80 F.4th 536
5th Cir.2023Background
- Whirlpool owns federally registered three-dimensional trade dress and design marks for the KitchenAid stand mixer (registered 1992) and extensively markets the design.
- Shenzhen (brands COOKLEE and PHISINIC) introduced stand mixers with similar exterior styling and sold them primarily online.
- Whirlpool sued Shenzhen (Jan 31, 2022) for trademark/trade dress infringement and moved for a preliminary injunction the same day.
- Shenzhen received notice and appeared at the preliminary-injunction hearing but argued lack of service, functionality of the mark, and no likelihood of confusion.
- The magistrate judge recommended, and the district court adopted, a preliminary injunction requiring Shenzhen to stop sales and to recall and hold (modified from destroy) allegedly infringing mixers and required Whirlpool to post a $10,000 bond; Shenzhen appealed and sought stays, which were denied.
- The Fifth Circuit affirmed the preliminary injunction on appeal, rejecting Shenzhen’s jurisdiction and merits challenges.
Issues
| Issue | Whirlpool's Argument | Shenzhen's Argument | Held |
|---|---|---|---|
| Whether Rule 65 requires formal service (personal jurisdiction) before issuing a preliminary injunction | Notice sufficed; Rule 65 permits injunctions on notice to adverse party | Court lacked power without completed Hague service or voluntary appearance | Affirmed: Rule 65 requires notice, not perfected service; appearance/participation was sufficient (Corrigan controls) |
| Validity of KitchenAid design mark (functionality) | Design is ornamental/nonfunctional and entitled to protection | Exterior design is functional or tied to mixer operation | Affirmed: District court did not clearly err; design is nonfunctional under TrafFix/Qualitex tests |
| Likelihood of confusion between products | Similar overall look, same channels and purchasers create likelihood of confusion | Distinguishable features, branding, and differences negate confusion | Affirmed: Court’s factual finding of likelihood of confusion not clearly erroneous (weighing digits of confusion) |
| Other preliminary-injunction factors (irreparable harm, balance of harms, public interest) | Presumption of irreparable harm upon likelihood of success; public interest in preventing consumer confusion | Shenzhen: economic harms, market loss; alleged marketplace coexistence and delay rebut irreparable harm | Affirmed: Presumption of irreparable harm stood; monetary harms weigh as reparable; public interest supports injunction |
