AIDS Healthcare Foundation v. GlaxoSmithKline PLC et al., No TJH, first amended complaint filed (C.D. Cal., W. Div., 10/15/2002)

5 Lawsuit Challenges Patent on AZT AIDS TREATMENT NEWS No April 5, 1991 John S. James A lawsuit prepared by Public Citizen, a nonprofit public interest group founded by Ralph Nader, has challenged Burroughs Wellcome's 1988 patent on AZT (brand name Retrovir). The lawsuit claims that the patent is invalid because "the company did not conceive, develop or demonstrate the utility of the drug, nor did it name all of the inventors in its patent application," according to a March 19 press release from Public Citizen. "This lawsuit will establish the public's right to a fair price, and it gives the government a vehicle to challenge Burroughs Wellcome's monopoly." Plaintiffs include the PWA Health Group in New York, and two individuals in Washington, D. C., who are using AZT. Burroughs Wellcome's press release of the same date claimed that its scientists "were the first to conceive the use of the chemical AZT for the treatment of HIV infection in humans" -- the basis of the company's use patent, and that challenging the patent now, "more than five years after its filing...could have a chilling effect on innovation in the United States and could discourage future AIDS research." The press release also states that the company has supported "in whole or in part, more than 90 Retrovir-related clinical trials involving some 10,000 patients worldwide," and that the current price of approximately $2,200 per year for the dose of 500 mg per day "represents a 70 percent reduction in cost of therapy as a result of price decreases and reduced dosage since the drug was first marketed in 1987."AZTUnited States
