This article addresses how open access to DNA, RNA and amino acid sequences might be reconciled with the benefit-sharing obligations under the United Nations' Convention on Biological Diversity and its Nagoya Protocol, the Food and Agriculture Organization of the United Nations' International Treaty on Plant Genetic Resources for Food and Agriculture, and the World Health Organization's Pandemic Influenza Preparedness Framework for the Sharing of Influenza Viruses and Access to Vaccines and Other Benefits. Tracing the evolution of open access databases, the article posits models for reconciling open access and benefit sharing; the article concludes, however, that none of the proposed solutions-monitoring and tracing, the contract model, and the copyright and database right model-provides a perfect solution. Each model does, however, suggest that open access to these sequences might be at least partially reconciled with benefit sharing.
