Parker-Hannifin vs. Faster, Inc.: Voluntary Dismissal in Fluid Coupling Patent Dispute
In a patent infringement dispute that concluded without a judicial ruling on the merits, Parker-Hannifin Corporation and Parker Intangibles, LLC voluntarily dismissed their claims with prejudice against Faster, Inc., Faster, SRL, and Helios Technologies, Inc. — ending Case No. 3:23-cv-01704 in the Northern District of Ohio just 190 days after filing.
Filed on August 30, 2023, and closed on March 7, 2024, the fluid coupling patent infringement case centered on two U.S. patents — US7568502B2 and US11435018B2 — covering parallel and perpendicular coupling technologies critical to hydraulic and fluid power systems. While the dismissal with prejudice forecloses any re-filing of identical claims, it leaves the competitive and licensing landscape largely unresolved publicly.
For patent attorneys, IP professionals, and R&D teams operating in the fluid power and hydraulic coupling space, this case offers meaningful lessons in litigation strategy, voluntary dismissal tactics, and freedom-to-operate (FTO) risk management.

Case Overview
The Parties
⚖️ Plaintiff
Global leader in motion and control technologies, with an extensive IP portfolio spanning hydraulics, pneumatics, and fluid management systems.
🛡️ Defendant
Specialized manufacturers of quick-release hydraulic coupling systems (Faster) and a major manufacturer of hydraulic components and control systems (Helios).
The Patents at Issue
This fluid coupling patent infringement action involved two patents covering parallel and perpendicular coupling technologies critical to hydraulic and fluid power systems. These patents are registered with the U.S. Patent and Trademark Office (USPTO) and protect functional innovations in quick-connect/disconnect hydraulic systems.
- • US7568502B2 — Covers innovations in fluid coupling technology, likely addressing valve or locking mechanisms.
- • US11435018B2 — A more recently issued patent, suggesting continued development and prosecution activity in Parker’s coupling IP portfolio.

Litigation Timeline & Procedural History
The case was filed in the U.S. District Court for the Northern District of Ohio, presided over by Chief Judge Jeffrey J. Helmick. The Northern District of Ohio is a strategically logical venue for Parker-Hannifin given the company’s Cleveland headquarters, establishing strong ties to the forum.
At approximately 190 days, the case resolved well within the typical district court litigation timeline of 2–3 years. The rapid resolution — before any claim construction hearing or summary judgment practice is publicly documented — strongly suggests that settlement negotiations or licensing discussions occurred in parallel with the litigation. No trial was conducted, and the case was terminated exclusively through a Notice of Voluntary Dismissal With Prejudice under Federal Rule of Civil Procedure 41(a).
The absence of documented defendant counsel in available records may reflect early-stage procedural posture at the time of dismissal.

The Verdict & Legal Analysis
Outcome
The case concluded via voluntary dismissal with prejudice, meaning Parker-Hannifin and Parker Intangibles elected to discontinue litigation permanently. A dismissal with prejudice — unlike a without-prejudice dismissal — bars the plaintiffs from re-filing the same claims against the same defendants based on the same patents and accused products. No damages award was issued. No injunctive relief was granted. Specific settlement terms, if any, were not publicly disclosed.
Key Legal Issues
The matter resolved before substantive judicial rulings, meaning there is no publicly available claim construction order, summary judgment opinion, or trial finding to analyze. The strategic implications of the voluntary dismissal, however, are analytically significant. Voluntary dismissals with prejudice at this procedural stage typically reflect a private settlement, a strategic reassessment of the IP, or a commercial resolution.
