License details are here:

<http://www.sqlite.org/copyright.html>

tl;dr version: no license is required or even requested.  You can buy one if 
some part of your organisation requires it for legal purposes.

There's a list of well-known users here:

<http://www.sqlite.org/famous.html>

However, being truly public domain (not GPL, copyleft, or anything like that) 
means no license is needed, or asked for.  Consequently it's found in countless 
products from companies which would never organise the business relationships 
necessary for obtaining and paying for a license.  For instance, I recently 
found the standards SQLite headertext in the firmware update for a TV recorder, 
which is made by an obscure Korean company which would probably not pay a 
license fee.

I don't think there's much a company could do to misuse SQLite.  Claiming 
authorship or ownership over it would be illegal (in my country, at least) but 
apart from that I can't think of anything.
