In 2016, the Chan Zuckerberg Initiative gave $600 million to create the tax-exempt charity Chan Zuckerberg Biohub, a collaborative research space in San Francisco's Mission Bay District near the University of California, San Francisco, with the intent to foster interaction and collaboration between scientists at UCSF, University of California, Berkeley, and Stanford University. Intellectual property generated would be jointly owned by Biohub and the discoverer's home institution. Unlike foundations like the Bill and Melinda Gates Foundation which open up all research funded to unrestricted access and reuse by the public, Biohub retains the right to commercialize any research it funds. Inventors will have the option of making their discoveries open-source, with permission from Biohub. To increase access to scientific research and promote open science, CZ Biohub requires its investigators and staff scientists to publish submitted manuscripts and related data on preprints servers like bioRxiv.
