I contacted Amazon Sellers' Lawyer to help me resolve an IP issue and talked to Brett. He was easily accessible (their website chat is great) and gave me clear and thorough advice. After talking for a bit I realized I would not need his service, but it was incredibly generous of him to give me honest, free guidance.
Most places won't even talk to you without a fee. Plus it's hard to know if you even need their services.
Because of Brett's help, I highly recommend these guys and will come back here for any future Amazon legal issues.
