ByteDance Ltd. has joined Open Invention Network (OIN) in support of OIN 2.0, adding one of the world’s largest social media and internet platform operators to the largest active patent cross-license in history. The move demonstrates ByteDance’s commitment to open source software (OSS) as core infrastructure for its global operations.
ByteDance runs a suite of more than a dozen products, among them TikTok, TikTok Shop, Lark, Douyin and Toutiao. Those platforms depend on open source technologies to operate and scale across markets and hundreds of millions of users. By joining OIN 2.0, ByteDance aligns itself with a framework built to reduce patent-related risk for the software that powers its infrastructure.
OIN was formed in 2005, to safeguard open source, and it has since assembled the largest patent non-aggression community, with membership that now exceeds 4,100 organizations. Together those members account for more than $10 trillion in annual revenues and own more than three million patents and applications.
“Internet platforms have transformed how people communicate, create, and consume content around the world. Open source technologies provide the infrastructure that enables these platforms to operate and scale globally,” said Keith Bergelt, CEO of Open Invention Network. “We are pleased to welcome ByteDance to the OIN 2.0 community. Their participation helps reduce patent-related risk for open source software and demonstrates a commitment to collaborative innovation and patent non-aggression.”
For ByteDance, membership is a statement of strategy as much as support. The company frames open source as a driver of the innovation that powers its products.
“Open source software technologies play a vital role in powering innovation,” said Juan Qi, Chief IP Counsel at ByteDance. “By joining OIN 2.0, we are demonstrating our active support for open innovation and for helping advance a collaborative environment where shared technologies thrive and evolve.”
ByteDance’s recommitment arrives as OIN advances its model. Launched in 2026, OIN 2.0 marks the organization’s shift to a sustainable, shared funding structure, one designed to expand patent protection coverage as open source spreads into new technologies and industries. Rather than a static license, OIN 2.0 delivers continuously refreshed protection to its community, broadens the range of technologies it covers and reinforces the framework to meet demands of the years ahead.
That evolution matters because open source no longer sits at the edge of enterprise computing – it is the foundation. Cloud systems, artificial intelligence platforms and global consumer applications all run on shared code, and each new participant strengthens the collective defense against patent aggression.
OIN 2.0 remains the only organization solely dedicated to mitigating patent risk in open source software. With ByteDance’s participation, its community grows stronger – and the case for collaborative innovation over litigation grows clearer.
