In this case, Dyson Technology Limited appealed a decision by the Hamburg Local Division of the Unified Patent Court concerning a preliminary injunction related to patent infringement. Dyson holds European Patent 3 119 235 for a handheld hair care device and claimed that Dreame International and affiliates infringed this patent with their products. The Court of First Instance issued an injunction, finding the Old Dreame Products likely infringed the patent, but not the New Dreame Products. Dyson sought to extend the injunction to cover these new products, while Dreame sought to have the injunction removed completely. The Court of Appeal decided on procedural issues, including partially staying the appeal proceedings.
