ABSTRACT:
A technique for content redistribution. Digital content is packaged, and the package is associated with a first license that permits usage of the content on a first device. The first license also specifies the conditions upon which the content may be redistributed and licensed for use on a second device. When a content package is sent to the second device, the second device engages in a re-licensing transaction to obtain a second license that permits use of the content on the second device. Creation of the second license takes place according to conditions specified in the first license. For example, these conditions may specify a price for the second license, and/or a requirement that a portion of the purchase price be paid back to the owner of the first license, and/or a requirement that the first license be revoked upon creation of the second license.
