Concurrent use license

Definition
A concurrent use license is a license under which a vendor grants the licensee the right to use software licensed under a single user license on more than one computer, as long as the licensee does not use the software on more than one computer at the same time. For example, a vendor might allow the licensee to load the software on both a desktop and a laptop (or tablet) so the licensee could use the software in his/her office and also while traveling or at home.
