This document summarizes a presentation given at the All Things Open Conference on protecting open source brands. The presentation discusses how open source companies can foster sharing and community while protecting their brand as their most valuable asset. It notes that open source brands face the challenge of community ownership of the brand. The presentation uses Red Hat and the Fedora Project as a case study. It explains that Fedora was created by Red Hat as a community-driven operating system, while Red Hat Enterprise Linux is corporate and supported. This created a dilemma around control of the Fedora brand, with the community wanting open usage versus Red Hat's need to tightly control the trademark.
