IPG Photonics announced that the Local Division of the Unified Patent Court located in Mannheim, Germany has issued a decision in a patent infringement case brought by Trumpf SE & Co. KG. The court ruled that certain designs of IPG's adjustable mode beam lasers used in welding and cutting applications infringed European Patent 2,951,625. The decision impacts certain AMB laser products sold in seven UPC contracting member states, including Germany, France and Italy, affecting less than 1% of IPG's total sales. IPG respectfully disagrees with the decision and plans to file an appeal with the UPC Court of Appeal.
