Vignette Continues Its Rich Heritage of Innovation; Software Company Awarded Its Second and Third Patents of 2005.

AUSTIN, Texas -- Vignette Corp. (Nasdaq:VIGN) today announced it has been awarded patents for technologies that help its customers easily and effectively access information and interact with files regardless of the operating system.

Automatic Query and Transformative Process Technology

The U.S. Patent and Trademark Office granted U.S. Patent No. 6,882,995, entitled Automatic Query and Transformative Process, to Vignette for its unique method of retrieving information in a markup language through a query engine and presenting the information in any targeted markup language. The technology transforms myriad of markup languages into the markup language of choice based on the structure of the query. Without the innovation, existing query engines do not support the transformation of markup languages based upon the query.

Vignette's patented technology provides users with the ability to access information quickly and in a format with which they are familiar. For instance, the innovation allows a user to execute a browser search via search via Hypertext Transfer Protocol (HTTP), the query may locate the relevant information in an XML-encoded compound document, and the innovation will then transform that information back into HTML for presentation. Given that businesses today have information stored in myriad of file and programming languages, the technology supports file, programming and other presentation formats beyond HTML and XML such as Wireless Markup Language (WML).

By applying this technology, organizations can dynamically generate content in the appropriate language and format across collections of documents regardless of document type, creating a better experience for employees, customers and partners, which in turn translates to enhanced decision support and customer satisfaction and loyalty.

Platform-Independent File System Interaction

The U.S. Patent and Trademark Office also granted U.S. Patent No. 6,892,377, entitled Method and System for Platform-Independent File System Interaction, to Vignette for its unique technology that provides an application developer the capability to interface with an operating system's file system in a seamless and transparent manner, regardless of the underlying operating system. Through a single programmatic interface, developers can access and manipulate file specifications, regardless of operating system locale or the nature of an original file encoding. This ability is especially relevant as more and more organizations standardize their global information management solutions.

"Vignette has a long tradition of driving technology innovation to help organizations leverage the power of information and the Web to drive business efficiency," said Conleth O'Connell, chief technology officer at Vignette. "Vignette continues to find inventive ways to impact the way in which information is managed and delivered to give people access to the information they need when they need it, so they can make informed decisions and deliver better business results."

Vignette cultivates an environment that is committed to breakthrough technology. The company currently holds several patents and has a number of patent applications pending in the United States.
