Advertising Expert Witnesses

Advertising disputes arise wherever a company's marketing claims, brand messaging, or promotional practices become contested by a competitor, regulator, or business partner. Litigation frequently involves false or deceptive advertising claims under the Lanham Act, disputes over comparative advertising and brand claims, and disagreements about whether marketing communications create consumer confusion actionable under trademark or unfair competition law. Advertising agency contract disputes, including disagreements over campaign performance, media placement, and creative deliverables, can also generate commercial litigation between businesses and their marketing partners. Because advertising spans traditional, digital, and social media channels, disputes increasingly involve questions about online advertising practices, targeting, and disclosure requirements. At the center of most matters is whether an advertising claim or practice met the standards the industry and applicable law require.

An advertising expert helps counsel evaluate whether a marketing claim, campaign, or agency engagement met accepted industry standards and legal requirements. In false advertising and unfair competition disputes, experts can assess whether a claim is likely to mislead consumers, drawing on marketing research and survey methodology. In agency contract disputes, experts can evaluate whether a campaign's creative, media planning, and execution met the deliverables and standards the parties agreed to. In digital and social media matters, experts with online advertising backgrounds can address platform-specific practices, targeting methodologies, and disclosure requirements. This analysis gives litigators the industry-specific grounding needed to argue advertising claims and defenses credibly.

Because advertising expertise spans disciplines from consumer behavior and market research to digital marketing and advertising law, matching an expert's specific background to the case is essential. The advertising professionals Round Table Group can provide include scholars from major universities and practitioners who have worked at leading agencies and Fortune 500 companies, with experience spanning brand strategy, media planning, consumer research, and advertising regulation, and several have testified on matters involving deceptive advertising and trademark confusion. We've completed more than 75,000 expert searches for litigators, and we apply that experience to match counsel with an advertising expert whose specific background fits the case. Let us help you find the right advertising expert for your case by calling us at (202) 908-4500.

Kinds of Cases We Work On

Round Table Group helps our clients find a wide variety of Advertising expert witnesses for cases like:

01

Comparative Ad Claims Spark Lanham Act Suit.

A national consumer products company sued a direct competitor under the Lanham Act, alleging its national ad campaign made unsubstantiated comparative performance claims that caused the plaintiff to lose shelf space and market share across a major retail channel. We identified experts with experience in advertising claims substantiation, comparative performance testing methodology, and Lanham Act false advertising analysis. The underlying study relied on had tested a different product formulation than the one actually sold during the campaign, undermining the claim's substantiation, supporting a settlement requiring the campaign's withdrawal and corrective advertising.
02

Terminated Agency Disputes Owed Termination Fees.

An advertising agency sued its former client after being terminated as agency of record mid-contract, alleging the client owed a contractually specified termination fee based on projected billings for the remainder of the term. We identified experts with experience in advertising agency compensation structures, media commission accounting, and agency-of-record contract analysis. The client's proposed calculation improperly excluded a category of media commission revenue the agreement's own billings definition included, supporting a settlement recovering the disputed fee.
03

Bot Traffic Inflated Programmatic Ad Billings.

A national retailer sued its programmatic advertising platform, alleging a substantial share of billed ad impressions across a major campaign came from non-human bot traffic rather than genuine consumer views. We identified experts with experience in ad tech fraud detection, programmatic impression verification, and digital advertising traffic analysis. A meaningful share of billed impressions on several publisher placements exhibited traffic patterns consistent with automated bot activity, supporting a settlement recovering a portion of the disputed ad spend.
04

Influencer Agency Blamed for Disclosure Failures.

A consumer brand sued the influencer marketing agency it had engaged to manage a large sponsored content campaign, alleging its failure to ensure proper sponsorship disclosure across a substantial share of posts exposed the brand to regulatory scrutiny and reputational harm. We identified experts with experience in advertising disclosure compliance, influencer marketing campaign auditing, and sponsored content regulatory standards. A meaningful share of sampled posts lacked adequate disclosure despite the agency's compliance checklist indicating review and approval, supporting a settlement covering compliance remediation costs.
05

Co-Op Ad Fund Reimbursement Dispute Erupts.

A national manufacturer sued a regional dealer group, alleging the dealers had submitted co-op advertising fund reimbursement claims for local campaigns that did not comply with the manufacturer's brand guidelines and media mix requirements. We identified experts with experience in co-op advertising program compliance, brand guideline auditing, and media placement eligibility review. A substantial share of sampled claims involved media placements and creative outside the program's eligible categories, supporting a settlement requiring repayment of the improperly claimed funds.
06

Sponsor Says Activation Value Was Overstated.

A beverage company sued a professional sports league over a multi-year sponsorship agreement, alleging the promised media exposure and activation value fell substantially short of the impression and engagement metrics projected during negotiation. We identified experts with experience in sponsorship valuation methodology, media exposure measurement, and sports marketing activation analysis. Actual broadcast and digital impressions fell well below the projected levels across most measured touchpoints, supporting a settlement reducing the sponsorship fee for the remaining term.
07

Buyer Says Agency's Client Retention Was Inflated.

A holding company sued the sellers of an independent advertising agency it had acquired, alleging client retention and recurring billing figures presented during diligence had been substantially inflated relative to actual post-acquisition performance. We identified experts with experience in advertising agency valuation, client retention data reconstruction, and M&A financial diligence review. Reported retention figures had included several large client relationships already in a documented review period before closing, absent from the diligence materials, supporting a substantial post-closing purchase price adjustment.
08

Media Buyer's Hidden Rebates Draw Lawsuit.

A national advertiser sued its media buying agency, alleging it had accepted undisclosed volume rebates from media vendors that should have been passed through under their agency-of-record agreement's transparency provisions. We identified experts with experience in media buying transparency standards, vendor rebate accounting, and agency fiduciary compliance analysis. The agency had retained a meaningful share of vendor rebates tied directly to the advertiser's own media spend, inconsistent with the pass-through requirement, supporting a settlement recovering the retained rebates.
09

Billboard Company Missed Its Impression Guarantee.

An advertiser sued an out-of-home advertising company, alleging a series of billboard placements failed to deliver the contractually guaranteed daily traffic impression counts across a multi-month regional campaign. We identified experts with experience in out-of-home media measurement, traffic impression methodology, and outdoor advertising performance auditing. The counts had relied on outdated regional traffic studies that overstated actual vehicle volume at several locations, supporting a settlement providing make-good placements and partial fee credits.
10

Network's Ratings Miss Triggers Make-Good Fight.

A national advertiser sued a broadcast television network, alleging a major ad buy tied to guaranteed audience ratings for a marquee programming slot fell well short of the guarantee, and the network's proposed make-good placements failed to adequately compensate for the shortfall. We identified experts with experience in broadcast media measurement, audience ratings analysis, and make-good placement valuation. The proposed make-good placements delivered audiences with meaningfully different demographic composition than the original guarantee specified, supporting a settlement providing additional correctly targeted inventory.
