Giri Prasad of SalesDuo: Proactive Measures for Combating Unauthorized Amazon Sellers and Defending Your Brand

As an Amazon Seller, maintaining control over your brand and authorized distribution channels is crucial for success. Unfortunately, unauthorized third-party (3P) sellers can pose a significant challenge, diluting your brand’s reputation and impacting your sales. While removing unauthorized sellers can be complex, it is possible to take action within Amazon’s policies and guidelines. In this guide, we’ll provide you with a step-by-step approach to remove unauthorized 3P sellers on Amazon.

Step 1: Verify the unauthorized status

The first step is to ensure that the seller is genuinely unauthorized to sell your products on Amazon. Review your authorized seller list and cross-reference it with the seller in question. If they are not authorized, proceed to the next step.

Step 2: Document evidence

Since concrete evidence may be limited to what you observe on Amazon, the key focus should be on gathering information through purchasing the product from the unauthorized seller. This will provide you with tangible evidence to support your case.

  1. Place an order: Purchase the product in question directly from the unauthorized seller on Amazon. Make sure to keep a record of the order ID or any order-related documentation provided by Amazon.
  2. Receive the product: Once the product arrives, carefully inspect it and compare it to your genuine products. Look for any discrepancies in packaging, labeling, quality, or other possible identifiers that may indicate the product is counterfeit.
  3. Take detailed photos: Capture high-quality images of both the counterfeit product and your genuine product for comparison. Highlight any notable differences, such as variations in packaging, logos, or product features. These photos will serve as visual evidence to support your case.
  4. Retain order-related documentation: Keep all relevant documentation related to the purchase, such as order confirmation emails, invoices, shipping labels, and any communication with the unauthorized seller. These documents will further validate your claim.
  5. Submit evidence to Amazon: Contact Amazon’s Brand Registry team through your account and provide them with the evidence you have gathered. Include the order ID, detailed photos of the counterfeit product, and any other pertinent information. Explain that you have purchased the product from an unauthorized seller and have identified it as a potential counterfeit.

Step 3: If it is Genuine, Send a Cease and Desist (C&D) letter

If you have purchased the product from an unauthorized third-party seller on Amazon and determined that it is a genuine item, you may consider sending a Cease and Desist (C&D) letter to the seller. A C&D letter is a formal legal notice that demands the recipient to immediately stop engaging in certain activities, such as unauthorized selling of your products. In this case, the C&D letter would serve as a warning to the unauthorized seller, notifying them of their infringement on your exclusive rights. Clearly state in the letter that their unauthorized selling violates your intellectual property rights and request that they cease all sales and remove the listings from Amazon immediately. Provide evidence of your ownership of the brand or product and include details of the unauthorized seller’s activities, such as the ASINs to which they offer and order information. Make it clear that legal action may be pursued if they fail to comply with your demands. It is advisable to consult with a lawyer specializing in intellectual property law to draft and send the C&D letter to ensure its effectiveness and adherence to legal requirements.

Step 4: Monitor the situation

After reporting the issue to Amazon and sending a Cease and Desist (C&D) letter to the unauthorized seller, it’s important to remain vigilant and continue monitoring the activities on your product. In most cases, Amazon will remove it if we can prove the item to be counterfeit. Hence keeping a close eye on your listings and review for any new violations that may occur. Consistent monitoring demonstrates your ongoing commitment to protecting your brand and can help reinforce your position in dealing with unauthorized sellers.

Step 5: Protecting Your Patent on Amazon: Ensuring Continued Compliance after Seller Removal

To ensure that the product is not sold in the market using your patent after removing the seller from Amazon, it is crucial to take swift and effective legal action, even considering that the infringing party may have their own attorneys. Start by consulting with an experienced intellectual property attorney who specializes in patent law. They will provide valuable guidance and help you develop a strategy to protect your patent rights. Your attorney can draft a strong Cease and Desist (C&D) letter, asserting your patent rights, presenting evidence of infringement, and demanding an immediate cessation of the sale of infringing products. This formal notice serves as a strong warning and may prompt compliance. However, if the infringing party persists, your attorney can advise on the appropriate next steps, which may include filing a lawsuit to enforce your patent rights and prevent further infringement in the market. Having a skilled attorney by your side will ensure that your interests are well-represented and increase your chances of successfully protecting your patent.

Step 6: Utilize the Amazon Transparency Program

The Amazon Transparency Program is an effective tool for brand owners to further protect their products from unauthorized sellers. By enrolling your products in this program, each unit is assigned a unique Transparency code that allows you to track and authenticate individual products throughout the supply chain. This helps ensure that only genuine products reach the customers, reducing the risk of counterfeits and unauthorized sales. By leveraging the Amazon Transparency Program, you can enhance the security and authenticity of your products on the platform.
