Circadence Strengthens its Intellectual Property Portfolio in the WAN Optimization Field with Newly Issued Patent

Distributed Database Services Patent is the Fourth Issued Patent for the Company in 2006

BOULDER, Colorado, September 25 – Circadence Corporation, an industry-leading provider of wide area network (WAN) optimization technology to the US Government and commercial enterprise, today announced that it is was awarded another new patent by the United States Patent and Trademark Office. The Company was issued U.S. Patent No. 7,111,006, "System and Method for Providing Distributed Database Services." This is the eighth patent that has been awarded to Circadence and the Company's fourth patent to issue this year. The patent addresses a broad range of distributed database applications across wide area networks and explicitly covers such uses as database queries, database management traffic, remote procedure calls and any query/response traffic that ultimately relies on a data store. When coupled with Circadence's U.S. Patent No. 6,990,531, "System and Method for Providing Last-Mile Prioritization," which was issued earlier this year and covers Quality of Service (QOS) responsive regulation of traffic flow, it provides the Company with powerful intellectual property support for its WAN optimization technology, products and services.

"WAN optimization is becoming increasing vital as enterprises shift more of their business functions to a netcentric model," said Michael J. Moniz, Chief Executive Officer of Circadence. "This patent dramatically enhances and expands the boundaries of our already formidable intellectual property portfolio in the WAN optimization field and provides us with a uniquely competitive position."

About the Issued Patent

U.S. Patent No. 7,111,006, "System and Method for and System for Providing Distributed Database Services."

This patent describes a database system operating over a communication network where client applications that are coupled to the network generate database access requests. An intermediary server that is also coupled to the network receives the requests and a data storage mechanism coupled to the network has an interface for communicating with the intermediary servers. The intermediary server is responsive to a received client database access request and establishes a channel with the data storage mechanism to obtain data from such mechanism. The intermediary server can also format the obtained data in a manner suitable for use by the client application that requested the associated database access.

"We are pleased to have been granted this key patent, which covers a host distributed delivery applications across wide area networks," said Mark Vange, Chief Technology Officer of Circadence and an inventor on the patent. "This patent covers the provisioning of distributed database services not only for direct database accesses, but also for applications that rely on database access such as Microsoft Outlook/Exchange or Lotus Domino. It also covers web applications that retrieve information across the web, such as many banking, travel, financial services and other data-driven websites."
