Legal Definitions - MPL

MPL

MPL stands for Mozilla Public License, which is an open-source license that allows software users to modify and publicly distribute the software. However, users must release the changed software under the same copyright as the original source code and release all claims to patent rights. The license prohibits the sale of modified software unless it is included in a package with other software.

• A software developer modifies the source code of a program licensed under MPL and publicly distributes the modified software. The developer must release the changed software under the same copyright as the original source code and release all claims to patent rights.
• A company includes modified software licensed under MPL in a package with other software and sells the package. This is allowed under MPL.

The examples illustrate how MPL works. The license allows users to modify and distribute the software, but they must follow certain conditions, such as releasing the changed software under the same copyright as the original source code and releasing all claims to patent rights. The license also prohibits the sale of modified software unless it is included in a package with other software.
