Cohesity Assigned Five Patents

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).

Container-based erasure coding
Cohesity, Inc., San Jose, CA, has been assigned a patent (12164477) developed by Gupta; Apurv, Bengaluru, India, Agarwal; Akshat, Delhi, India, Tomar; Manvendra Singh, Madhya Pradesh, India, Reddy; Donthula Akshith, Bheemaram, India, Singh; Kushal, Bengaluru, India, Yadav; Tarun Kumar, Rajasthan, India, and Naik; Mandar Suresh, Pune, India, for a “container-based erasure coding.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A repository of replicated chunk files is analyzed to identify chunk files that meet at least a portion of combination criteria. Selected chunk files are associated together under a data protection grouping container. Erasure coding is applied to the data protection grouping container including by utilizing the selected chunk files as different data stripes of the erasure coding and generating one or more parity stripes based on the different data stripes.”

The patent application was filed on 2022-01-24 (17/582763).

Extending expiration time of object associated with archive
Cohesity, Inc., San Jose, CA, has been assigned a patent (12158859) developed by Van Dyck; Dane, Atlanta, GA, and Yarlagadda; Praveen Kumar, Santa Clara, CA, for “extending an expiration time of an object associated with an archive.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An amount of expiration time extension for one or more objects associated with a first archive of a first snapshot of a source storage is determined based at least in part on a second data management policy associated with a second archive and one or more dynamically determined metrics. The first archive that includes the one or more objects is caused to be stored to a remote storage. At least a portion of content of the first archive is referenced by data chunks stored in a first chunk object of the remote storage and the first archive is associated with a first data management policy. Based on the determined amount of expiration time extension, an expiration time for the one or more objects associated with the first archive is stored in an archive metadata of the one or more objects associated with the first archive.”

The patent application was filed on 2022-01-31 (17/589116).

Utilizing progress identifiers to rewrite event query
Cohesity, Inc., San Jose, CA, has been assigned a patent (12141271) developed by Chakankar; Abhijit, San Jose, CA, Gupta; Pramesh, Rajnandgaon, India, Vishvkarma; Vipin, and Gupta; Apurv, Bangalore, India, for “utilizing progress identifiers to rewrite an event query.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Events from one or more primary systems associated with one or more tenants are received. The received events are stored in a message queue. At least a portion of the events in the message queue are ingested for organization and storage in a data store. One or more progress identifiers associated with ingesting of the events in the message queue are tracked. An event query is received from an external system. The event query is rewritten into a first component query for the data store and a second component query for the message queue based at least in part on a progress identifier. A result of the first component query and a result of the second component query are combined to determine a result of the event query.”

The patent application was filed on 2021-07-27 (17/386076).
