Now that open source software is blossoming around the world, it is crucial to understand how open source licenses work—and their solid legal foundations. Open Source Initiative general counsel Lawrence Rosen presents a plain-English guide to open source law for developers, managers, users, and lawyers.

Coverage includes:

• Explanation of why the SCO litigation and other attacks won’t derail open source
• Dispelling the myths of open source licensing
• Intellectual property law for nonlawyers: ownership and licensing of copyrights, patents, and trademarks
• “Academic licenses”: BSD, MIT, Apache, and beyond
• The “reciprocal bargain” at the heart of the GPL
• Alternative licenses: Mozilla, CPL, OSL and AFL
• Benefits of open source, and the obligations and risks facing businesses that deploy open source software
• Choosing the right license: considering business models, product architecture, IP ownership,
license compatibility issues, relicensing, and more
• Enforcing the terms and conditions of open source licenses
• Shared source, eventual source, and other alternative models to open source
• Protecting yourself against lawsuits
