             Itron Issues Update on Patent Infringement Litigation;
                Court Issues Order Ruling on Post-Trial Motions

     SPOKANE, Wash.--(BUSINESS WIRE)--Sept. 3, 2003--Itron, Inc. (Nasdaq:ITRI)
today reported that the United States District Court, District of Minnesota, has
issued an Order addressing post-trial motions in the Benghiat patent litigation.
     In December 2002, a jury in Minneapolis returned a verdict against Itron
and found that Itron's manual entry handheld meter reading devices infringed a
patent owned by Ralph Benghiat, an individual. The jury awarded Benghiat damages
of $7.4 million and determined that Itron's infringement was willful.
     In July 2003, a number of post-trial motions were filed by both parties.
Benghiat moved for interest on the verdict, the prohibition of infringing
product sales, and an accounting of royalty bearing sales by Itron from July 1,
2002 through December 20, 2002, the date of the verdict. Itron opposed
Benghiat's motions and filed other motions.
     Under the Court's Order dated August 29, 2003, the Court denied all of
Itron's motions and granted Benghiat's motions for an injunction on infringing
product sales, interest on the verdict and an accounting of royalty bearing
sales.
     Although Itron continues to believe that its products do not infringe the
Benghiat patent, in early 2003, it redesigned the products that were found to
infringe Benghiat's patent and have received an opinion from outside counsel
that the redesigned products do not infringe the patent. This means that Itron's
customers will continue to be able to purchase and use its handheld products
despite the ruling by the Court to enjoin sales of the infringing products.
     Itron recorded a $7.4 million pre-tax charge for the amount of the jury's
award in December 2002. No accrual has been made for prejudgment interest, which
Itron estimates to be approximately $2 million.
     Appeals of the Court's final judgment must be made within 30 days to the
Federal Circuit Court of Appeals in Washington D.C. Itron intends to file such
an appeal within the next few days. Payment of the final judgment award plus
accrued interest, after the posting of an appropriate bond, would not be due
until any appeals have run their course, which Itron estimates would take
approximately 18 to 24 months.
