The OSI "Keyhole Logo," which combines the "O" of open and a keyhole, for unlocking source code, was created by Colin Viebrock. The Keyhole Logo and word mark are registered with the United States Patent and Trademark Office, related to: "Public advocacy to promote awareness and the importance of non-proprietary software" in Class 35, and "Educational services, namely, developing, arranging, and conducting educational conferences, programs, courses of instruction and online educational seminars in the field of non-proprietary software" in Class 41. The logo is also registered with Australia, Benelux, Canada, China, and others.

The "OSI Approved Open Source License" is also a registered trademark of the Open Source Initiative.

To promote and protect open source software and communities...

For over 20 years the Open Source Initiative (OSI) has worked to raise awareness and adoption of open source software, and build bridges between open source communities of practice. As a global non-profit, the OSI champions software freedom in society through education, collaboration, and infrastructure, stewarding the Open Source Definition (OSD), and preventing abuse of the ideals and ethos inherent to the open source movement.

Open source software is made by many people and distributed under an OSD-compliant license which grants all the rights to use, study, change, and share the software in modified and unmodified form. Software freedom is essential to enabling community development of open source software.
