Permabit Awarded Five New Patents on Data Deduplication
and Archiving

Patent Portfolio for Scalable, Reliable, Long Term Data Storage Increases to 13 for Permabit Technology

CAMBRIDGE, Mass. — March 16, 2009 — Permabit Technology Corporation, the industry’s leading innovator of scalable, data–reduced storage for enterprise archiving, today announced it has been awarded five new patents by the US Patent and Trademark Office.  These patents cover a broad range of data retention capabilities. Highlights include:

• US Patent No. 7,478,096 broadly covers records retention in disk–based distributed storage systems.

• US Patent Nos. 7,457,800 and 7,457,813 describe and protect advances developed for Permabit’s internal file system that allow Permabit to deliver unprecedented performance and scalability in an in–line data deduplication system.  These patents exemplify Permabit’s technical expertise in deduplication and their advances beyond the competition.

• US Patent No. 7,457,959 covers verifiable digital timestamps in a storage system such that while a record is stored its contents and timestamp can be proven correct and unmodified, however after the record has been deleted it is not possible to determine the previous existence or content of the record.

• US Patent No. 7,467,144 protects the use of a deduplicated content repository for web and other network application acceleration purposes, such as in the rapidly growing field of WAN acceleration.

These new patents build upon Permabit’s already extensive 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.  With these Permabit has a total of 13 patents covering diverse areas in data protection and archive, and many more filings are pending in similar areas.
