OTHER EVENTS. On June 13, 2005, the United States Supreme Court vacated the June 2003 judgment of the United States Court of Appeals for the Federal Circuit, which had affirmed the judgment of the United States District Court for the Southern District of California in the case of Integra LifeSciences I Ltd. and The Burnham Institute v. Merck KGaA. The Supreme Court held that the Court of Appeals applied an erroneous interpretation of 35 U.S.C. ss.271(e)(1) when it rejected the challenge of Merck KGaA to the jury's finding that Merck KGaA failed to show that its activities were exempt from claims of patent infringement under that statute. On remand, the Federal Circuit will review the evidence under a reasonableness test that does not provide categorical exclusions of certain types of activities. As a result, the trial court's judgment ordering Merck KgaA to pay Integra $6.4 million in damages could be overturned. The Company has not recorded any gain in connection with this matter, pending final resolution and completion of the appeals process. A copy of the press release issued by the Company discussing the ruling is attached as Exhibit 99.1 to this Current Report on Form 8-K. ITEM 9.01. FINANCIAL STATEMENTS AND EXHIBITS. (c) Exhibits.
