ITEM 8.01.  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.
