Cleversafe Assigned Two Patents

Data distribution utilizing unique write parameters in a dispersed storage system, 2/ dispersed storage unit selection

Cleversafe, Inc., Chicago, IL, has been assigned a patent (8,291,277 developed by Timothy W. Markison, Mesa, AZ, and Gary W. Grube, Barrington Hills, IL, for a "data distribution utilizing unique write parameters in a dispersed storage system."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A method begins by a processing module receiving a plurality of record requests to record a broadcast of data. The method continues with the processing module encoding the data using an error coding dispersal storage function to produce a plurality of sets of encoded data slices. The method continues with the processing module generating a list of requesting device identities corresponding to the plurality of requests and storing the plurality of sets of encoded data slices and the list of requesting device identities in a dispersed storage network memory. The method continues with the processing module receiving a playback request from a device identified in the list of requesting device identities, generating a unique retrieval matrix for the device, and outputting a unique plurality of sets of encoded data slices from the plurality of sets of encoded data slices in accordance with the unique retrieval matrix."

The patent application was filed on July 23, 2010 (12/842,949). .

Dispersed storage unit selection

Cleversafe, Inc., Chicago, IL, has been assigned a patent (8,281,182) developed by Jason K. Resch and S. Christopher Gladwin, Chicago, IL for a "dispersed storage unit selection."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A dispersed storage device for use within a dispersed storage network operates to select a set of dispersed storage units for storage of a data object by slicing an encoded data segment of a data object into error coded data slices, determining slice metadata for the error coded data slices, determining memory characteristics of dispersed storage units capable of storing the error coded data slices and selecting the set of dispersed storage units for storing the error coded data slices based on the slice metadata and the memory characteristics."

The patent application was filed on May 13, 2010 (12/779,658).
