Exhibit 99.1

Itron Settles Patent Infringement Litigation

    SPOKANE, Wash.--(BUSINESS WIRE)--Oct. 15, 2003--Itron, Inc.
(Nasdaq:ITRI) announced today that it has entered into a settlement
agreement with Ralph Benghiat, an individual, that resolves all
outstanding Benghiat patent litigation issues and assigns ownership of
Mr. Benghiat's patent to Itron.
    On December 20, 2002, a jury in Minneapolis found that Itron's
manual entry handheld meter reading devices infringed a patent owned
by Mr. Benghiat and awarded Mr. Benghiat damages of $7.4 million. On
August 29, 2003, the Court issued an injunction prohibiting sales of
the accused products and awarded Benghiat interest on the verdict,
which Itron estimated to be approximately $2 million.
    According to the terms of the settlement, Itron will pay Benghiat
$7.9 million to settle all payments to Benghiat for royalties,
interest, attorney's fees and any other items. The agreement also
specifies that ownership of the patent will be transferred to Itron.
Itron had previously recorded a $7.4 million pre-tax charge for the
amount of the jury's award in December 2002 and will record an
additional $500,000 charge in the third quarter of 2003.
    "While we continue to believe that our products do not infringe
the Benghiat patent, this settlement will allow us to focus our
efforts and resources in a positive direction for our customers,
employees and shareholders," said LeRoy Nosbaum, chairman and CEO of
Itron.
