Kohler Co. v. Sweethome: Default Judgment & Permanent Injunction on 13 Faucet Design Patents
Kohler Co. sued Sweethome d/b/a Sweethome247.com in the Central District of California, asserting 13 design patents covering bathroom and kitchen faucet aesthetics. Sweethome failed to appear, and the court granted Kohler a default judgment with a permanent injunction in 281 days — ending the dispute before any substantive defense was mounted.
Kohler wins default judgment on 13 faucet design patents in under a year
Kohler Co. filed suit on August 22, 2023 in the Central District of California against Sweethome, operating under the online retail brand Sweethome247.com. The complaint alleged infringement of 13 U.S. design patents — all covering ornamental aspects of bathroom sink faucets and kitchen faucets — through the sale of at least ten identified competing products, including basin faucets, widespread sink faucets, and swing-arm kitchen faucets bearing Sweethome model identifiers.
Sweethome did not file an answer or otherwise appear. The Clerk entered default on February 16, 2024, and Kohler subsequently moved for default judgment. On May 29, 2024, the court granted the application in full, entering a permanent injunction barring Sweethome, its officers, agents, affiliates, and all persons acting in concert with it from making, using, offering for sale, selling, or importing any product that embodies or is a colorable imitation of the inventions claimed in the 13 asserted patents.
The 281-day resolution is consistent with default-judgment timelines rather than a litigated outcome, and the absence of any defense leaves Kohler’s design patent claims judicially validated without adversarial scrutiny. The public record does not disclose any damages award or bond requirement in the available verdict text, which is notable given that default judgments in design patent cases frequently include statutory or actual damages. Whether monetary relief was also ordered in the full judgment document remains unclear from the excerpted record.
Filing to Default Judgment in 281 days
281 days — resolved faster than most contested patent cases, driven by defendant’s failure to appear
Default judgment entered: what the permanent injunction means for both parties
Default judgment: liability established without a merits contest
When a defendant fails to appear or respond, the court may enter a default and, on application, a default judgment. Here, the Clerk entered default on February 16, 2024, and the court granted Kohler’s application on May 29, 2024. The judgment is legally binding, but because no substantive defense was ever mounted, the validity and scope of the 13 design patents were never adversarially tested in this proceeding.
Fed. R. Civ. P. 55(b)Kohler secures a permanent injunction — enforcement now the key lever
The permanent injunction gives Kohler an enforceable court order against Sweethome and any entity acting in concert with it. This is a strong tool against repeat infringers and downstream sellers of the same products. However, default judgments cannot be used offensively to establish validity in future proceedings against different defendants; each new case requires independent proof. Kohler’s next challenge is practical enforcement, particularly against an online retailer that may have limited U.S. assets.
Permanent injunction grantedSweethome faces an injunction it never contested — appeal window remains open
Sweethome is now permanently enjoined from selling the identified faucet products and any colorable imitation. Despite the binding judgment, a defaulting defendant may move to set aside the default under Rule 55(c) or appeal if it can show good cause or excusable neglect. The practical likelihood of such a challenge is uncertain. Continued sales in violation of the injunction would expose Sweethome to contempt proceedings in federal court.
Injunction; contempt risk if violatedOnline faucet sellers: design patent enforcement risk is rising
This case is consistent with a broader trend of major plumbing brands using design patent portfolios — particularly USD design patents — to pursue online-only competitors selling aesthetically similar faucets. With 13 patents asserted across a single online retailer, Kohler signals a low tolerance for look-alike products. Companies sourcing or selling bathroom and kitchen faucets online should conduct design patent clearance before listing products that closely replicate the ornamental features of established brands.

Official order — verbatim text
The court’s default judgment language is comprehensive: it establishes federal subject matter jurisdiction, confirms Clerk’s entry of default, and enters a permanent injunction covering Sweethome and any entity in active concert with it. The ‘colorable imitations’ clause extends the injunction beyond the ten specifically identified products to any future design that a court could find substantially similar to the 13 asserted patents. Critically, because this is a default judgment rather than a contested ruling, it does not constitute a judicial finding of patent validity — a distinction that matters if Kohler seeks to rely on this case in future enforcement actions against other defendants.
USD585111S and 12 related patents — ornamental faucet design portfolio
All 13 patents asserted are U.S. design patents (USD series), covering the ornamental appearance — not the functional mechanics — of bathroom sink faucets and kitchen faucets. Design patents protect the visual characteristics of a product: its shape, configuration, and surface ornamentation. The application numbers span a range from US29/284136 to US29/684443, suggesting the portfolio was built over more than a decade of product design iteration. This breadth indicates a deliberate, layered strategy to protect Kohler’s faucet aesthetic across multiple product lines and form factors.
For competitors and online retailers, design patents in the faucet category present a distinct risk profile compared to utility patents. Infringement turns on the ‘ordinary observer’ test: whether an ordinary purchaser would find the accused product substantially similar to the patented design. Products that replicate the square, geometric, or minimalist aesthetic now dominant in premium bathroom hardware are particularly exposed. Kohler’s portfolio depth — 13 design patents across single-hole, widespread, and three-hole configurations — suggests it has systematically covered its major product lines against visual copycat risk.
Should you run an FTO against Kohler’s faucet design patent portfolio?
Any company designing, sourcing, importing, or selling bathroom sink faucets or kitchen faucets in the U.S. market — particularly through online channels — should assess exposure to Kohler’s design patent portfolio. The 13 patents in this case cover a range of faucet configurations and styles. Products with square body profiles, minimalist spouts, or double-handle deck-mount designs similar to Kohler’s commercial lines warrant specific clearance review before listing or importation.
PatSnap Eureka’s FTO Search Agent can map the visual claim scope of each USD patent in Kohler’s portfolio against your product designs, flag design-around opportunities, and surface any pending continuation applications that could extend the portfolio’s reach. Given that design patent infringement is assessed on overall visual impression rather than element-by-element comparison, a thorough FTO here requires visual similarity analysis — exactly the kind of multi-modal search Eureka is built for.

What this case signals for the faucet and plumbing hardware IP landscape
Kohler’s 13-patent default judgment illustrates how design patent portfolios are deployed offensively against online retail competitors.
Design patent portfolios are potent enforcement tools against e-commerce sellers
Kohler asserted 13 design patents in a single action against one online retailer. This stacking strategy maximises injunctive scope while minimising the chance that any single patent invalidity argument defeats the entire case. Competitors selling faucets online should assume that major brands hold similarly deep design patent portfolios and will enforce them.
Default judgments resolve cases fast — but leave validity untested
This case closed in 281 days through default, not litigation. While Kohler’s injunction is enforceable, the design patents themselves were never subject to adversarial invalidity challenge. A future defendant with resources to litigate could still contest validity — meaning the portfolio’s actual litigation strength is not confirmed by this outcome.
Kohler v Sweethome — key questions answered
The Central District of California entered a default judgment in favour of Kohler Co. on May 29, 2024, after Sweethome failed to appear. The court issued a permanent injunction barring Sweethome and entities in concert with it from making, using, selling, or importing products infringing Kohler’s 13 asserted design patents.
Kohler asserted 13 U.S. design patents, including USD585111S, USD852326S, USD767722S, USD844110S, USD844752S, USD767732S, USD583022S, USD778408S, USD767734S, USD823441S, USD855775S, USD855780S, and USD855779S — all covering ornamental designs for bathroom sink and kitchen faucets.
A default judgment does not constitute a judicial finding of patent validity. Because Sweethome never appeared to contest the claims, the design patents were not subject to adversarial invalidity challenge in this proceeding. Future defendants could still challenge validity in separate litigation.
Ten products were identified, including basin faucets, widespread sink faucets, a Nordic-style geometric faucet, a single-hole vessel sink faucet, a three-section swing arm kitchen faucet, and several double-handle deck-mount bathroom faucets — all sold by Sweethome under various model identifiers on its e-commerce platform.
Yes. The injunction expressly covers Sweethome’s officers, agents, affiliates, servants, employees, attorneys, and all persons in active concert or participation with Sweethome. This standard language is designed to prevent circumvention through corporate restructuring or use of alter-ego entities, and violation would expose those parties to federal contempt proceedings.
