Exhibit 99.1


             Immersion Obtains $90.7 Million Judgment in
                Patent Infringement Case Against Sony


    SAN JOSE, Calif.--(BUSINESS WIRE)--March 28, 2005--Immersion
Corporation, (Nasdaq:IMMR), a leading developer and licensor of touch
feedback technology, today announced that the U.S. District Court for
the Northern District of California entered judgment in its favor in
its patent infringement suit against Sony Computer Entertainment, Inc.
and Sony Computer Entertainment of America, Inc. (Sony). On September
21, 2004, the jury returned a verdict favorable to Immersion and
awarded past damages in the amount of $82.0 million based on sales of
infringing products through June 30, 2004. The Court's judgment on
March 24, 2005 awarded Immersion the $82.0 million in past damages,
plus pre-judgment interest in the amount of $8.7 million, for a total
of $90.7 million.
    The Court also issued a permanent injunction against the
manufacture, use, sale, or import into the United States of the
infringing Sony PlayStation system including PlayStation consoles,
Dual Shock controllers, and the 47 games found by the jury to infringe
Immersion's patents. The Court stayed the permanent injunction pending
appeal to the United States Court of Appeals for the Federal Circuit.
The Court further ordered Sony to pay a compulsory license fee for the
duration of the stay of the permanent injunction at the same rate and
conditions as previously awarded in its January 10, 2005 and February
9, 2005 Orders. Sony made a payment to Immersion pursuant to those
Orders on February 15, 2005 for the July 1, 2004 through December 31,
2004 period; however, Sony has appealed these Orders.
    The Court also found in favor of Immersion on Sony's allegations
of inequitable conduct during the prosecution of one of the patents
asserted against Sony. In a matter related to the Sony lawsuit, the
Court entered an order dismissing certain of the claims brought by
Internet Services LLC (ISLLC) against Immersion with prejudice and
certain claims without prejudice.
    Immersion expects that Sony will appeal the judgment to the United
States Court of Appeals for the Federal Circuit. Sony also may post a
bond with the Court to stay the obligation to immediately pay the
amount of the judgment while appeals are pending.
    "The Court's entry of judgment implements last September's jury
verdict and the damages award," said Immersion CEO Victor Viegas. "The
Court-ordered permanent injunction to stop the shipment and sale of
infringing products in the U.S. is an important indicator of the
strength of our case and the potential risks involved in this
litigation. The compulsory license during the stay of the injunction
creates a binding obligation for Sony to compensate us for the
continued use of our technology in their PlayStation products. We have
always believed, and continue to believe, in the strength of our
intellectual property. We remain confident of our position in the
appeals process.
    "Immersion is built on a strong foundation of innovative
technology and intellectual property. We now hold more than 270
patents in our worldwide intellectual property portfolio and have more
than 280 patent applications pending. Immersion has a long list of
licensees in the automotive, gaming, medical, mobility, and other
markets, and we will continue to license our technology under
appropriate circumstances. We will also continue to vigorously defend
our intellectual property for the benefit of our licensees and
shareholders," concluded Viegas.
