Case Overview
The Parties
⚖️ Plaintiff
A plaintiff asserting patent rights in the industrial containment bag market—a sector serving oil and gas, HVAC, and petrochemical industries.
🛡️ Defendant
An accused infringer and competing company offering industrial containment products that allegedly overlapped with the plaintiff’s patented technology.
Patents at Issue
This case centered on three U.S. patents covering industrial containment bag technology, specifically for equipment such as fin fan coolers during maintenance operations.
- • US9387524B2 — Covering containment bag design and deployment technology
- • US7753090B2 — An earlier-generation patent in the same technology family
- • US9586725B2 — An additional patent covering related containment system configurations

The Verdict & Legal Analysis
Outcome
On April 22, 2024, Judge Alfred H. Bennett signed Order No. 57, granting the parties’ Joint Motion to Dismiss all of the plaintiff’s claims and all of the defendant’s counterclaims with prejudice. No damages award was publicly disclosed, and no injunctive relief was entered. The case was formally terminated.
Legal Significance
The “with prejudice” designation on both sides is legally significant: it bars any future re-filing of the same claims or counterclaims by either party, and it strongly implies a negotiated resolution (whether a settlement, licensing deal, or covenant not to sue) was reached privately. This outcome is common in competitive industrial product markets where parties prefer confidential resolution over public adjudication.
The presence of counterclaims from HEXA Containment — also dismissed with prejudice — indicates the defendant likely asserted invalidity challenges or non-infringement defenses, contributing to a balanced negotiating outcome.

Three U.S. patents were asserted: US9387524B2, US7753090B2, and US9586725B2, all covering industrial containment bag technology used in maintenance applications such as fin fan cooler servicing.
The case was resolved via a Joint Motion to Dismiss (Docket No. 57), signed by Judge Alfred H. Bennett on April 22, 2024. Both plaintiff’s claims and defendant’s counterclaims were dismissed with prejudice, indicating a privately negotiated resolution.
It reinforces the enforceability of niche industrial product patents and signals that competitors in the containment bag market face active IP assertion risk, making proactive FTO analysis essential.
