The patent is valid for the U.S. market where Pergo has a leading market position. Sales in the U.S. marketplace constitute about two-thirds of the company's total, Pergo said.

The company characterized its new patent as a pioneer patent encompassing breakthrough technology in its field. The patent is for tight glueless joints milled into a wood-based carrier. This latest patent is broader than patents earlier issued to Pergo and it is expected to give the company a competitive advantage in the U.S. market.
