The Classen Group gives notice to withdraw Patent cooperation with Välinge - The Classen group had previously, at Domotex in 2006, publicly presented the Classen Megaloc – an extremely successful vertical locking system for hard flooring. At Domotex in 2007 it was shown that from now on the complete collection of laminate flooring from the Classen Group has been changed to incorporate this simple and quick installation technique. Prior to the Domotex in 2007 the Classen Group had reached an agreement with another company offering a vertical locking system, Välinge AB (Sweden), which covered a joint marketing and licensing for various types of flooring products. From this Välinge should operate as licenser for both systems together on the market. Upon completion of the Domotex and the valuation of the response from trade visitors regarding the competitive fold down systems, Classen Megaloc and the Välinge 5G, it was ascertained that the overwhelming popularity of Classen Megaloc and the irreconcilable conceptual differences in the marketing approach made it necessary to terminate the previously reached agreement.
