Established in 2005, Open Invention Network (OIN) is the world’s largest patent non-aggression community and free defensive patent pool.

We remove patent friction in core Open Source technologies, which drives higher levels of innovation. Open Source Software (OSS) distills the collective intelligence of a global community.


We enable freedom of action for Open Invention Network community members and users of Linux/OSS-based technology through our patent non-aggression, cross-license in the Linux System, which defines the commitment of all community members.

We will continue to grow our worldwide membership and the Linux System over time.


We will execute our mission by growing our community membership and engaging with companies of all types — from start-ups to Fortune 100 enterprises — across diverse industries.

We will continue updating the Linux System through a conservative, consensus-driven process to keep up with technological advances.

We will actively monitor for patent-related threats to Linux and adjacent Open Source technologies and encourage open source community Intellectual Property (IP)-related initiatives.

We will continue to promote and educate our community on complementary defensive IP strategies and support key Open Source projects.
