MITApache20

MITApache20 is a proposed dual-license model that combines elements of the MIT License and the Apache License 2.0 to provide a permissive, patent-respecting framework for open-source software. First proposed in discussions around 2020, the concept aims to address gaps in license compatibility and patent clarity by offering a single license wrapper that can be applied to software projects.

In terms of terms, MITApache20 grants broad rights to use, copy, modify, merge, publish, distribute, sublicense, and sell copies of the software. It requires attribution and preservation of the original license notices. It includes a patent grant that mirrors Apache 2.0, giving users a license to any patents held by contributors that cover the contributed code, and it disclaims warranties and liabilities.

Differences from the MIT and Apache licenses: MITApache20 is designed to unify the obligations, so downstream users can rely on MIT-like simplicity while gaining explicit patent rights similar to Apache 2.0. It typically requires that any distributed version retains the respective license texts and notices. The license is designed to be permissive, without imposing copyleft obligations.

Compatibility and adoption: Because MITApache20 explicitly merges terms from MIT and Apache 2.0, it is presented as compatible with both licenses, enabling inclusion of either MIT- or Apache-licensed components into a project under MITApache20 and vice versa (subject to the terms). Adoption has been limited; several organizations view it as a theoretical model rather than an established standard, with debates about legal enforceability and jurisdictional interpretation.

Critics note potential confusion around dual obligations and the need for clear contributor consent for combined licensing. Supporters argue it streamlines licensing decisions for modern software with patent concerns. See also MIT License; Apache License 2.0; software licensing.
