Nautilus asserted three patents: US10518123B2 (application US14/304853), US7614982B2 (application US11/844565), and US8002680B2 (application US12/882018). All three relate to adjustable dumbbell systems. The case was filed on June 22, 2022 in the Central District of California.

The court entered a stay on June 14, 2023 based on a Joint Stipulation to Stay Case filed by the parties. The order stayed all deadlines for 30 days to July 14, 2023, removed the case from the court's active caseload, and required the parties to file a stipulation for dismissal or a new proposed schedule by that date. The reasons underlying the parties' joint request are not disclosed in the available record.

The defendants include Vevor Corporation, Vevor, Inc., Sanven Corporation, Fuyu Jiao, Rubao Jiao, James Liu, Shanghai Peixu Machinery Equipment Co. Ltd, Shanghai Sihao Machinery Equipment Co. Ltd, Shanghai Sishun E-Commerce Co. Ltd, Shanghai Sishun Machinery Equipment Co. Ltd, and Does. The defendant group spans U.S. distributors, Chinese manufacturers, e-commerce entities, and named individuals.

A case stay means the court has paused active proceedings without issuing a final judgment on the merits. In this case, the stay was entered jointly by the parties and the court simultaneously removed the case from its active docket. A stay does not resolve the underlying infringement claims; it suspends procedural deadlines pending a further order, dismissal, or agreed schedule.

Companies making, importing, or selling adjustable dumbbell systems in the U.S. should evaluate freedom-to-operate against US10518123B2, US7614982B2, and US8002680B2. Nautilus's decision to assert all three patents simultaneously against a multi-entity defendant group — including Chinese OEM-connected distributors — signals active enforcement. The specific claim scope of each patent should be independently analysed against target product designs.
