Custom OFL License Explained

1 fonts under this license

Overview of OFL-Based Company Licenses

Custom OFL denotes font licenses that adopt the core framework of the SIL Open Font License (OFL 1.1) while incorporating company-specific stipulations, trademark boundaries, or brand distribution clauses (such as Woowa Brothers' Baemin typeface series in Korea).

Because they are rooted in the open-source OFL framework, these fonts generally provide generous permissions for commercial projects, digital products, and web embedding. However, corporate font releases frequently append provisions regarding the protection of their corporate marks and trademark identities.

Key Corporate Caveats to Watch

Trademark & Brand Protection
- The creator’s corporate identity (e.g., brand name, mascot, registered trade dress) remains strictly protected. Modified or repackaged font releases must use distinct names that do not imply official brand endorsement.
Reputational & Harmful Use Restrictions
- Company licenses often forbid using their branded typefaces in illegal, derogatory, or brand-damaging publications.
No Standalone Monetization
- In alignment with SIL OFL Clause 1, you cannot charge a separate fee for the font binaries themselves.
