Context: Nixu FL IP Protection, a SIM IP subsidiary, has been actively enforcing patents acquired from FusionLayer’s cloud networking portfolio. The portfolio, acquired in April 2025, comprises more than 30 patent assets covering cloud-native automation, DNS security, software-defined IP address management, and dynamic network provisioning. Earlier this year, Nixu FL filed a UPC infringement action against Infoblox over a different patent from the same portfolio, marking the start of a broader European enforcement campaign (February 1, 2026 ip fray article).
What’s new: Nixu FL IP Protection has filed a patent infringement action before the UPC’s Milan Local Division (LD) against Amazon Web Services (AWS), AWS EMEA, AWS European Sovereign Cloud GmbH, and Amazon Data Services Italy. The plaintiff asserts European patent EP3417570, which relates to cloud networking technology, and seeks pan-UPC relief, including injunctive relief, damages, and other remedies available under the UPC Agreement (UPCA).
Direct impact: The filing brings one of the world’s largest cloud service providers before the UPC while extending Nixu FL’s European enforcement campaign. It also adds another software and cloud infrastructure dispute to the UPC’s growing docket, illustrating the court’s expanding role beyond its early concentration on life sciences and telecommunications.
Wider ramifications: The AWS action demonstrates how patent owners are using the UPC to implement portfolio-based enforcement strategies against multinational technology companies. It follows Nixu FL’s separate litigation against Infoblox involving another patent from the acquired FusionLayer portfolio, illustrating that the company’s enforcement efforts extend beyond a single patent.
According to SIM IP, the AWS case is part of a broader strategy to enforce patents acquired from FusionLayer’s cloud networking portfolio, with EP3417570 representing just one of several related patents.
