IPG Photonics Corporation reported that the Local Division of the Unified Patent Court in Mannheim, Germany ruled that certain designs of its adjustable mode beam (AMB) lasers used in welding and cutting applications infringe European Patent 2,951,625 held by Trumpf SE & Co. KG.
The decision affects specific AMB laser products sold in seven UPC member states, including Germany, France and Italy, and the company states these products represent less than 1% of its total sales. Remedies for the patent owner, such as an injunction, recall and damages, will be determined later after required conditions are met. IPG is implementing contingency measures to support AMB customers, notes that its other lasers were not involved, and plans to appeal the ruling to the UPC Court of Appeal.
