Huber Engineered Woods Patent Infringement Lawsuit Settled

CHARLOTTE, N.C. (August 7, 2023) – Specialty building products manufacturer Huber Engineered Woods LLC (“HEW”) has achieved a negotiated settlement with Louisiana-Pacific Corporation (“LP”) in the patent infringement lawsuit filed by HEW in the United States Court for the District of Delaware (Huber Engineered Woods LLC v. Louisiana-Pacific Corporation, Civil Action No. 1:19-cv-342).

The lawsuit, filed in February 2019 by the Charlotte-headquartered manufacturer, alleged that LP’s WeatherLogic® Air & Water Barrier products infringed HEW’s patents for its ZIP System® sheathing and tape products.

“For almost three decades, Huber Engineered Woods has provided innovative, premium products to our customers," said HEW President Brian Carlson. “Investing in the continued development and protection of our intellectual property portfolio is central to our company’s strategy and success. We have and always will be vigilant in the defense and protection of our brands and intellectual property.”

Since its introduction in 2006, ZIP System® sheathing and tape has been quickly and widely adopted as a replacement for traditional sheathing and housewrap. The innovative exterior wall and roof system consists of a high-performance engineered wood panel with a built-in, water-resistive barrier that eliminates the need for housewrap or felt. Completed with taped panel seams using advanced, acrylic-based ZIP System™ tape, the system helps achieve quick rough dry-in, while providing a continuous air barrier to protect against unwanted air leakage.
