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.

     United States Supreme Court Vacates Circuit Court Decision in Integra
                     LifeSciences -- Merck KGaA Litigation

Reasonableness Test Offered by Integra as Controlling Standard Remains Intact

PLAINSBORO, N.J., June 13, 2005 - Integra LifeSciences Holdings Corporation
(Nasdaq: IART) today announced that the United States Supreme Court vacated the
June 2003 decision of the United States Court of Appeals for the Federal
Circuit, which had affirmed the finding 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 United States Supreme Court today 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 the
standard which Integra LifeSciences proposed at trial and which has been its
consistent position on the proper interpretation of ss.271(e)(1) throughout this
litigation.

The Supreme Court held, consistent with Integra's position throughout the
litigation, that pre-clinical experiments are not categorically excluded from
the scope of the exemption. The Supreme Court also agreed with Integra, and with
the Federal Circuit, that the exemption does not globally embrace all
experimental activity that at some point may lead to an FDA approval process.
The Supreme Court's opinion today emphasizes that the scope of the Section
271(e)(1) exemption is determined under a reasonableness test. Integra's
position that Merck's activities are not exempt under the reasonableness test,
which it urged as the controlling standard throughout the litigation, remains
intact.

The underlying lawsuit, which was filed in 1996, alleged that Merck KGaA and a
non-profit research institution under contract from Merck KGaA had infringed
various United States patents held by The Burnham Institute of San Diego that
have been licensed to Integra.

Those patents include No. 4,792,525, No. 4,879,237, No. 5,695,997, and No.
4,789,734, each in various ways relating to technology involving peptides
containing an arginine-glycine-aspartic acid (RGD) sequence or related cell
surface receptors.

Compounds containing the RGD sequence promote or inhibit cell adhesion by
binding receptors called integrins found on the surface of almost every cell in
the body.



"We look forward to a successful resolution of the case on remand before the
Federal Circuit," said John B. Henneman, III, Executive Vice President and Chief
Administrative Officer. "In any case, neither these patents nor this decision
implicates any product that we sell, and the outcome - whether favorable or
unfavorable - will not have any impact on our operations."
