摘要

Arcelor, the world's second-largest steel maker, said on Thursday it had begun legal action in the United States against its unsolicited bidder Mittal Steel, alleging patent infringement. "The suit was filed Tuesday in the United States," Arcelor spokesman Luc Sheer said on Thursday, clarifying an earlier statement from the company on Luxembourg press reports. Another Arcelor spokesman, Jean Lasar, said the lawsuit concerned so-called Usibor steel technology, used in the automobile industry.
