The lululemon Costco lawsuit is a design patent dispute where lululemon accuses Costco of selling knockoff athletic clothing that copies its protected designs. As of 2026, this case remains one of the most watched intellectual property fights in the retail industry.
No public consumer settlement fund has been announced yet. But the case carries serious implications for shoppers who bought the disputed products at Costco.
In this article, you’ll get the full breakdown of what happened, which products are involved, the current case status, potential payouts, and whether everyday consumers stand to gain anything. One striking detail: lululemon’s design patents cover specific visual elements down to the waistband stitching pattern.
This isn’t just a billion-dollar brand protecting its turf. It’s a case that could reshape how warehouse retailers approach private-label athletic wear.
Lululemon Costco Lawsuit
The lululemon Costco lawsuit is a federal intellectual property case in which lululemon athletica inc. accuses Costco Wholesale Corporation of selling athletic apparel that infringes on its design patents and trade dress rights. The core claim is that Costco sold leggings and other athletic wear that looked nearly identical to lululemon’s signature products.
Lululemon filed the original complaint in U.S. District Court, alleging that Costco’s products copied specific design elements. These elements include waistband construction, seam placement, and overall garment silhouette.
The case isn’t a typical consumer class action. It’s a brand-versus-retailer dispute. But it has consumer ripple effects that matter.
| Quick Facts | Details |
|---|---|
| Plaintiff | lululemon athletica inc. |
| Defendant | Costco Wholesale Corporation |
| Case Type | Design patent and trade dress infringement |
| Court | U.S. District Court |
| Products at Issue | Athletic leggings and apparel |
| Original Filing | 2022 |
Think of it like this: if someone photocopied your handwriting and sold it as their own calligraphy, you’d be upset. That’s essentially what lululemon claims happened with its clothing designs.
The lawsuit specifically references lululemon’s Align pant line. That product alone generates hundreds of millions in annual revenue. Costco allegedly sold similar-looking items at a fraction of the price.
Lululemon Costco Lawsuit Update 2026
As of 2026, the lululemon Costco lawsuit is still progressing through the court system with no final resolution announced. Discovery has been ongoing, and both sides have filed multiple motions.
The case has not gone to trial yet. Settlement discussions may be happening behind closed doors, but nothing has been publicly confirmed.
Key developments to watch for in 2026 include:
- Summary judgment motions from either side
- Expert witness reports on design patent validity
- Potential trial date setting by the court
- Any preliminary injunction orders that could force Costco to stop selling disputed products
| 2026 Status | Details |
|---|---|
| Trial Date | Not yet scheduled publicly |
| Settlement Status | No public settlement announced |
| Discovery Phase | Ongoing |
| Injunction | No public order issued |
Both companies have strong legal teams. Lululemon has a track record of aggressively protecting its intellectual property. Costco, on the other hand, has deep pockets and a history of fighting litigation rather than settling early.
Court watchers expect movement on this case in late 2026. IP disputes of this size typically take three to five years from filing to resolution.
Lululemon Costco Settlement
No lululemon Costco settlement has been publicly announced as of 2026. The case remains in active litigation, and neither party has confirmed any settlement talks.
That doesn’t mean a settlement won’t happen. Most intellectual property lawsuits in the retail space eventually settle before trial. The numbers just haven’t been made public yet.
If a settlement does occur, it would likely involve:
- A financial payment from Costco to lululemon
- A permanent injunction preventing Costco from selling the disputed products
- Possible licensing terms for future product designs
- Potential consumer relief if a class action component is added
| Settlement Scenario | Likelihood |
|---|---|
| Private financial settlement | High |
| Public consumer payout fund | Low to moderate |
| Injunction against Costco | Moderate to high |
| Licensing agreement | Low |
In similar cases, like Nike’s design patent disputes, settlements have ranged from tens of millions to over $100 million. The exact figure depends on proven damages, sales volume of infringing products, and whether the infringement was willful.
Keep an eye on court docket filings. A sudden pause in litigation activity often signals that settlement negotiations are underway.
Key Takeaway: The lululemon Costco lawsuit is active in 2026 with no public settlement yet, but the case could resolve through private negotiations at any time.
Lululemon Costco Lawsuit Payout
The lululemon Costco lawsuit payout has not been determined because the case has not reached a verdict or public settlement. However, potential damages could be significant based on the legal claims involved.
Under 35 U.S.C. Section 289, design patent infringement damages can include the total profit earned from the infringing product. That’s not a typo. The law allows the patent holder to claim the entire profit, not just a percentage.
Here’s what the potential payout structure could look like:
| Payout Category | Estimated Range |
|---|---|
| Design patent damages (total profit) | $10 million to $100 million+ |
| Trade dress damages | $5 million to $50 million |
| Enhanced damages (willful infringement) | Up to 3x base damages |
| Attorney fees | $2 million to $10 million |
These numbers are estimates based on comparable IP cases in the fashion and retail sectors. Actual amounts depend on Costco’s sales data for the accused products.
For consumers, the picture is different. If no consumer class is certified, individual shoppers won’t receive direct payouts. The money would flow from Costco to lululemon.
But if a consumer component emerges, buyers of the knockoff products might receive small refunds or store credits. That’s a big “if” at this stage.
Who Qualifies for the Lululemon Costco Lawsuit
Right now, no individual consumers qualify for any payout from the lululemon Costco lawsuit. This is a business-to-business intellectual property dispute, not a consumer class action.
Lululemon is the plaintiff. Costco is the defendant. Consumers aren’t named as a class.
That said, there are scenarios where consumers could become involved:
- If Costco’s products are found to be deceptive, a separate consumer protection claim could be filed
- If consumers were misled into thinking they were buying genuine lululemon products, a fraud-based class action could emerge
- If a settlement includes a consumer fund, Costco shoppers who bought the specific products might be eligible
| Eligibility Scenario | Who Would Qualify |
|---|---|
| Current lawsuit (IP dispute) | Only lululemon as plaintiff |
| Potential consumer class action | Costco shoppers who bought accused products |
| Consumer protection claim | Buyers who were allegedly misled |
If you bought athletic leggings from Costco that looked like lululemon products, save your receipt. You might need it later if a consumer claim opens up.
The best move right now is to stay informed. No claim forms exist yet for individual shoppers.
Why Lululemon Sues Costco
Lululemon sues Costco because the athletic brand believes Costco sold products that directly copy its patented clothing designs. This isn’t about a vague similarity. Lululemon points to specific, registered design patents.
The company has invested millions in developing the look and feel of its products. When a retailer sells near-identical items at a steep discount, it threatens the brand’s market position.
Here are the specific legal grounds lululemon cited:
- Design patent infringement under U.S. patent law
- Trade dress infringement under the Lanham Act
- Unfair competition claims
- Unjust enrichment
Lululemon argues that its design elements aren’t just aesthetic. They’re functional identifiers that consumers associate with the brand. When Costco sells lookalikes, it creates confusion.
| Legal Claim | Law | What It Means |
|---|---|---|
| Design patent infringement | 35 U.S.C. Section 289 | Costco copied protected visual designs |
| Trade dress infringement | Lanham Act | Products mimic lululemon’s distinctive look |
| Unfair competition | State and federal law | Costco gained unfair market advantage |
| Unjust enrichment | Common law | Costco profited from lululemon’s designs |
It’s like a restaurant copying another restaurant’s signature dish down to the plating. The recipe might be different, but the presentation is what customers recognize. That presentation is what lululemon is protecting.
Key Takeaway: Lululemon filed suit on multiple legal grounds, arguing that Costco’s products copy not just the style but the specific protected design elements that consumers identify with the brand.
Lululemon vs Costco Lawsuit Explained
The lululemon vs Costco lawsuit is a fight between a premium athletic brand and a wholesale retail giant over who has the right to sell products with certain design features. At its core, this is about intellectual property boundaries in fashion.
Lululemon says its designs are legally protected. Costco says its products are different enough. The court will decide.
Here’s the simplified breakdown:
Lululemon’s argument:
- We own registered design patents
- Costco’s products look substantially similar
- Consumers could confuse Costco’s products with ours
- We’ve lost sales because of the cheaper knockoffs
Costco’s likely defense:
- The designs are not similar enough to infringe
- Lululemon’s design patents may be invalid
- Consumers know the difference between a $100 product and a $20 product
- General design elements can’t be monopolized
| Side | Core Argument |
|---|---|
| Lululemon | Our designs are protected and Costco copied them |
| Costco | Our products are different and the patents may be too broad |
Design patent cases in fashion are notoriously tricky. The “ordinary observer” test asks whether an average buyer would think the two products are the same. That’s the standard the court will apply.
A jury, if the case goes to trial, will look at the products side by side. Visual comparison matters more than technical specifications in design patent cases.
Lululemon Costco Clothing Design Lawsuit
The lululemon Costco clothing design lawsuit centers on specific garment features that lululemon claims are uniquely its own. These are not broad claims about “athletic leggings” in general. They target precise design elements.
The products in question include leggings, pants, and other athletic apparel sold at Costco. Lululemon’s complaint identifies particular design patents that cover visual characteristics of these garments.
Specific design elements at issue include:
- Waistband shape and width
- Seam placement along the legs
- Back pocket design and positioning
- Overall silhouette proportions
- Fabric panel arrangement
| Design Element | Lululemon Product | Accused Costco Product |
|---|---|---|
| High-rise waistband | Align pant signature feature | Allegedly similar construction |
| Seam lines | Distinctive curved seaming | Reportedly matching pattern |
| Back detail | Specific pocket/logo placement | Accused of copying layout |
Lululemon holds multiple design patents filed with the U.S. Patent and Trademark Office. Each patent covers a specific visual aspect of the garment. These patents give lululemon the exclusive right to use those design features for a set period.
What makes this case interesting is the specificity. Lululemon isn’t saying “you can’t make leggings.” It’s saying “you can’t make leggings that look exactly like ours in these particular ways.”
Costco Lululemon Knockoff Lawsuit
The Costco lululemon knockoff lawsuit boils down to one question: did Costco sell products that are close enough to lululemon’s designs to qualify as knockoffs under patent law? Lululemon says yes. Costco’s position is that its products are independently designed.
The word “knockoff” is important here. In legal terms, a knockoff isn’t the same as a counterfeit. A counterfeit carries the original brand’s logo or trademark. A knockoff copies the design without using the brand name.
Here’s the distinction:
| Term | Definition | Applies Here? |
|---|---|---|
| Counterfeit | Fake product with the original brand name/logo | No |
| Knockoff | Product that copies design elements without the brand | Yes, per lululemon’s claim |
| Inspired-by | Product with general similarities but distinct differences | Costco’s likely argument |
Costco didn’t put a lululemon logo on its products. But lululemon argues the design itself is so distinctive that copying it is enough to infringe.
The knockoff question gets complicated in fashion because trends spread quickly. Everyone makes high-waisted leggings. The court has to determine whether Costco crossed the line from “following a trend” to “copying a specific protected design.”
This distinction is where the case will likely be won or lost.
Key Takeaway: The knockoff versus inspired-by distinction is the central battleground, and the court’s ruling on this question will determine whether Costco infringed or simply competed in the same product category.
Lululemon Design Patent Lawsuit
The lululemon design patent lawsuit against Costco relies on U.S. design patent law, which protects the ornamental appearance of a functional item. Unlike utility patents, which protect how something works, design patents protect how something looks.
Lululemon holds several registered design patents covering its most popular products. These patents were granted by the U.S. Patent and Trademark Office after examination.
Key facts about design patents in this case:
- Duration: Design patents last 15 years from the grant date
- Scope: They cover the specific visual appearance shown in patent drawings
- Test for infringement: The “ordinary observer” test
- Damages: Total profits from the infringing article under Section 289
| Design Patent Basics | Details |
|---|---|
| Protection type | Ornamental appearance of a product |
| Duration | 15 years from grant |
| Infringement standard | Ordinary observer test |
| Maximum damages | Total profit from infringing article |
| Relevant statute | 35 U.S.C. Section 289 |
The ordinary observer test asks a simple question. Would a regular buyer, familiar with the existing designs in the market, think the accused product is the same as the patented design? If yes, infringement exists.
Design patent lawsuits in fashion have increased dramatically over the past decade. Brands like Nike, Adidas, and now lululemon have used them as primary tools for protecting their product aesthetics.
The strength of lululemon’s case depends on how distinctive its patented designs are compared to what already existed in the market before the patents were filed.
Lululemon Trade Dress Infringement Against Costco
Lululemon’s trade dress claim argues that the overall visual impression of its products is so distinctive that copying it creates consumer confusion. Trade dress is separate from design patents. It covers the total image and appearance of a product.
Under the Lanham Act, trade dress is protectable if it is distinctive and non-functional. Lululemon needs to prove two things: that its trade dress is recognizable to consumers and that Costco’s products are likely to cause confusion.
Elements of lululemon’s trade dress argument:
- The combination of design features creates a unique overall look
- Consumers associate that look with the lululemon brand
- Costco’s products replicate that overall look closely enough to confuse buyers
- The copied elements are not functional but purely ornamental
| Trade Dress vs. Design Patent | Key Difference |
|---|---|
| Trade dress | Protects the overall commercial impression |
| Design patent | Protects a specific ornamental design |
| Trade dress requirement | Must show consumer recognition |
| Design patent requirement | Must be registered with USPTO |
Trade dress claims are harder to prove than design patent claims. Lululemon must demonstrate through consumer surveys, marketing evidence, and sales data that people see a product and immediately think “that’s lululemon.”
If the brand can prove that Costco’s products trigger that association, the trade dress claim becomes powerful. If not, this part of the case may fall away while the design patent claims continue.
Was Costco Selling Lululemon Knockoffs
Yes, according to lululemon’s complaint, Costco was selling athletic apparel that lululemon considers knockoffs of its protected designs. Costco has not publicly admitted to this characterization. The products were sold under Costco’s own branding, not the lululemon name.
The products appeared in Costco stores and potentially on Costco’s website. They were priced significantly lower than genuine lululemon products, which typically retail for $88 to $128 for leggings.
Here’s a price comparison:
| Product | Lululemon Price | Costco Price (Accused Products) |
|---|---|---|
| Athletic leggings | $88 to $128 | Estimated $15 to $30 |
| Yoga pants | $98 to $138 | Estimated $18 to $35 |
That price gap is part of what makes this case contentious. Lululemon argues the low price point drives consumers to buy the knockoff instead of the original, directly eating into its sales.
Costco operates on a model of offering quality products at warehouse prices. Its buyers source products from various manufacturers. Whether those manufacturers independently created similar designs or intentionally copied lululemon is a factual question the court must resolve.
Physical product comparisons, expert testimony, and internal communications at Costco will likely play a major role in determining the answer.
Key Takeaway: Costco sold lower-priced athletic wear that lululemon claims copies its protected designs, and the court will need product-by-product comparisons to determine whether infringement occurred.
Lululemon Costco Lawsuit Consumer Impact
The consumer impact of the lululemon Costco lawsuit is currently limited because this is not a consumer class action. However, the outcome could affect shoppers in several indirect ways.
If lululemon wins, Costco may be forced to pull certain products from its shelves. That means fewer affordable athletic wear options for Costco members.
Potential impacts on consumers:
- Reduced product availability at Costco for certain athletic apparel
- Higher prices if Costco can no longer offer similar designs at low cost
- Possible consumer claims if a court finds consumers were misled
- Industry-wide changes in how retailers source athletic wear designs
| Consumer Impact Area | Potential Effect |
|---|---|
| Product selection | Fewer lookalike products at Costco |
| Pricing | Possible price increases for athletic wear |
| Consumer claims | Only if a separate class action is filed |
| Shopping behavior | More awareness of design authenticity |
For the average Costco shopper, the most immediate question is whether those $20 leggings will still be available. If lululemon obtains an injunction, the answer could be no.
Long-term, this case could set a precedent that makes all warehouse retailers more cautious about the athletic wear they stock. That’s good news for brands protecting their designs. It’s mixed news for bargain hunters.
Lululemon Costco Case Timeline
The lululemon Costco case timeline stretches from the original filing in 2022 through ongoing litigation in 2026. Here is a chronological overview of the key milestones and projected events.
| Date | Event |
|---|---|
| 2022 | Lululemon files original complaint against Costco |
| 2022 to 2023 | Initial pleadings, Costco responds |
| 2023 to 2024 | Discovery phase begins, document production |
| 2024 to 2025 | Expert reports filed, depositions conducted |
| 2025 to 2026 | Summary judgment motions expected |
| Late 2026 to 2027 | Possible trial date or settlement |
IP cases of this magnitude typically take three to five years from filing to resolution. That puts the resolution window somewhere between 2025 and 2027.
Several factors could speed up or slow down the timeline:
- Settlement talks could resolve the case any time
- Appeals on key motions could add months or years
- Court scheduling in the relevant district affects trial dates
- Complexity of damages calculations can extend proceedings
The discovery phase is often the longest part. Both sides exchange thousands of documents, including internal emails, product development records, sales data, and sourcing agreements.
If the case survives summary judgment, a trial could happen in late 2026 or early 2027. Jury trials in design patent cases typically last one to two weeks.
Similar Design Patent Lawsuit Settlements
Looking at similar design patent lawsuit settlements helps estimate what might happen in the lululemon Costco case. Several high-profile fashion and athletic wear IP disputes have resolved in recent years with significant payouts.
| Case | Year | Outcome |
|---|---|---|
| Nike vs. Skechers (design patents) | 2016 to 2021 | Settled confidentially, estimated $30M+ |
| Adidas vs. Forever 21 (three-stripe trade dress) | 2017 to 2019 | Settled, terms confidential |
| Samsung vs. Apple (design patents) | 2012 to 2018 | $539 million jury verdict |
| Lululemon vs. Under Armour (sports bra) | Previous | Settled confidentially |
| Crocs vs. multiple defendants | Various | Multiple settlements, $5M to $50M range |
The Samsung v. Apple case is the landmark design patent decision. The Supreme Court ruled on the meaning of “article of manufacture” in Section 289, which directly affects how damages are calculated in cases like lululemon v. Costco.
Before that ruling, patent holders could claim the total profits from the entire product. After the ruling, courts must determine whether damages should be based on the whole product or just the infringing design component.
This distinction matters enormously for lululemon. If damages are calculated on the entire garment’s profit, the payout is much larger. If limited to the specific design element, it shrinks.
Most fashion IP cases settle before trial. The cost of litigation, the risk of a bad precedent, and the desire for confidentiality all push both sides toward a private resolution.
Key Takeaway: Comparable design patent cases have settled for amounts ranging from $5 million to over $500 million, making the financial stakes in the lululemon Costco dispute potentially very high.
