TOLLAND, CONN. AND SAN MATEO, CALIF. – March 23, 2005 – Nerac, a leading information resource for scientists, engineers and Intellectual Property (IP) professionals, today announced that it has selected Mark Logic Corporation, provider of the industry's leading XML content server, to implement a smart content management system and develop a real-time patent search platform for its end-user customers. These streamlined Web-based solutions, combined with a research staff of scientists and engineers, will launch Nerac into the next generation of high-level information services.

"Mark Logic's XML content server will provide Nerac with the right technology to enhance the knowledge power of Nerac's scientists and engineers," said Kevin Bouley, Nerac President. "With Mark Logic, our unique business model of uncovering mission critical information through client collaboration will now provide Nerac with the tools to become a more highly focused player in an already competitive marketplace."

California-based Mark Logic Corporation is working closely with Nerac's programming team to develop the content integration and patent search platform. As a leading provider of XML content platforms for the information industry, Mark Logic will help build a powerful new search platform for Nerac's Information Specialists, a research staff of more than 100 scientists and engineers. This back-end platform will allow Information Specialists to research multiple and different data formats simultaneously from a variety of disparate resources.

Using its robust XML content platform based on the W3C-standard XQuery language, Mark Logic works with providers of information products like Nerac to accelerate new product creation, deliver products through multiple channels, integrate content from different sources, repurpose content into multiple products, build custom publishing systems and mine content to find previously undiscovered information.

The new Mark Logic-based system will greatly improve Nerac's service offerings and help Information Specialists deliver research that combines expert commentary with database information, Internet references and various additional resources all into one organized report. New features for Nerac users include highlighted key terms, document attachments and advanced sorting and display options within the research reports.

Additionally, clients will be able to use Nerac's customer Website to conduct real-time searching on full-text patent files. This functionality will add to Nerac's current capabilities, which allow users to download full-image patents. Additional details on the new patent search capabilities will be released within the upcoming months.

"Nerac joins a growing number of companies in the information industry using Mark Logic as the foundation to provide innovative new products and services to its customers. Through our close collaboration with Nerac's programmers and designers, Mark Logic is convinced that our XML content server will help propel its services to the next level," said Dave Kellogg, president and chief executive officer of Mark Logic Corporation.
