The '''BitTorrent Open Source LicenceLicense''', is derived from the [[Jabber Open Source License]], which is an [[Open Source Initiative]] (OSI) approved license. Former versions of the [[BitTorrent (software)|BitTorrent client]] (before 6.0) and related pieces of software are licensed under this License.<ref>{{cite whichweb|url=http://www2.bittorrent.com/legal/bittorrent-open-source-license|title=BitTorrent isOpen availableSource here:License - BitTorrent|date=9 August 2011|archive-url=https://web.archive.org/web/20110809153637/http://www2.bittorrent.com/legal/bittorrent-open-source-license|access-date=2 April 2019|archive-date=2011-08-09}}</ref>
A noteworthy aspect of the BitTorrent Open Source LicenceLicense is that it does not grant trademark licencelicense. The trademark "BitTorrent" is owned by the company BitTorrent Inc. and is governed by the Trademark Use Guidelines.<ref>{{cite web|url=http://bittorrent.com/trademark.html|title=BitTorrent|date=16 July 2006|archive-url=https://web.archive.org/web/20060716194903/http://bittorrent.com/trademark.html|access-date=2 April 2019|archive-date=2006-07-16}}</ref>
