Olicense

Olicense is a fictional open-source software license created for educational and illustrative purposes in discussions of software licensing. It is designed to help explain how permissive licenses handle attribution, patent risk, and interoperability with other licenses.

Grant and scope: It grants permission to use, copy, modify, merge, publish, distribute, sublicense, and sell copies of the software, and to permit persons to whom the software is furnished to do so, subject to certain conditions.

Conditions: The license requires preserving copyright notices and this license text in all copies or substantial portions of the software, including modified versions; any derivative works must be clearly marked as such.

Patent and trademark: The license includes a patent grant to implement essential patent claims of contributors; it also clarifies that no trademark rights are granted.

Limitations: The software is provided "as is" without warranty; no liability; disclaimers; use at your own risk.

Relation to other licenses and history: In educational materials, Olicense is described as permissive and easy to interoperate with; it is explicitly fictional and has no official legal status outside learning contexts.
