Pharmaceutical giants like Pfizer and GlaxoSmithKline hold the future welfare of poor people living with HIV/AIDS in their hands, argues...Medicins Sans Frontiers (MSF), [which] has launched a new e-mail campaign to pressure pharmaceutical companies to share their patent rights of certain antiretroviral HIV/AIDS drugs…[P]atents held by different companies on specific HIV drugs would be made available to other companies for both production and development. The companies that own the patent rights would in turn receive royalties…a patent pool would make HIV drugs more readily available for distribution…much more affordable… MSF's patent campaign is targeting Abbot Laboratories, Boehringer Ingelheim, Bristol-Myers Squibb, Johnson & Johnson, Gilead Sciences, GlaxoSmithKline, Merck & Co., Pfizer and Sequoia Pharmaceuticals.
