IPG Photonics Corporation (NASDAQ: IPGP) announced that the Unified Patent Court in Düsseldorf, Germany ruled against the company in a patent infringement case brought by Trumpf SE & Co. KG.

The court determined that certain uses and designs of IPG's adjustable mode beam lasers infringed European Patent 2,624,031. The decision affects AMB laser products sold in Germany, France and Italy, impacting less than 1% of IPG's total sales.

The company stated it is implementing contingency measures to support AMB customers and noted that other laser models were not involved in the lawsuit. IPG's broader product portfolio remains available for sale.

Remedies available to the patent owner, including an injunction, recall and damages, may be enforced at a later time after required conditions are satisfied. IPG plans to file an appeal with the UPC Court of Appeal and pursue other available measures.

This represents the second patent ruling against IPG's AMB lasers. The company previously disclosed that Trumpf affiliates brought separate actions in Unified Patent Courts in Mannheim and Düsseldorf asserting different patents. IPG had previously announced the Mannheim court's decision and its intention to appeal that ruling as well.

The information was disclosed in a company press release statement issued March 16.
