Case Overview
The Parties
⚖️ Plaintiff
A Chinese fitness equipment manufacturer based in Changzhou, Jiangsu Province, actively enforcing U.S. patent rights against domestic competitors.
🛡️ Defendant
A U.S.-based entity holding intellectual property interests, named here as the accused infringer of the asserted fitness equipment patent.
The Patent at Issue
The patent at the center of this dispute is U.S. Patent No. 7,614,983 (Application No. 11/983,213), a granted U.S. utility patent covering technology related to adjustable fitness equipment. The ‘983 patent was asserted against the defendant’s commercialized products based on its claims governing the mechanical or functional configuration of adjustable resistance or structure systems commonly found in home fitness equipment.
- • US 7,614,983 — Adjustable fitness equipment technology
The Accused Products
Two products formed the basis of the infringement allegations:
- • The WHATAFIT Adjustable Product
- • The VEICK DIRECT Adjustable Product
Both products operate in the competitive adjustable fitness equipment segment — a market that experienced significant consumer growth during and after the pandemic period, intensifying patent enforcement activity across the sector.
Legal Representation
Plaintiff Counsel: Nicholas P. Zalany, Shaoyi Che, and Yizhou Liu, represented by Calfee, Halter & Griswold LLP (Cleveland) and YoungZeal – Frisco.
Defendant Counsel: Brian A. Coulter, Howard L. Wernow, James F. McCarthy III, and Matthew G. Vansuch, represented by Brouse McDowell – Canfield, Roetzel & Andress – Canfield, and Sand, Sebolt & Wernow Co., LPA.
The defendant’s deployment of three separate law firms signals that Bruno Intellectual Reserve mounted a substantive defense posture, likely involving parallel invalidity or non-infringement analysis prior to settlement discussions.

The Verdict & Legal Analysis
Outcome
The case was dismissed without prejudice by court order on May 15, 2025, following a settlement in principle between the parties. A final Stipulation of Dismissal with Prejudice was due by June 30, 2025. No damages amount was publicly disclosed. No injunctive relief was ordered by the Court, as resolution occurred at the parties’ initiative prior to any judicial merits determination.
Verdict Cause Analysis
The action was categorized as a straightforward infringement action under 35 U.S.C. § 271. No published claim construction rulings, summary judgment decisions, or PTAB inter partes review (IPR) petitions appear in the available record, indicating the parties did not litigate substantive patent validity or infringement questions to judicial resolution.
Legal Significance
Because this case resolved without a merits ruling, it carries no direct precedential value regarding the validity or enforceability of U.S. Patent No. 7,614,983 or its claim scope over adjustable fitness products. However, the case contributes to a discernible body of data showing that:
- Chinese manufacturing entities are increasingly plaintiff-side patent enforcers in U.S. federal courts.
- Fitness equipment patent disputes in this product category are settling pre-trial at a high rate.
- The Ohio Northern District is emerging as a viable forum for product-based patent infringement actions.
