Have you received a patent infringement report from Coupang and have your sales stopped?
A sales suspension is more than a removed listing. It can affect revenue, advertising rankings, reviews, and account operations.
Patent complaints require a claim-by-claim comparison with the actual product. Similarity in appearance alone is insufficient; the elements of the asserted claims must be analyzed.
IPLEX IP Law Firm assists with claim analysis, product-structure comparisons, non-infringement responses, patent attorney opinions, and defenses based on freely usable prior-art technology.
If you have received a report of a Coupang patent infringement.
If you receive an intellectual property rights report from Coupang, you must first identify the type of rights that have been reported.
Whether it is a trademark infringement, a design right infringement, a copyright infringement, or a patent infringement, the response will vary.
The key to patent infringement is patent claims.
The relevant comparison is between the patent claims and the accused product, rather than simply between the seller's product and the complainant's product.
After a patent-related sales suspension, promptly review the following:
- The reported patent number
- Patent owner and filing date
- The contents of the granted patent claims
- Essential elements of the claims
- The Real Structure of Selling Products
- Patent Claims and Differences in Selling Products
- Disclosures predating the patent filing
- Potential defenses based on freely usable prior-art technology
How IPLEX IP Law Firm works
1. The patent claim analysis.
A patent infringement judgment begins with a patent claim.
The IPLEX IP Law Firm breaks down the patent claims of the reported registration patent by component and examines whether each component is present in the actual sale product.
If the product looks similar, but the core component of the patent claim is not in the sale, the patent claim may not be infringing.
2. Check the actual structure of the product for sale
Product listing images alone may be insufficient for an accurate infringement analysis.
In patent cases, the internal structure, the coupling method, the way it works, and the relationship between the parts are often an issue.
IPLEX reviews product photographs, disassembly images, structural descriptions, and videos to identify differences between the claimed features and the actual product.
3. Preparing a feature comparison chart
Platform reviewers need evidence that allows them to understand the issues quickly.
The IPLEX IP Law Firm creates a one-on-one comparison of patent claims and sales products.
Corresponding configurations are clearly marked, and non-corresponding configurations are presented specifically through photos and descriptions.
4. Preparing a non-infringement response
Simply saying 'there is no infringement' is insufficient.
The response should explain non-infringement by reference to the patent claims and the product's actual features.
IPLEX prepares a clear non-infringement response suited to Coupang's review process.
5. Patent attorney's opinion
Infringement of patent rights is an area that requires professional judgment.
Patent attorney opinions can play an important role because patent claim analysis, component contrast, product structure analysis, and prior art review are required.
The IPLEX IP Law Firm systematically explains that the products sold do not fall under the protection of the registered patent.
6. Review of prior-art defenses
If an identical or substantially identical product was disclosed before the patent filing date, consider whether a defense based on freely usable prior-art technology is available.
Earlier sales listings, user reviews, product photographs, and sales records may establish relevant public disclosures.
The IPLEX IP Law Firm reviews the public data prior to the patent filing date and reflects it in the Coupang statement and patent attorney opinion.
Coupang patent infringement report case
PILLOW STRUCTURE PATENT
The client received a report of patent infringement while selling pillow products in Coupang and received a notice of suspension.
The complainant relied on a registered patent for a pillow structure. Coupang requested a response and supporting evidence from the seller.
IPLEX IP Law Firm first analyzed the patent claims of the registration patent. As a result, the key to the patent lies not just in the bending pillow, but in the concrete joining structure of the inner joint.
In particular, the patent claim required the following configuration.
- Structure in which the head is rotated to the body part
- Separate coupling for head and body parts
However, the actual sales products were connected by a simple attachment, and there were no rotatable insertion structures and couplings required by the patent claim.
As a result, the product does not meet all components of the registered patent claim.
Evidence showed that an identical or substantially identical product had been sold on overseas platforms before the patent filing date. IPLEX also considered a prior-art defense based on that evidence.
IPLEX submitted a complaint response and a patent attorney's opinion to Coupang explaining why the product was argued to fall outside the patent's scope.
Common issues in responding to Coupang patent complaints
If the product looks similar.
The patent infringement is not due to the similarity. All required components of the patent claim must be present in the actual product.
If I compare only my products with the products of the complainant
In the patent case, the comparison criteria are not the actual product of the complainant, but the patent claim of the registration. It may not be enough to claim that it is different from the product of the complainant.
If you only respond to detail images
Internal structure may be critical in a patent case. Prepare actual product photographs, disassembly photographs, and explanations of the structure.
Missing the response deadline
As time goes on, the sales stop will result in loss. You must submit a statement and evidence within the specified time frame.
If you have an emotional complaint.
In Coupang response procedures, objective data and legal explanations are more important than emotional ones. Patent claims analysis, composition sheet, product photos, and patent attorney opinions are required.
The Coupang Sales Suspension Response Process
Step 1. Consultation and review of the suspension notice
Review the complaint notice, asserted rights, product information, and suspension status.
Step 2. Review of the asserted patent
View the patent number, patent claim , application date, date of registration, and rightholder information and analyze the scope of protection of the patent right.
Step three. Sales Product Structure Analysis
Check the actual structure of the products for sale, the internal parts, how they are combined, and how they work.
Step 4. Comparison of claims with the product
Compare each component of the patent claim with the sale product one-on-one and review the breach.
Step 5. Search for earlier disclosures
Verify that the same or similar product has been published before the patent application.
Step 6. Response and patent attorney's opinion
Prepare a response to the IP complaint and a separate patent attorney's opinion.
Step 7. Coupang submission and follow-up response
Submit the response to Coupang and address follow-up questions or requests for additional evidence.

Frequently Asked Questions
Can sales resume after a patent complaint?
That depends on the case. Missing claim elements or a valid defense based on pre-filing prior art may support a request to resume sales.
Does a similar appearance establish patent infringement?
No. Patent infringement depends on the claims, not appearance alone. Literal infringement generally requires every claim element; potential infringement under the doctrine of equivalents must also be considered.
What data should I submit to Coupang?
Relevant materials may include a complaint response, product photographs, structural explanations, a claim comparison chart, a patent attorney's opinion, and evidence of earlier disclosures.
Is a patent attorney's opinion always required?
Not always, but it can strengthen a response where technical claim analysis and legal assessment are needed.
Can overseas sales listings help?
Yes. Listings showing relevant products publicly sold before the patent filing date may support a prior-art defense, provided their content and dates can be established.

Patent complaints require prompt and accurate responses.
A response that lacks claim analysis, product-structure evidence, or supporting documents may fail to establish grounds for resuming sales.
IPLEX assists with claim analysis, product comparisons, prior-art defenses, complaint responses, and patent attorney opinions.
