Transtex LLC and Transtex Composite Inc. (together Transtex) announced it has filed a patent infringement lawsuit against WABCO Holdings and Laydon Composites in the U.S. District Court for the Eastern District of Texas, Marshall Division on June 30.

In the lawsuit, Transtex claims WABCO Holdings and Laydon Composites infringe eight of Transtex's patents by manufacturing and selling infringing trailer skirts under the trade name TrailerSkirt (Models TS225, TS248 and TS259). The patents-in-suit are listed below and concern Transtex's aerodynamic solutions and methods for designing and manufacturing trailer side skirts: United States Patent Numbers - 7,748,772, 7,887,120, 7,942,467, 7,942,469, 7,942,471, 8,292,351, 8,449,017, and 8,678,474.

"At Transtex, we stand behind our products," said Mathieu Boivin, CEO and president. "We invest heavily in research and development to ensure our customers continue to receive the most innovative product offerings."

In December 2012, Transtex stated it favorably settled a declaratory judgment action for patent infringement with competitor Ridge Corporation, which manufactures and sells side skirts under the name "Green Wing." That action was Case No. 2:11-cv-00840 in the U.S. District Court for the Southern District of Ohio, Eastern Division.

"Just as we have done in the past with other competitors, we will continue to take proactive measures to protect our brand and intellectual property," Boivin said.
