Blue Oak Council opens the software commons up to those who can’t find or afford specialized legal help by bringing experienced lawyer-technologists together to publish free, practical materials about software licenses.

Permissive License List

Blue Oak maintains a rated list of permissive software licenses

Permissive licenses are the bread and butter of software development: simple, effective, and on just about everyone’s “go” list. But most information about free and open source software focuses on other, more complex licenses. The Council publishes this list to identify permissive licenses, so that everyone can recognize, rely on, and use them without expensive legal help.

I've copied the Gold and Silver sections below.

Gold

These licenses address patents explicitly, use robust language, and require only simple notice of license terms and copyright notices.

Silver

These licenses use robust language but either fail to address patents explicitly or require more than simple notice of license terms and copyright notices.
