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
30 days
Or later version option
No
Reciprocity scope
the whole of the work, and, where the functionality is offered as a service, the Service Source Code, which includes every program used to make the service available
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.
