Common Questions

What clients ask us first

Amazon removed my listing for IP infringement. What can I do?

Options include asking the rights owner to retract the complaint, showing the goods are authentic, or submitting evidence that your product does not infringe — often supported by an attorney's non-infringement letter.

What is a non-infringement letter?

A letter from a U.S. attorney analyzing the asserted right and explaining why your product does not infringe it. Platforms often give it significant weight in an appeal.

Can a competitor misuse IP complaints against me?

It happens. If a complaint is unfounded, we can respond to the platform and, where appropriate, address the complainant directly.

Someone is copying my product. How do I take them down?

If you hold a registered trademark, copyright or patent, we can file complaints through the platform's reporting tools and, if needed, send a cease-and-desist letter.
