Hyperion Denies Wrongdoing, Will Vigorously Defend Itself Against Clai

    Business Editors/High-Tech Writers

    SANTA CLARA, Calif.--(BUSINESS WIRE)--Jan. 19, 2005--Hyperion (Nasdaq:HYSL), the global leader in Business Performance Management software, has announced that it will vigorously defend itself against all patent infringement and other claims made by HyperRoll in a lawsuit filed in U.S. District Court on January 18, 2005. Hyperion said it has not infringed nor misappropriated any of HyperRoll's patents or other intellectual property.
    HyperRoll's lawsuit follows statements it made to Hyperion last year in which it threatened to sue Hyperion for patent infringement. Proactively responding to those threats, Hyperion filed a declaratory judgment action in Federal District Court for the Northern District of California against HyperRoll on November 30, 2004. Hyperion's declaratory judgment action will establish that Hyperion has not infringed any of HyperRoll's patents.
    "Based on our review of HyperRoll's allegations, our team believes that HyperRoll's claims are without merit," said Godfrey R. Sullivan, Hyperion's president and chief executive officer. "We are committed to protecting our own intellectual property and maximizing the benefits of our technology for our customers, partners, and shareholders. We will vigorously defend ourselves."
