Align Technology, Inc., a US-based company specializing in clear aligner orthodontic products, sought provisional measures, including a preliminary injunction, against various European subsidiaries of Angelalign Technology. Align accused these subsidiaries of infringing on its European Patent No. EP 4 295 806 B1, which relates to the design and use of orthodontic appliances for moving teeth. The patent was registered with unitary effect and has not faced opposition thus far. Align is known for its 'Invisalign G6' technology, while Angelalign markets similar products like the 'A7 Premolar Extraction Solution'. The court's decision addressed provisional measures and the burden of proof in the context of potential patent infringement.
