MCLEAN, Va., Sept. 14 /PRNewswire-FirstCall/ -- MicroStrategy(R) Incorporated , a leading worldwide provider of business intelligence software, today announced that it has won an appellate court decision affirming the dismissal of the sole remaining claim in a lawsuit brought by Business Objects, S.A. in October 2001 alleging that MicroStrategy infringed United States Patent No. 5,555,403, entitled "Relational Database Access System Using Semantically Dynamic Objects" ("the '403 patent") owned by Business Objects.

In a unanimous opinion issued September 13, 2006, the United States Court of Appeals for the Federal Circuit affirmed a 2005 summary judgment ruling of a federal district court in San Francisco that found that MicroStrategy's products use a "much more sophisticated approach to generating queries" than the invention claimed by Business Objects, and that the consequence of this greater sophistication is that MicroStrategy's products have "greater and improved functionality" and generate "faster and more efficient queries" than Business Objects' system. The Federal Circuit affirmed the district court's holding that MicroStrategy's products do not infringe the '403 patent as a result of these "numerous," "important," and "substantial" differences, and affirmed the district court's dismissal of Business Objects' lawsuit, which sought injunctive relief and damages in excess of $100 million, with prejudice. The Federal Circuit is located in Washington, D.C., and is the appellate court that hears all patent cases in the United States.

"This is a great victory for MicroStrategy and its customers, employees, and shareholders," said Jonathan F. Klein, MicroStrategy's Vice President, Law & General Counsel. "We have invested many millions of dollars to develop and deliver the industry's most advanced and scalable business intelligence solutions. The Federal Circuit's ruling confirms the substantial differences between MicroStrategy's enterprise-class technology and the basic ideas embodied in Business Objects' products and '403 patent filed more than a decade ago," continued Klein.
