Abstract
A digital rights management (DRM) scheme enables a user having a valid license to digital content to create one or more copies of the content. The number of copies is limited by the DRM scheme. However, if the user is not connected or connectable to the content provider or licensing party when additional copies are desired, the user is permitted to create one or more additional copies without deleting or disabling other copies even though the additional copies exceed the number otherwise permitted by the DRM scheme. The number of such “float” copies may be limited. Rights to such additional copies may be withdrawn during a subsequent connection session between the user and the content provider.
