NEW YORK The U.S. Court
of Appeals has upheld its December decision confirming
ArcelorMittal SAs patent on aluminum-precoated hot- or
cold-rolled steel for hot stamping, branded as Usibor, a
spokeswoman for the steelmaker said March 21 via e-mail.
"As interpreted by the court,
ArcelorMittals U.S. patent covers most of the steel U.S.
carmakers specify for hot-stamped parts," the spokeswoman said.
"Based on the decision, ArcelorMittal intends to enforce its
rights against any infringers."
In February, the U.S. Patent and Trademark Office announced
plans to reissue Luxembourg-based ArcelorMittals patent
for Usibor, which is produced for U.S. consumers at the
companys Indiana steelmaking facilities (
