Permabit Awarded Three Patents

Permabit Technology Corporation has been awarded three new patents by the US Patent and Trademark Office. These patents cover a broad range of data deduplication, retention and security within cloud storage environments.

Highlights include:

• U.S. Patent No. 7,496,555 covers the use of a data fingerprint (such as a cryptographic hash) so that an application server can access a data item from a nearby data repository instead of a client sending it over a lower speed link, and managing content retention of data in that repository.
• U.S. Patent No. 7,506,173 covers mechanisms to prevent unauthorized data sharing by fingerprint, such as deduplication or content-address storage (CAS), in a content repository.
• U.S. Patent No. 7,587,617 covers the use of a storage client where data to be stored that is found to already exist in a public repository, identified by content fingerprint, is stored by reference in that public repository, but unique data is stored in a separate private repository.

These new patents continue to build upon Permabit’s already extensive storage patent portfolio, including the use of hash-based deduplication for scalable file and object data storage, Permabit’s unique encrypted deduplication, snapshotting, and many other features of the company’s Scalable Data Reduction (SDR) technology which are the foundation of its Dedupe 2.0 strategy. With these, Permabit has a total of 16 patents covering diverse areas in data deduplication, protection and archive, and many more filings are pending in similar areas.

Permabit showed its patented technology at its booth and during two presentations at the SNW Fall 2009 conference.

"Permabit continues to secure critical patents in the areas of advanced deduplication and technologies optimized for cloud storage environments. The awards of these recent patents continue to prove that our vision that began in 2000 of a massively scalable, reliable, and secure storage platform for both internal use and for service providers is one hundred percent on target," said Jered Floyd, Chief Technology Officer, Permabit.
