Mentor Announces Favorable Court Decision

Apr 17, 2001, 01:00 ET from Mentor Corporation

    SANTA BARBARA, Calif., April 17 /PRNewswire/ -- Mentor Corporation
 (Nasdaq:   MNTR) today announced that the United States Court of Appeals for the
 Federal Circuit Court issued a decision reversing the trial court's entry of
 judgment which was in favor of defendants in an action brought by Mentor
 against Medical Device Alliance, Inc., its subsidiary, LySonix, Inc., and
 Misonix, Inc. for violation of Mentor's U.S. Patent No. 4,886,491.
     Mentor's patent relates to a method for ultrasonic-assisted liposuction.
 Mentor had filed suit for patent infringement in the U. S. District Court for
 the Central District of California.  Early in 1999, following a jury verdict
 in favor of Mentor for direct, contributory, and inducement of infringement of
 Mentor's patent by Medical Device Alliance, Inc., LySonix, Inc., and Misonix,
 Inc., the trial judge granted judgment in favor of the defendants, despite the
 jury's verdict.
     Mentor challenged the trial judge's ruling on appeal.  The Appeals Court
 has now ruled in favor of Mentor, upholding the jury's verdict of infringement
 that awarded Mentor with damages in excess of $5 million.
 
     Mentor Corporation develops and manufactures specialized medical products,
 which it markets throughout the world.  This release contains, in addition to
 historical information, forward-looking statements.  Such statements are based
 on management's current expectations and are subject to a number of
 uncertainties and risks that could cause actual results to differ materially
 from those described in the forward-looking statements.  Factors that may
 cause such a difference include, but are not limited to, those described in
 the Company's Annual Report on Form 10-K for the fiscal year ended March 31,
 2000.
