Zhong YIN

There is no public record of a distinct company operating under the name Zhong YIN in relation to the tracked litigation. Court records show Zhong YIN is a named defendant in a patent lawsuit alongside Ningbo Huayue Dianzi Shangwu Youxian Gongsi, which does business as "LIONSCOOL". Given the nature of the lawsuit, it is likely that Zhong YIN is an individual, an online storefront name, or a small, private business. No information regarding its location, employee count, or revenue is publicly available.

The lawsuit was filed by Ritfit LLC, a seller of fitness equipment. Court filings in the case reference the "Defendants' stores," which suggests that Zhong YIN is an online retailer of products alleged to infringe upon the plaintiff's patents. The specific products at issue are likely related to the fitness equipment sold by Ritfit.

Zhong YIN's patent litigation posture is that of a defendant. The company's only tracked case is one in which it is defending against a patent infringement claim. This pattern is consistent with that of an operating company or seller being sued by a competitor or patent holder. The case was filed in the U.S. District Court for the Northern District of Illinois, a common venue for patent and trademark cases targeting multiple online sellers.

The only notable case involving Zhong YIN is Ritfit LLC et al. v. Ningbo Huayue Dianzi Shangwu Youxian Gongsi et al., filed on April 17, 2026. The case appears to be a typical patent enforcement action by a brand owner against multiple online sellers.
