Open Source License Agreement

An Open Source License Agreement is a copyright license that permits users to freely use, modify, and distribute software source code. Unlike proprietary licenses, open source licenses grant broad permissions while imposing certain conditions. Popular open source licenses include MIT License (permissive, minimal restrictions), Apache License (includes patent grants), GPL (copyleft, requires derivative works to be open source), and BSD License (permissive, allows proprietary derivatives). The license typically grants rights to: use the software for any purpose, study and modify source code, distribute copies, and distribute modified versions. Some licenses (copyleft) require derivative works to be distributed under the same license terms. Open source doesn't mean "no rights" - the copyright holder retains ownership and the license terms must be followed. Companies using open source software must ensure compliance with license obligations to avoid copyright infringement and protect their proprietary code.
