Someone Copying Your Patented Product on Amazon? How to Use a TRO to Stop Them

Someone Copying Your Patented Product on Amazon? How to Use a TRO to Stop Them

If someone is copying your patented product on Amazon, owning the patent isn’t enough. You have to take them to court to stop them — and most sellers never do, usually because they don’t know the process exists or how it works. Here is a real case that shows, step by step, what enforcing a patent actually looks like.

Our client had spent years selling a product they developed and patented in the United States. It sold well and the brand became known. Then copycats appeared: multiple sellers listing near-identical knockoffs, some using the exact patented design. Those listings split the client’s sales and damaged the brand — and they kept multiplying. The client had the legal right to stop this the entire time but had never acted on it. So we did.

Step 1: Build the evidence

Before going to court, we documented each infringing listing, saved the product pages so the sellers couldn’t quietly delete them, and compared each knockoff against the patent to show clearly where it copied the protected design. This evidence is what the court needs in order to act, and it is the foundation everything else rests on.

Step 2: File the lawsuit and request a TRO

A TRO (Temporary Restraining Order) is an emergency court order. We filed suit in U.S. federal court against the infringing sellers and, at the same time, asked the judge for the TRO. In these cases the judge typically grants it without warning the other side first — that’s deliberate, so the infringers can’t move their money out before the order lands.

Step 3: The freeze does the work

Once the judge signs the order, Amazon enforces it: the infringing sellers’ funds are frozen, their listings come down, and their stores are restricted from operating. Amazon doesn’t second-guess the order — it acts on the court’s instruction. This is the part most sellers don’t realize: the patent holder isn’t asking Amazon to take their side, they’re handing Amazon a court order Amazon has to follow.

Step 4: Settle from a position of strength

Now the infringers are the ones under pressure — their cash is locked and they can’t sell. That is what brings them to the table on the patent holder’s terms. We negotiated directly with each side, so our client never had to contact a single infringer themselves.

The result

The court granted the TRO, the infringing accounts were locked down, and the matter was resolved quickly. Our client went back to running their business instead of policing copycats one listing at a time.

The lesson for cross-border sellers

A patent only does something when you enforce it. The filing protects nothing on its own — the court case is what actually stops the copying. And the longer you wait, the more the knockoffs take over your sales, your brand, and your market.

If your product is being copied or your design cloned overseas, the time to act is before the copies become the market.
