Every Thursday, the US Patent and Trademark Office publishes pending patent applications. Publication has no bearing on whether a patent will eventually be issued based on the application. Still, issued patents and published applications are often indicators of what people have been thinking about and the kinds of things that individuals or companies believe may be useful to them in the future.
Today I found more than the usual number of interesting applications, so rather than presenting the abstracts of two, today is a "three-fur". First is one assigned to Macrovision regarding the interdiction of unauthorized copying in a decentralized network. Second is one assigned to Microsoft regarding secure data paths. Third is one assigned to Motorola regarding recording protected information on a handset.
20050091167, "Interdiction of unauthorized copying in a decentralized network," assigned to Macrovision.
An interdiction system includes software agents masquerading as nodes in a decentralized network, a query matcher that receives search results captured by the software agents and reports matches with protected files back to the software agents, and a central coordinating authority that coordinates activities of the software agents by sending instructions to the software agents specifying actions to be taken. Possible activities and related interdicting methods include manipulating search results before forwarding them on in the network, quarantining selected nodes in the network, performing file impersonations such as transferring synthesized decoys, performing file transfer attenuation, and hash spoofing.
20050091488, "Protected media path and refusal response enabler," assigned to Microsoft.
In a protected media path for delivering content from a source to a sink, a source authority (SOTA) on behalf of the source decides with regard to a policy corresponding to the content that a particular type of action with the content is to be refused, and provides a particular enabler to an application. The provided enabler includes information and methods necessary for the application to obtain data necessary to respond to the refusal. The application receives the enabler at an interface thereof and the interface applies a common interaction procedure to run the enabler to obtain the data necessary to respond to the refusal.
20050091683, "Method and apparatus for recording and editing digital broadcast content," assigned to Motorola
A wireless mobile terminal (10) and method for utilizing digital broadcast content records (204) selected digital broadcast content as received, for example, by a digital broadcast receiver (16) and provides editing of the selected digital broadcast content based on digital rights management data to generate customized clips of information. The selected digital broadcast content is edited (206) to produce mobile terminal edited digital broadcast content that may be, for example, distributed (208) by the mobile terminal to a plurality of peer devices. A broadcast content editor (24) allows for the editing of clips of content wherein the edited clips are then stored in memory as recorded clips for distribution by the mobile terminal. In another embodiment, a network element is remotely controlled by the mobile terminal to effect editing through the mobile terminal at the network element.
