Case Overview
The Parties
⚖️ Plaintiff
Chinese houseware manufacturer with commercial interests in the U.S. consumer market, particularly in expandable and flexible garden hose products.
🛡️ Defendant
Well-known U.S.-based direct-to-consumer products company, recognized for its “As Seen on TV” product lines and frequent participation in consumer product patent litigation.
The Patents at Issue
This case involved two U.S. patents covering expandable water hose technology—a commercially competitive product category that has seen numerous manufacturers clash over intellectual property boundaries. Both patents relate to the design, structure, or functional mechanisms of expandable water hoses.
- • US 11,608,915 B2 — Later-generation expandable water hose technology
- • US 10,174,870 B2 — Earlier expandable water hose technology family

The Verdict & Legal Analysis
Outcome
The case was dismissed in its entirety by Chief Judge Hall. No damages were awarded, and no injunctive relief was granted. The dismissal was based on the failure of federal claims, leading the court to decline supplemental jurisdiction over state-law claims under 28 U.S.C. § 1367(c).
Jurisdictional Analysis: The Core Issue
The determinative legal issue was subject-matter jurisdiction, not patent validity or infringement. The court’s order explicitly stated: “As the Court is dismissing the federal claims, and as Plaintiff has not offered another basis for jurisdiction over the state-law claims, the Court will dismiss those claims.” This outcome highlights the discretionary nature of supplemental jurisdiction when federal anchors fail.
The critical question for practitioners is the specific basis for the dismissal of the federal patent claims, which was not detailed in the public summary but is key to understanding the full procedural context.

The case involved U.S. Patent No. 11,608,915 B2 and U.S. Patent No. 10,174,870 B2, both covering expandable water hose technology.
The court dismissed the federal patent claims and subsequently declined supplemental jurisdiction over the plaintiff’s state-law claims under 28 U.S.C. § 1367(c), as the plaintiff offered no alternative jurisdictional basis.
The patents remain enforceable. Companies in this space should maintain current FTO clearance and monitor for refiling or continuation-based assertions by the plaintiff.
