International Classification:

A61K 4500

US Classification:

424 851, 435 6, 435 71, 514 12, 530350, 530386, 5303881

Abstract:

The present invention is directed to novel methods for assaying for modulators of GADD45 polypeptide activity. The invention also provides means to sensitize a proliferating cell to a DNA base-damaging agent by administration of novel inhibitors of GADD45 polypeptide activity. The invention further provides polypeptides which interfere with the ability of Cdc2/cyclin B1 complexes to cause a pause at the G2/M stage of the cell cycle in response to GADD45, and nucleic acids which encode such polypeptides.

International Classification:

G06F 1760

US Classification:

705 51, 705 1, 705 54

Abstract:

Usage rights to digital content are dynamically assigned. Various dynamic conditions are monitored and the usage rights are adjusted in a predetermined manner based on the status of dynamic conditions. The dynamic conditions include the time of day, the load on a server or network, or the like. The resolution of an image can be determined based on the conditions and the image can be rendered using subband decomposition techniques to permit variable resolution images to be constructed on the fly.

International Classification:

G06F017/60

US Classification:

705 51, 705 26, 713182

Abstract:

Usage rights for a digital work are established prior to creation of the corresponding content. The rights can be associated with the content after the content is created. A content creation, such as a video recorder or a still camera, device can store labels of the rights and can associate usage rights with content in real time as the content is created.

US Classification:

713168, 713182, 713193, 713200, 713201

Abstract:

Digital rights management allows one or more of usage rights and delegation rights to be associated with a document. Through the use of the usage rights and the delegation rights, a hierarchy of rights associated with a document is created that provides a tree-type structure of rights extending from the content owner down through one or more users.

Abstract:

Flags are used to mark portions of content in a digital work to permit marking or demarcation of portions of the document. The demarcated portions can be handled in various ways. For example, different usage rights can be applied to demarcated portions, the demarcated portionis can be culled for use as a summary, or the like. The flags can be used to demarcate portions of content that has been downloaded to keep track of payment and download status and thus add flexibility to electronic distribution of content. A flag usage rights element can be attached to limit and control access to flags in a desired manner.
