License-wide duties

This license states no duties that apply to the work as a whole.

Further terms

These are the things the license says about itself beyond the acts it permits, forbids and requires: when it ends, how long there is to put a breach right, which law governs it, and so on. A term that comes from the DALICC vocabulary links to its definition.

Patent license ends if you sue
Yes. Not a ban on suing: a patent claim over the work ends the patent license, or the whole license, as the text provides.
Cure period
32 days
Field of use restriction
any purpose except providing a product that competes with the software or with a product the licensor or any of its affiliates provides using the software
Terminates on breach
Yes

Every change names the reason behind it: a finding of the content review, one of its library-wide decisions, the metadata that review wrote onto every record, or a hand edit. None of it is legal advice.

Nothing on this page is legal advice. What a license means is decided by its text; ask a legal advisor before you rely on it.
