How a matter moves02

Evidence first. Then the proportionate response.

Step 01

Preserve.

Secure the evidence before it moves.

Counterfeit and copycat listings can change or disappear without warning. The first task in any enforcement matter is a usable record: captures of the listings, the sellers, and the brand’s own rights documentation.

What preservation looks like depends on the platform, the asserted right, and where the matter may go next.

Step 02

Assess.

Read the situation, not just the listing.

With the record in hand, counsel evaluates the rights involved, the recurring sellers, the platforms, and the business harm an enforcement plan must address.

The assessment weighs cost, urgency, and likely impact across the available responses — platform reports, escalation, demand letters, border recordation, and federal litigation.

Step 03

Act.

Take the proportionate step.

Marketplace reporting tools may be an appropriate starting point for individual listings. Where they are insufficient, escalation paths, a properly framed demand, or federal litigation may provide additional options.

Where you start depends on your rights, your evidence, and your objectives. Every matter is different; available claims, remedies, timing, and cost depend on the facts, the rights at issue, the other parties, and the forum.

Counterfeit & marketplace enforcement03

The enforcement ladder: what actually works, and when.

01Self-serve takedownsMarketplace reporting tools may be an appropriate starting point for individual listings. The right first step depends on the available rights documentation and evidence.

02Platform escalationIf an initial platform report does not resolve the issue, available escalation paths depend on the platform, the asserted right, and the supporting record.

03Test buys and demand lettersA properly framed demand can resolve a matter without a filing — or build the evidentiary record for one. Where it would add proof, counsel may also consider a documented test buy.

04Border enforcementRecording a registered trademark with U.S. Customs and Border Protection lets CBP detain and seize counterfeit goods at the border.

05Federal litigationWhen platform and non-litigation options are insufficient, federal litigation may provide additional options. One mechanism sometimes used against multiple online sellers is known as a “Schedule A” case — one tool among several, suitable in some situations and unnecessary in others.

Where you start depends on your rights, your evidence, and your objectives.
