As of npm 3.10 you have to use UNLICENSED:
{ "license": "UNLICENSED"}
or
{ "license": "SEE LICENSE IN <filename>"}
The value of license must either one of the options above or the identifier for the license from this list of SPDX licenses. Any other value is not valid.
The following is no longer valid for current versions of npm
For npm versions before 3.10 you may use:
{ "license" : "LicenseRef-LICENSE" }
Then include a LICENSE file at the top level of the package. It could be as short as:
(c) Copyright 2015 person or company, all rights reserved.
But you might want to be more explicit about what is not allowed.

This does not exactly answer your question, but what about:
{
"license": "Proprietary",
"private": true,
}
