HapMap Data Access Agreement
"The International HapMap Project was a private–public collaboration established to create a haplotype map of the human genome.
Before December 2004, researchers wishing to access the Project’s online database had to agree to set of “click-wrap” conditions designed to discourage database users from filing patent applications that would block other users’ access to the data. According to a notice on the site, the software GPL directly inspired the terms of the click wrap agreement.
Implementation was problematic, however, and the requirement was withdrawn before the Project was completed." (http://opensourcebiotech.anu.edu.au/Open_Source_Biotechnology/Practice.html)
