Defendant
1 case as defendant.
Ningbo Huayue Dianzi Shangwu Youxian Gongsi is a Chinese company that operates under the brand name LIONSCOOL. The company's legal address is in the Yinzhou District of Ningbo, Zhejiang, China. Operating as LIONSCOOL, the company was founded in 2020 and has established itself as a fast-growing, private entity focused on the home fitness market. Specific details on its employee count and revenue are not publicly available.
LIONSCOOL designs and sells performance-oriented home gym and strength-training equipment. Its product lines include plate-loaded machines such as leg extension/curl machines, 3-in-1 leg press/hack squat machines, and back extension benches. The company also offers a range of free weights and accessories, including Olympic barbells, weight plates, dumbbells, and storage racks. The brand emphasizes affordability and durable construction for users building home gyms.
As a defendant in its only tracked U.S. patent litigation case, Ningbo Huayue Dianzi Shangwu Youxian Gongsi appears to be an operating company defending its products. The case count of zero suits as a plaintiff and one as a defendant is typical for a manufacturer or retailer facing infringement claims. The single case was filed in the Northern District of Illinois, not a jurisdiction commonly associated with high-volume patent assertion campaigns.
The company's notable litigation is the 2026 patent suit Ritfit LLC et al. v. Ningbo Huayue Dianzi Shangwu Youxian Gongsi et al. In that case, the company is listed alongside other defendants and is identified by its legal name and its "doing business as" name, LIONSCOOL. The plaintiff, Ritfit, is also a seller of home fitness equipment, suggesting the dispute is between direct competitors in the fitness market.
The accused product is a leg extension and curl machine sold by RITFIT.
