Court Upholds Integra LifeSciences Patents

Finding of Infringement by Merck KGaA upheld; Case Remanded For New Damages
Calculation


Plainsboro, NJ /June 9, 2003 / -- Integra LifeSciences Holdings Corporation
(Nasdaq: IART) today announced that the United States Court of Appeals for the
Federal Circuit, ruling in the case Integra LifeSciences (et. al.) vs. Merck
KGaA, et. al., has affirmed the finding of the trial court that Merck KGaA
infringed four of Integra's licensed patents. The patents at issue relate in
various ways 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.

The order of the Federal Circuit relates to an appeal taken from a judgment of
the United States District Court for the Southern District of California entered
on September 29, 2000. That judgment confirmed a jury award to Integra and the
other plaintiffs of $15,000,000 in damages, plus interest. The Federal Circuit
decision also held that the basis of the jury's calculation of damages was not
clear from the trial record, and remanded the case to the trial court for
further factual development and a new calculation of damages consistent with the
Federal Circuit's decision.

The 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 RGD technology.

Since 1996, 28 patents relating to the RGD technology, all licensed exclusively
by Integra, have issued to The Burnham Institute. Among these, Integra believes
that US Patents 6,020,460, 5,985,827, 5,981,468, 5,906,975, 5,880,092,
5,994,501, and 5,916,875 are particularly significant.

"We are extremely pleased that the Court of Appeals upheld the finding of the
trial court that Merck KGaA infringed our patents," said John B. Henneman, III,
Executive Vice President and Chief Administrative Officer. "While Integra always
prefers to license technology and to collaborate with strategic partners rather
than to litigate over patents, we look forward to proving our damages in
accordance with the findings of the Federal Circuit."
