Lululemon Costco Lawsuit 2026: Case Status, Settlements, and What Shoppers Should Know
Quick Answer
- The lawsuit is real: Lululemon sued Costco June 27, 2025, case number 2:25-cv-05864, Central District of California.
- There is no payout for Costco shoppers. This is a business trade dress dispute, not a consumer class action.
- The next key date is July 31, 2026, the deadline for court-ordered mediation on the last unresolved claim.
If you’re searching “Lululemon Costco lawsuit” wondering whether you’re owed money for buying a Kirkland jacket, here’s the direct answer: you’re not. This case is Lululemon suing Costco over alleged design copying, not a consumer class action with a claims process.
The lawsuit accuses Costco of selling “confusingly similar” versions of Lululemon’s Scuba hoodie, Define jacket, and ABC pants under private labels like Kirkland Signature, Danskin, Jockey, and Spyder. Since filing in June 2025, the two companies have quietly settled most of the disputed products one by one.
This article breaks down what’s actually confirmed in the court record: which products remain in dispute, what’s already settled, and the one date worth watching before the end of July 2026. One detail most coverage skips: Lululemon isn’t suing the manufacturers who made the disputed products, only Costco itself.

Is the Lululemon Costco lawsuit real?
Yes, the Lululemon Costco lawsuit is a real, active federal case, filed June 27, 2025 in the U.S. District Court for the Central District of California. The case is officially captioned lululemon athletica canada inc. et al. v. Costco Wholesale Corporation, case number 2:25-cv-05864, before Judge Fernando L. Aenlle-Rocha.
Lululemon accuses Costco of selling knockoff versions of its bestselling apparel, close enough in design to confuse shoppers, a legal claim known as trade dress infringement. The complaint also raises design patent infringement, trademark infringement, and unfair competition claims under California law.
This is confirmed through public federal court docket records, not just news reports. Costco has not publicly denied that the lawsuit exists, though it has disputed the underlying claims through formal counterclaims filed in October 2025.
Key Takeaway: The lawsuit is confirmed and active in federal court, but it’s a fight between two companies, not a case Costco shoppers are part of.
Can Costco shoppers get money from the Lululemon Costco lawsuit?
No. Costco shoppers cannot get money from this lawsuit because it is not a consumer class action. It is an intellectual property dispute between Lululemon and Costco over alleged design copying.
Lululemon’s complaint seeks a court order stopping Costco from selling the disputed products, plus unspecified monetary damages paid from Costco to Lululemon, not to individual customers. No part of the case creates a refund or reimbursement path for people who bought the items in question.
Think of it like a dispute between two competing bakeries over a cake recipe. Even if one bakery wins damages from the other, the customers who bought the cake don’t get a check; the money moves between the businesses.
Is there a settlement fund for consumers in the Lululemon Costco case?
Not applicable. No settlement fund for consumers exists in this case, and none is expected, because the lawsuit was never structured as a class action in the first place.
The settlements reached so far in this case, covering the Kirkland pants, Danskin and Jockey outerwear, and the Spyder yoga jacket, are all confidential business-to-business agreements between Lululemon, Costco, and the relevant suppliers. None of them created a fund, a claims administrator, or a claim form for shoppers.
Reality Check: If you see a website, text, or social post claiming you can file a claim for money from the “Lululemon Costco lawsuit,” that’s not connected to this case. No legitimate settlement notice for this lawsuit would ever ask a Costco shopper to submit a claim, because no such claims process exists here.
Can I file a claim in the Lululemon Costco lawsuit?
No, there is no claim to file, since this case has no consumer compensation component at any stage. Unlike a product recall settlement or a data breach class action, this lawsuit doesn’t include a mechanism for shoppers to recover money.
If you’re looking for a legitimate class action to file a claim in, this isn’t it. Steps to confirm whether you actually qualify for a different, real consumer settlement:
- Search the specific product or company name plus “class action settlement”
- Check for an official court-approved settlement administrator website
- Look for a confirmed case number and court name
- Verify a stated claim deadline directly on that official site
- Avoid any site asking for payment to “process” your claim
None of those steps apply to the Lululemon Costco case, because it simply isn’t a claims-eligible settlement for consumers.
How do I follow the Lululemon Costco lawsuit case status?
You can follow the Lululemon Costco lawsuit through the federal court’s public docket for case number 2:25-cv-05864 in the Central District of California. This is the same record attorneys and reporters use to track the case.
- U.S. District Court, Central District of California, public docket for case 2:25-cv-05864

Avoid unofficial “lawsuit tracker” sites that ask for your email before showing basic public docket information that’s already free through the court system.
Key Takeaway: There is no consumer fund, claim form, or administrator tied to this case, at any point in its timeline so far.
What is the latest update in the Lululemon Costco lawsuit?
As of May 2026, Lululemon and Costco settled all disputed products except claims tied to one men’s zip-up jacket. The most recent confirmed settlement, filed as a joint stipulation, resolved trademark infringement claims over a women’s yoga jacket sold under the Spyder brand.
That followed two earlier settlements: one in February 2026 resolving claims tied to outerwear sold under Moret’s Danskin and Jockey brands, and another in April 2026 covering Kirkland-branded pants. Manufacturer Jacques Moret Inc. was also dismissed from the case as part of the February settlement.
Only one disputed product remains contested as of the most recent public filings: the Hi-Tec Men’s Scuba Full Zip jacket, priced around $19.97 at Costco compared to Lululemon’s original jackets, which retail above $100.
When is the next date in the Lululemon Costco lawsuit?
What Happens Next
- July 31, 2026 (confirmed): Deadline for court-ordered mediation on the remaining disputed jacket claim, ordered by the court on October 16, 2025.
- Expected following mediation: A joint status statement from both parties on whether the final claim settled or heads toward further litigation.
- Not yet confirmed: Any trial date, since none has been set as of mid-2026.
- Possible outcome: A final settlement covering the last jacket, similar to the pattern set by the four prior settlements in this case.
- Alternative outcome: If mediation fails, the case could proceed to discovery and potentially trial, extending into 2027.
What products are named in the Lululemon Costco lawsuit?
The lawsuit names several Costco products across multiple private-label and third-party brands, each compared directly to a specific Lululemon original. The complaint pairs each item side by side with its Lululemon counterpart.
| Costco Product | Lululemon Original | Status |
|---|---|---|
| Kirkland Signature Men’s 5-Pocket Performance Pants | ABC Pants | Settled (April 2026) |
| Danskin Ladies Half-Zip Hoodie / Pullover | Scuba Hoodie | Settled (February 2026) |
| Jockey Ladies Yoga Jacket | Define Jacket | Settled (February 2026) |
| Spyder Women’s Yoga Jacket | Define Jacket | Settled (May 2026) |
| Hi-Tec Men’s Scuba Full Zip | Scuba Full-Zip Jacket | Still disputed as of mid-2026 |
Lululemon’s Scuba hoodie retails for roughly $118, its Define jacket for about $128, and its ABC pants around $128, according to the original complaint. The disputed Hi-Tec jacket at Costco was priced at $19.97.
What is trade dress infringement?
Trade dress infringement means one product’s overall look and feel copies another’s closely enough that shoppers could reasonably confuse the two. It covers more than logos or brand names; it can include silhouette, stitching details, pocket placement, and even signature color names.
Lululemon’s complaint specifically cites its “Tidewater Teal” color name and the term “Scuba” as protected trademark elements, in addition to the visual design of the garments themselves. The company also raised design patent claims, covering ornamental features of the Scuba hoodie specifically.
Trade dress cases are notoriously hard to win outright, since companies often settle rather than let a jury decide where “inspired by” ends and “infringing” begins. That pattern, four settlements and one contested product left, tracks with how most trade dress disputes actually resolve.
Key Takeaway: Four of five disputed products in this case have already settled, following the typical pattern for trade dress litigation.
Why did Lululemon sue Costco?
Lululemon sued Costco because it alleges the retailer sold lower-priced replicas of its bestselling apparel that could confuse consumers and damage its brand identity. The company said in a statement it “takes the responsibility of protecting and enforcing” its intellectual property “very seriously.”
The complaint argues Costco used manufacturers connected to popular branded products for its Kirkland Signature line without clearly disclosing that connection to shoppers, which Lululemon claims led some customers to believe Kirkland items came from the same source as the originals.
Lululemon’s filing also referenced the broader “dupe culture” trend, citing the hashtag “#LululemonDupes” and its own past “Dupe Swap” promotional events, where the company invited customers to trade counterfeit gear for authentic pieces.
How has Costco responded to the lawsuit?
Costco has not issued an extensive public statement on the specific allegations, but it formally contested the claims through a counterclaim filed in October 2025. Costco did not immediately respond to media requests for comment when the lawsuit was first filed in mid-2025.
The counterclaim, along with an amended answer, signals Costco is disputing at least some of Lululemon’s claims rather than simply agreeing to settle everything outright. That said, the pattern of settlements reached since February 2026 shows Costco has been willing to resolve most of the specific product disputes rather than litigate them through trial.
Manufacturer Jacques Moret Inc., which produced some of the disputed Danskin and Jockey products, separately intervened in the case and attempted to challenge two of Lululemon’s design patents covering the Scuba sweatshirt line, a dispute that was also resolved as part of the February 2026 settlement.
What court is handling the Lululemon Costco lawsuit?
The Lululemon Costco lawsuit is being handled in the U.S. District Court for the Central District of California, before Judge Fernando L. Aenlle-Rocha. The case has also been referred to a magistrate judge, A. Joel Richlin, for certain pretrial matters.
The court ordered both parties into private mediation through its Alternative Dispute Resolution (ADR) Procedure No. 3, with that order entered October 16, 2025. That mediation must be completed no later than July 31, 2026, according to the court’s docket.
No trial date has been publicly set. If mediation resolves the last remaining claim, the case is likely to conclude through another settlement stipulation, following the same path as the four prior product settlements.
Has Lululemon settled with Costco already?
Yes, Lululemon has settled four out of five disputed product lines with Costco as of May 2026, though the overall case has not been fully closed. Each settlement resolved claims tied to one specific product or brand rather than the case as a whole.
- February 2026: Settlement resolving claims against Jacques Moret Inc. and Costco-sold products under the Danskin and Jockey brands
- April 2026: Settlement resolving claims tied to Kirkland Signature pants
- May 2026: Settlement resolving trademark claims tied to the Spyder women’s yoga jacket
- Still unresolved: Claims tied to the Hi-Tec Men’s Scuba Full Zip jacket
All of these settlements were filed as joint stipulations in the public court record, not announced through press releases, and their financial terms have not been made public.
What happens if Lululemon wins the lawsuit?
If Lululemon wins on the remaining claim, the likely outcome would be an injunction stopping Costco from selling the disputed jacket, along with monetary damages paid to Lululemon. Neither outcome would create any payment to consumers who purchased the product.
Lululemon’s complaint sought three forms of relief: a jury trial, an order halting sales of the disputed items, and unspecified monetary damages. Not yet determined: whether the remaining claim will settle before the July 31, 2026 mediation deadline or proceed toward further litigation.
Given the pattern in this case so far, four settlements and no trial to date, a final resolution through mediation is a plausible outcome, though not guaranteed.
