ATN Holdings will infringe upon Quanex’s patents no more, according to a recent release put out by Quanex.

On November 6, 2014, a subsidiary of the Houston-based company filed a lawsuit against ATN Holdings of California for infringement of five patents related to spacer and sealant assemblies, specifically its Duraseal product line. On August 17, 2015, the lawsuit was dismissed.

ATN agreed to cease using and selling any product that violates Quanex’s patents.

“We consider this settlement a victory in protecting the decades of experience and technical expertise that Quanex offers to the marketplace,” says Kevin Delaney, senior vice president, general counsel and secretary for Quanex. “We are committed to protecting our patents and other intellectual property globally and we have a zero-tolerance policy for those who attempt to unlawfully duplicate our innovations.”

In addition, an Order of Dismissal with prejudice for the antitrust case ATN filed against Quanex was entered by the United States District Court, Central District of California. ATN also agreed to make a monetary payment to Quanex, which agreed to withdraw the motion for Rule 11 sanctions it had filed against ATN, according to the release.
