False Intellectual Property claim - Listing deactivated

Hi there,

I’m a new seller.
After selling my first item for about 10 days (with good results), I received an intellectual property claim.

This was made by a suspicious hotmail email address.
The complaint was about a design patent number registered in the UK by a large German company which registered the same type of item but definitely different from ours.

We’re doing private label, we manufacture our products in China and we researched that the item we sell is not covered by copyright, patents etc.

We wrote to the claimant, as per Amazon suggestion, asking to retract the claim. They haven’t replied, we wrote again after 48 hours, they haven’t replied again.
We appealed the listing deactivation in the Account Performance tab, attaching the emails we sent to the claimant. A few hours later, Amazon reactivated our listing.

We kept selling for another week, still with good results, but today we got the same email address making the same claim (copy and paste of the previous one).
We appealed again with Amazon (still sending the emails we sent to the claimant).
The claimant hasn’t replied of course, Amazon instead replied that we need to provide further documents.

These documents are:

• A letter of authorization (LOA) or licensing agreement (LA) directly from the rights owner indicating that you are authorized to use their intellectual property. You can find the contact information of the rights owner in the listing deactivation communication you have received.
• An invoice directly from rights owner to indicate that your products are original and are purchased from the rights owner directly. You can find the contact information of the rights owner in the listing deactivation communication you have received.

We don’t have any of those, since we’re the manufacturer of the product and we do private label.

• Retraction from the rights owner to be sent to Amazon directly. You can find the contact information of the rights owner in the listing deactivation communication you have received.

The claimant is not replying so we can’t do anything about the above.

We suspect that the claim is coming from one of our competitors, not happy with the results a new seller is having.
The reasons why we suspect this are that the email address is a strange hotmail address (quite strange for a large German company - who has the patent for the similar product) and that nobody is replying to the emails we sent them (the claim is also written in very poor English).

Just to clarify, the German company’s patent clearly doesn’t apply to our product. However there are other sellers selling on Amazon the same exact product which is covered by the German company’s patent.

We do believe this is a false claim so we have now reported this fraud to the UK National Fraud & Cyber Crime Reporting Centre.

We’re only receiving pre-made replies from Amazon, nobody is actually reading our appeal.

It is incredible that anyone with an email address can cause a listing to be deactivated without having to demonstrate to Amazon the reasons for the claim. And Amazon doesn’t even read the claim, just deactivates the listing.

If anyone has any kind of suggestion, it would be much appreciated as this is causing us loss of sales and some headaches.

Thanks in advance for your time and attention.
