Hologic Secures Significant Patent Victory Against Siemens Over Breast Cancer Detection Technology

Court orders Siemens to halt production and recall and destroy products across Germany, France and the Netherlands

Hologic, Inc. today announced a significant and far-reaching victory in the Unified Patent Court (UPC) in Germany, which ruled that Siemens* infringed upon a critical Hologic mammography technology patent in Siemens’ latest mammography system. The court imposed a sweeping injunction, immediately prohibiting Siemens from making, offering, placing on the market, using or importing or storing for those purposes its MAMMOMAT B.brilliant systems across Germany, France and the Netherlands, as well as monetary damages and penalties for non-compliance. The court also required Siemens to execute a mandatory recall and destruction of all affected systems in those countries.

On June 10, 2026, the UPC determined that Siemens infringed upon European Patent EP 2 352 431, Hologic’s Focusing Technology on the Envision™ Platform, the first FDA-approved mammography innovation of its kind.¹

In addition to the broad injunction against Siemens, recall and destruction of infringing systems, Hologic will receive retroactive and future damages and costs to be determined by the Court. Siemens must also refund customers of the infringing systems for the purchase price paid and reimburse them for logistics and related costs as part of the recall.

“This ruling is a decisive validation of the strength and originality of Hologic’s innovation —and, more importantly, of the standards we believe women deserve in breast cancer screening,” said Essex Mitchell, Chief Operating Officer at Hologic. “Our technologies are designed to help detect cancer earlier, improve diagnostic confidence and ultimately save lives. When other companies infringe on our patented inventions, it risks undermining the development of new and innovative products that give physicians the ability to deliver the care patients depend on. Hologic will continue to work to ensure clinicians have access to the most advanced, proven technologies and that women worldwide have access to the latest screening innovations.”
