What specific action must a seller take to regain control over a product listing hijacked by unauthorized sellers, assuming they are Brand Registered?

When a Brand Registered seller discovers their product listing has been hijacked by unauthorized sellers, the immediate specific action is to report the violation to Amazon through the 'Report a Violation' tool within their Brand Registry account. This report should include detailed evidence of the infringement, such as proof that the unauthorized sellers are not offering genuine products (e.g., differences in packaging, product quality, or features), or that they are using the brand's trademark without permission. The seller should provide clear evidence that they are the legitimate brand owner and that the other sellers' offerings are counterfeit or infringing. If the unauthorized sellers are altering the product details or content of the listing, this should also be documented and included in the report. Accurate and comprehensive reporting is crucial for Amazon to investigate the claim effectively and take appropriate action, which may include removing the unauthorized sellers from the listing and restoring control to the rightful brand owner.
