You Got an APEX Notice. You Have Three Options and One of Them Is a Trap.

Accept, opt out, or participate. Each door leads somewhere different, the deadline is short, and the one that sounds like relief is often the one that invites a lawsuit.

By Kenneth G. Eade, CA Bar No. 93774, with Michael S. Brandt, USPTO Reg. No. 39119 · August 2, 2026

An APEX notice arrives without warning and gives you a short window to decide something consequential. Most sellers read it once, feel the deadline, and pick whichever option seems least frightening. That is the wrong basis for the decision, because the three options don't differ in difficulty — they differ in where they leave you six months from now.

What APEX actually is

Amazon Patent Evaluation Express is a private, fast-track proceeding. A utility patent owner alleges that your product infringes. A neutral third-party evaluator — typically a patent attorney — reviews written submissions from both sides and decides whether the accused listing infringes the asserted claims.

Three things it is not. It is not a court proceeding. It does not adjudicate validity — the evaluator takes the patent as issued and asks only about infringement. And it does not produce a binding judgment between the parties. What it does determine, quite decisively, is whether your listing stays up.

Both sides post a deposit, and the prevailing side generally gets theirs back. Check the current amount and the exact response deadline in the notice you received rather than relying on any figure you read online, including here — Amazon adjusts the program.

The deadline runs from the date of the notice, not from the date you noticed it. Sellers lose listings to inbox triage more often than to the merits. Find the response date the moment the notice arrives, before you decide anything else.

Option one: do nothing

Technically not an option, but it is what happens most often, so it belongs on the list. The accused listings generally come down by default. No evaluator considers the merits. No deposit is at risk because none was posted.

The trap here is that doing nothing feels like a neutral holding position — as if the matter stays open and you can address it later. It doesn't. The listing is gone, and the patent owner has learned that filing an APEX against you works.

Option two: opt out — the one that's usually a trap

Opting out removes the dispute from Amazon's process. Sellers reach for it because it sounds like escaping an unfair private tribunal. Two things they miss:

It does not preserve your listing. Opting out of the evaluation does not resolve the underlying complaint in your favor.

It does not make the patent owner go away. It removes the cheap, fast, contained forum and leaves the expensive, slow, uncontained one — federal court. A patent owner who was willing to spend a modest deposit on an evaluation may now be looking at a seller who has declined the low-cost process, and some read that as an invitation.

Opting out is a legitimate strategic choice in specific circumstances: where you are prepared to defend the patent claim in federal court, where a declaratory judgment action is contemplated, or where the patent is weak enough that a broader challenge to validity makes sense. Those are deliberate decisions made with counsel who has read the patent.

It is a poor choice made simply to dodge a deadline or avoid a deposit.

Option three: participate

You post the deposit and submit a written response arguing non-infringement. The evaluator considers both submissions and decides.

For a seller with a genuine non-infringement position, this is frequently the best available option: it is fast, contained, far cheaper than litigation, and a favorable evaluation resolves the listing problem directly.

The catch is what "a genuine non-infringement position" means, because it is narrower than sellers expect.

What the evaluator is actually asking

One question: does the accused product contain every element of at least one asserted claim, as those claim terms are properly construed?

That is it. Which means the arguments sellers instinctively reach for are, in this forum, entirely beside the point:

• "My product looks different" — irrelevant unless the difference maps onto a claim element
• "I bought it from a legitimate supplier" — sourcing is not a defense to patent infringement
• "This patent shouldn't have issued" — validity is not before the evaluator
• "They're using this to knock out competitors" — motive is not an element
• "I've been selling this for years" — prior use by you is not a defense here

A response built on any of those loses, not because the evaluator is unfair, but because it never addressed the question. Winning requires reading the claims, construing the terms, and showing that at least one element is missing from your product. That is patent work, and it is why the response needs a patent attorney rather than an appeal consultant.

Winning APEX doesn't kill the patent

Worth internalizing before you celebrate. A favorable evaluation means the evaluator concluded your product likely doesn't infringe. The patent remains in force. The owner can assert it against your next product, against a modified version, or in federal court where validity is on the table.

Conversely, losing APEX does not mean the patent has been adjudicated valid — you simply lost an infringement assessment.

Where the underlying patent is genuinely weak — where the claimed invention was already in the market, or the prior art is obvious — the durable fix is challenging validity at the USPTO through reexamination. Different proceeding, different economics, different timeline. But if the same patent is being asserted against you repeatedly, or against a whole category you sell in, winning APEX each time is treating symptoms.

What to do in the first 48 hours

Find the deadline. Everything else is secondary.

Pull the patent. Not the complaint — the actual patent, and specifically the claims. The independent claims are where the analysis starts.

Identify the accused ASINs precisely. Patent owners sometimes sweep in listings that don't practice the claim at all.

Get a claim chart before you decide. Element-by-element, claim language against your product. That chart tells you whether you have a non-infringement position — and therefore which of the three doors makes sense. Deciding before you have it is guessing.

Don't modify the listing hoping it goes away. It doesn't, and it can complicate the record.

Frequently asked

What is Amazon APEX?

A private, fast-track proceeding in which a utility patent owner alleges infringement, a neutral third-party evaluator reviews written submissions from both sides, and the evaluator decides whether the accused listing infringes. It is not a court proceeding, does not adjudicate validity, and does not create a binding judgment — but it determines whether the listing stays up.

What happens if I ignore an APEX notice?

The accused listings are generally removed by default. Ignoring is not a neutral choice and is not the same as opting out. The deadline runs from the date of the notice, not from when you noticed it, and a seller who misses it has usually lost the listing without the merits ever being considered.

Should I opt out of APEX?

Only deliberately. Opting out removes the dispute from Amazon's process but does not preserve the listing and does not make the patent owner go away — it substitutes federal court for a cheap contained forum. It is reasonable where you're prepared to litigate, where a declaratory judgment action is contemplated, or where the patent warrants a validity challenge. It is a poor choice made to avoid a deadline or a deposit.

Does winning APEX mean the patent is invalid?

No. The evaluator decides only whether your product likely infringes the asserted claims. Validity isn't before them. You can win on non-infringement and face the same patent again, and losing does not mean the patent was adjudicated valid. Where the patent is genuinely weak, reexamination at the USPTO addresses validity — a different proceeding entirely.

Why does an APEX response need a patent attorney?

Because the evaluation turns on claim construction and element-by-element comparison, not policy argument. Arguing that your product is different, that you sourced it legitimately, or that the complaint is unfair does not engage the question the evaluator is asking. The accused product has to be assessed against the claim language, and that is patent work.
