Cleversafe Assigned Six Patents

Updating data stored in dispersed storage network
Cleversafe, Inc., Chicago, IL has been assigned a patent (8,782,492) developed by Jason K. Resch and Wesley Leggette, Chicago, IL, for “updating data stored in a dispersed storage network.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method begins by a dispersed storage (DS) processing module receiving a modified data object, wherein the modified data object is a modified version of a data object and the data object is divided into a plurality of data segments and stored in the DSN. The method continues with the DS processing module mapping portions of the modified data object to the plurality of data segments that includes creating a middle data segment of a second plurality of data segments based on a corresponding middle data segment of the plurality of data segments when a portion of the portions corresponds to middle data of the modified data object. The method continues with the DS processing module encoding the middle data segment using a dispersed storage error coding function to produce an encoded data segment and overwriting the corresponding middle data segment with the encoded data segment in the DSN.”

The patent application was filed on Aug. 17, 2012 (13/588,350).

Obtaining signed certificate for dispersed storage network
Cleversafe, Inc., Chicago, IL has been assigned a patent (8,776,186) developed by three co-inventors for “obtaining a signed certificate for a dispersed storage network.”

The co-inventors are Jason K. Resch, Wesley Leggette and Andrew Baptist, Chicago, IL.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method begins by a dispersed storage (DS) processing module generating a certificate signing request (CSR) that includes a certificate and a certificate extension, wherein the certificate includes information regarding a requesting device and wherein the certificate extension includes information regarding an accessible dispersed storage network (DSN) address range for the requesting device. The method continues with the DS processing module outputting the CSR to a certificate authority of a DSN and receiving a signed certificate from the certificate authority, wherein the signed certificate includes a certification signature of the certificate authority authenticating the certificate and the certificate extension. The method continues with the DS processing module storing the signed certificate for use when generating a DSN access request, wherein the DSN access request is requesting access to dispersed storage error encoded data in the DSN at an address within the accessible DSN address range.“

The patent application was filed on Aug. 17, 2012 (13/588,259).

Migrating encoded data slices
from re-provisioned memory device of dispersed storage network memory
Cleversafe, Inc., Chicago, IL has been assigned a patent (8,762,793) developed by five co-inventors for “migrating encoded data slices from a re-provisioned memory device of a dispersed storage network memory.”

The co-inventors are Gary W. Grube, Barrington Hills, IL, Timothy W. Markison, Mesa, AZ, Jason K. Resch, Ilya Volvovski, and Manish Motwani, Chicago, IL.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method begins by a processing module monitoring a reprovisioned memory device that has been reprovisioned from a legacy storage protocol to an error coding dispersed storage protocol. The method continues with the processing module determining a data migration scheme for migrating a plurality of encoded data slices stored on the reprovisioned memory device and migrating the plurality of encoded data slices from the reprovisioned memory device to one or more other memory devices in accordance with the data migration scheme when a usable memory life of the reprovisioned memory device in the error coding dispersed storage protocol has expired.”

The patent application was filed on Aug. 5, 2011 (13/204,050).

Distributing multi-media content to a plurality of potential accessing devices
Cleversafe, Inc., Chicago, IL has been assigned a patent (8,762,479) developed by S. Christopher Gladwin, Chicago, IL, Gary W. Grube, Barrington Hills, IL, and Timothy W. Markison, Mesa, AZ, for “distributing multi-media content to a plurality of potential accessing devices.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method begins by a dispersed storage (DS) processing module encoding a data segment of multi-media content using a dispersed storage error coding function to produce a set of encoded data slices and partitioning the set of encoded data slices into a first sub-set of encoded data slices and a second sub-set of encoded data slices, wherein the first sub-set of encoded data slices include less than a decode threshold number of encoded data slices. The method continues with the DS processing module distributing the first sub-set of encoded data slices to a plurality of potential accessing devices and when accessing information from a device of the plurality of potential accessing devices is received, sending at least one of the encoded data slices of the second sub-set of encoded data slices to the device such that the device has the decode threshold number of encoded data slices.”

The patent application was filed on May 4, 2012 (13/464,166).

Dispersed storage of software
Cleversafe, Inc., Chicago, IL has been assigned a patent (8,762,343) developed by Gary W. Grube, Barrington Hills, IL, and Timothy W. Markison, Mesa, AZ, for a “dispersed storage of software.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A data de-duplication method begins by a processing module receiving a plurality of data storage requests from a plurality of requesting devices wherein a data storage request includes the data and a requester identifier (ID). The method continues with the processing module obtaining a data identifier (ID) for the data. For each of the plurality of data storage requests, the method continues with the processing module producing a requester storage record, dispersed storage error encoding the requester storage record to produce a set of encoded requester storage record slices, and sending the set of encoded requester storage record slices to a dispersed storage network (DSN) memory for storage therein. The method continues with the processing module dispersed storage error encoding at least a portion of the data to produce a set of encoded data slices and sending the set of encoded data slices to the DSN memory for storage therein.”

The patent application was filed on Oct. 12, 2010 (12/902,684).

Distributed storage network for storing data object based on storage requirements
Cleversafe, Inc., Chicago, IL has been assigned a patent (8,769,035) developed by five co-inventors for a “distributed storage network for storing a data object based on storage requirements.”

The co-inventors are Jason K. Resch, Chicago, IL, Wesley Leggette, Oak Park, IL, S. Christopher Gladwin, Greg Dhuse, and Andrew Baptist, Chicago, IL.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A distributed storage network (DSN) includes a user device and a plurality of DSN memories, wherein each of the DSN memories includes a plurality of storage units. The user device includes at least one network interface to the plurality of DSN memories and at least one processing module that is operable to determine one of the plurality of DSN memories for storing a data object based on a comparison of one or more storage requirements of the data object and one or more DSN attributes of the plurality of DSN memories.”

The patent application was filed on July 19, 2010 (12/839,181).
