On the 6th of June 2006, the Canadian Patent Office has granted the so-called clearances patent to Unilin. The patent has been issued as CA 2,475,076. The patent protects a wide range of glueless joint systems for wood-based flooring panels and claims a priority date in 1996. In August of 2005 the United States Patent Office already issued the American counterpart of this clearances patent as US 6,928,779 and in October of the same year the European Patent Office has granted the European counterpart as EP 1 223 267.

With this newly granted patent CA 2,475,076 Unilin significantly extends its intellectual property rights in Canada in the field of glueless flooring panels. This patent is considered a valuable additional tool for Unilin to enforce the respect for its developments in this field.
