⚖️ Plaintiff
Utah-based sleep technology company known for its proprietary hyper-elastic polymer grid technology and distinct IP portfolio in comfort layer innovations.
🛡️ Defendant
One of the largest mattress manufacturers globally, with brands like Tempur-Pedic and Sealy commanding substantial market share.
The Patent at Issue
At the center of this dispute was U.S. Patent No. US11317733B2 (Application No. US15/816983), directed to mattresses including an elastomeric cushioning element and a pocketed coil layer and related methods. This patent covers hybrid mattress constructions that combine advanced elastomeric materials—characteristic of Purple’s core technology—with pocketed spring systems, a design approach increasingly prevalent across the premium sleep product market.

The Verdict & Legal Analysis
Outcome
The case terminated through a joint stipulated dismissal with prejudice pursuant to Fed. R. Civ. P. 41(a)(1)(A)(ii). All of Purple’s infringement claims against Tempur Sealy were dismissed with prejudice, as were all of Tempur Sealy’s counterclaims against Purple. Each party agreed to bear its own attorneys’ fees and costs, with no damages awarded or injunctive relief granted.
Legal Significance
Because the dismissal is non-adjudicative, US11317733B2 remains valid and enforceable as a matter of patent law. Purple’s patent was neither invalidated nor found infringed by judicial determination, preserving Purple’s ability to assert the patent against third parties. This outcome reinforces that even complex patent disputes in consumer product categories frequently resolve before substantive rulings, often driven by negotiated settlements.
