Cohesity Assigned Six Patents

Scalable deduplication
Cohesity Inc., San Jose, CA, has been assigned a patent (12271357) developed by Yang; Yong, Beijing, China, Zhang; Xianbo, Plymouth, MN, Wu; Weibao, Vadnais Heights, MN, Lei; Chao, Wang; Yafeng, Beijing, China, Wang; Haigang, Shoreview, MN, and Wei; Lulu, Beijing, China, for “methods and systems for scalable deduplication.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Methods, computer program products, computer systems, and the like are disclosed that provide for scalable deduplication. Such methods, computer program products, and computer systems can include, in response to receiving a request to perform a lookup operation, performing the lookup operation and, in response to the signature not being found, forwarding the request to a remote node. Further, in response to receiving an indication that the signature was not found at the remote node, processing the subunit of data as a unique subunit of data.”

The patent application was filed on 2023-07-05 (18/347395).

Managing expiration times of archived objects
Cohesity Inc., San Jose, CA, has been assigned a patent (12271340) developed by Van Dyck; Dane, Atlanta, GA, and Yarlagadda; Praveen Kumar, Santa Clara, CA, for “managing expiration times of archived objects.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “One or more objects associated with a source storage is determined to be archived to a remote storage. A corresponding minimum expiration time is stored in nodes of a tree data structure associated with an archive that represents the archived data associated with the source storage. At least a portion of the tree data structure associated with the archive is traversed to identify one or more nodes associated with one or more archived objects having a corresponding expiration time expiring before an expiration time associated with the archive.”

The patent application was filed on 2022-02-25 (17/681439).

Data resynchronization in replication environment
Cohesity Inc., San Jose, CA, has been assigned a patent (12265457) developed by Patil; Rushikesh, and Hasbe; Sunil, Maharashtra, India, for “methods and systems for data resynchronization in a replication environment.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Methods, computer program products, computer systems, and the like are disclosed that provide for scalable deduplication in an efficient and effective manner. For example, such methods, computer program products, and computer systems can include determining whether a source data store and a replicated data store are unsynchronized and, in response to a determination that the source data store and the replicated data store are unsynchronized, performing a resynchronization operation. The source data stored in the source data store is replicated to replicated data in the replicated data store. The resynchronization operation resynchronizes the source data and the replicated data.”

The patent application was filed on 2022-12-20 (18/068774).

Adaptive deduplication of data chunks
Cohesity Inc., San Jose, CA, has been assigned a patent (12265503) developed by Shankar; Aiswarya Bhavani, San Jose, CA, and Van Dyck; Dane, Atlanta, GA, Guturi; Venkata Ranga Radhanikanth, San Jose, CA, and Arulraj; Leo Prasath, Santa Clara, CA, for an “adaptive deduplication of data chunks.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Techniques are described for selectively extending a WORM lock expiration time for a chunkfile. An example method comprises identifying, by a data platform implemented by a computing system, a chunkfile that includes a chunk that matches data for an object of a file system; determining, by the data platform after identifying the chunkfile, whether to deduplicate the data for the object of the file system by adding a reference to the matching chunk, wherein determining whether to deduplicate the data comprises applying a policy to at least one of a property of the chunkfile or properties of one or more of a plurality of chunks included in the chunkfile; and in response to determining to not deduplicate the data for the object of the file system, causing a new chunk for the data for the object of the file system to be stored in a different, second chunkfile.”

The patent application was filed on 2023-03-14 (18/183659).

Maintaining and updating backup view of application and its associated objects
Cohesity Inc., San Jose, CA, has been assigned a patent (12242353) developed by Lee; Steve Tai Hung, Lexington, MA, for “maintaining and updating a backup view of an application and its associated objects.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A first backup of source data is performed. A second backup of the source data is determined to be performed at least in part by determining a plurality of objects that have changed since the first backup and determining a corresponding backup type for each of the plurality of objects that have changed since the first backup. Based on the determined corresponding backup types, a second backup of the source data is performed including by performing an incremental backup of a first portion of the plurality of objects that have changed since the first backup and a full backup of a second portion of the plurality of objects that have changed since the first backup.”

The patent application was filed on 2022-10-05 (17/960515).

Sorted entropy chunks for higher space reduction
Cohesity Inc., San Jose, CA, has been assigned a patent (12197389) developed by Singh; Sweetesh, New Delhi, India, for “sorted entropy chunks for higher space reduction.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Techniques are described for creating more efficient chunkfiles through the use of entropy metrics. In some examples, processing circuitry may determine an entropy value for each of a plurality of data chunks to obtain a corresponding plurality of entropy values. In some examples, processing circuitry may reorganize, based on the corresponding plurality of entropy values, the plurality of data chunks to obtain a reorganized plurality of data chunks. In some examples, processing circuitry may compress the reorganized plurality of data chunks to obtain a compressed chunkfile. In some examples, processing circuitry may store the compressed chunkfile superseding the plurality of data chunks.”

The patent application was filed on 2023-10-30 (18/497635).
