Summary. Both sides of an advertising dispute, in the order things happen.

Phase 1 — Capture, before any contact

  • Full-page screenshots of every web page, with URL and date visible.
  • Saved HTML and printed-to-PDF versions.
  • Recordings of broadcast and streaming spots, with air date, network, and daypart.
  • Print originals retained.
  • Purchase the product. Retain sealed, with packaging and receipt.
  • Retail display photographs, with store, date, and location.
  • Social and influencer posts, with account, date, and any disclosure language.
  • Sales decks, RFP responses, and one-pagers, with how each was received.
  • Archived versions showing when the claim first appeared and any changes.
  • Capture log naming the person, the date, and the method for each item.

Failure mode: sending a letter first and watching the claim quietly change.

Phase 2 — Characterize the claim

For each challenged statement:

  • Quote it exactly as it appears, in context.
  • Is it literally false on its face? (Deception is then presumed.)
  • Is it false by necessary implication — is the false message unavoidable?
  • Is it an establishment claim ("clinically proven," "tested to show," "studies demonstrate")? If so, you need only show the cited evidence does not establish it.
  • Is it an exclusivity claim ("only," "first," "sole," "patented")?
  • Is it comparative? Against which product, and which model?
  • Is it merely implied false? If so, budget for a survey.
  • Is it puffery — subjective, unmeasurable superiority? Screen these out honestly.
  • Does a puffing phrase sit next to a specific claim, supplying factual grounding?

Phase 3 — Test the remaining elements

  • Materiality: would this influence a purchasing decision? Inherent quality, or peripheral?
  • Is there evidence the advertiser's own research says the claim drives purchase?
  • Interstate commerce: satisfied.
  • Standing under Lexmark:
    • Injury to a commercial interest in reputation or sales (zone of interests)
    • Proximate cause: deception caused consumers to withhold trade from you
    • Note: direct competition is not required; remoteness still defeats
  • Your own advertising audited for the same claim — unclean hands.
  • Test both products under a common protocol, at an independent laboratory.

Phase 4 — Choose the forum

  • What do you actually want: the claim stopped, or money?
  • How long will the campaign run? A twelve-week flight and a two-year campaign call for different routes.
Objective Route
Stop a broadcast spot fast Network clearance challenge
Stop a marketplace listing Platform policy complaint
Substantiation-weak claim, months available National Advertising Division
Immediate cessation Preliminary injunction
Money Federal litigation
Preserve the relationship Demand letter
  • Confirm you cannot run the self-regulatory route and litigate; the forum generally closes a case on filing suit.
  • Assess counter-challenge exposure before initiating anywhere.

Phase 5 — Preliminary injunction

  • Move within weeks of discovery. Delay rebuts the presumption of irreparable harm.
  • Four factors under Winter and Rule 65 addressed.
  • Lead with literal falsity where available.
  • Technical expert declaration on falsity or on why the cited studies do not establish the claim.
  • Business declaration on injury: lost accounts, price pressure, customer inquiries.
  • Capture declaration authenticating each advertisement.
  • Position on the Rule 65(c) bond, with supporting evidence.
  • Proposed order drafted so a compliance officer could follow it — specific claims, specific media.
  • Address any voluntary cessation and why recurrence is likely.

Phase 6 — Substantiation discovery

  • All documents constituting or referring to substantiation for each claim.
  • Testing protocols, including drafts and revisions.
  • Raw data, not summaries.
  • Identity and qualifications of testers and supervisors.
  • Comparison products used: model numbers, purchase dates, condition.
  • All tests that did not support the claim.
  • Consumer perception research on message takeaway.
  • Marketing and media plans; spend behind the claim.
  • Communications with testing vendors and research firms.
  • Internal approvals, including legal and regulatory review (expect privilege fights).
  • Sales data before, during, and after the campaign.
  • All prior versions of the claim and reasons for changes.

Phase 7 — Survey (implied falsity only)

Building it

  • Expert retained before the instrument is designed.
  • Universe = actual purchasing population; screeners defensible.
  • Stimulus = the advertisement as it ran, in context.
  • Control cell included.
  • Open-ended questions before closed; nothing leading.
  • Order and rotation addressed.
  • Net deception calculated and reported.
  • Instrument, raw data, field reports, and coding instructions preserved and producible.

Attacking it

  • Universe over- or under-inclusive?
  • Artificial stimulus?
  • Control missing or inadequate?
  • Leading questions or order effects?
  • Sample size and representativeness?
  • Coding of open-ends?
  • Net deception below the persuasive range?
  • Motion filed under Rule 702 on methodology, not execution.

Phase 8 — Remedies

  • Injunction sought under 15 U.S.C. § 1116; presumption of irreparable harm invoked.
  • Defendant's profits under 15 U.S.C. § 1117 — no willfulness precondition after Romag; prove sales, defendant proves deductions.
  • Lost profits: accounts lost, bids lost, price concessions, econometric support.
  • Corrective advertising cost quantified.
  • Enhancement considered.
  • Fees under the exceptional-case standard — assessed in both directions.
  • Client advised honestly that damages proof is difficult.

Phase 9 — The defendant's response

  • Preserve immediately, including the substantiation file and every claim version.
  • Read the substantiation file honestly. Does it support the claim as consumers read it?
  • Does the protocol match the claim's conditions?
  • Was the comparison against a currently marketed competitor product?
  • Re-characterize: can the case be pushed into implied falsity, requiring a survey?
  • Attack standing and materiality.
  • Raise puffery only where it genuinely fits.
  • Check the plaintiff's own advertising for the same claim.
  • Evaluate a counterclaim.
  • Evaluate modification. A word change that removes exposure while preserving the campaign is usually the right business answer.
  • Contest the bond amount with evidence.

Phase 10 — Prevention program

  • Claim intake form: exact wording, medium, meaning, supporting evidence.
  • Tiered review by claim type (puffery / feature / performance / establishment / comparative / health and safety).
  • Rule one: the claim and the test must match.
  • Rule two: comparative claims require side-by-side testing of currently marketed products.
  • Rule three: retain the tests that did not support the claim.
  • Substantiation file assembled before the claim runs, and dated.
  • Re-verification calendared for comparative claims.
  • Channel review: build to the strictest channel's standard.
  • Influencer contracts require approved claim language; monitoring in place per 16 C.F.R. Part 255.
  • Annual audit of live claims against current substantiation.

Phase 11 — Settlement terms

  • Specific claim prohibitions, not a general ban on false advertising.
  • Realistic transition period for print, packaging, and placed creative.
  • A substantiation standard for future claims — the most valuable term available.
  • Notice-and-cure mechanism for future disputes.
  • Corrective communication where warranted.
  • Liquidated damages or a stipulated injunction for breach.
  • Mutual releases scoped to the claims at issue.
  • Consent judgment considered where recurrence risk is real.
