Capabilities & Evidence Framework

Hard Litigation Questions We Solve in Discovery & Trial

Trial counsel retains BGX Solutions to translate complex paid search ad auctions, algorithmic attribution models, impression data, and DTC operational economics into clear, defensible evidence for judges and juries.

Trademark & Keyword Bidding

"Did a competitor's paid search keyword bidding & ad copy create likelihood of confusion under legal standards?"

Forensic analysis of Google Ads and Bing Ads keyword target bidding, impression share loss, ad copy messaging, negative keyword hygiene, and organic SERP displacement to establish intentional consumer diversion or confusion under Polaroid / Sleekcraft factors.

Damages Practice Focus
Financial Damages & Economics

"How do raw paid media impressions, search clicks & DTC unit economics translate into defensible damages?"

Bridging the gap between digital marketing metrics and financial damages. We construct empirical impression-to-revenue conversion models to quantify unjust enrichment or lost profits, and conduct comprehensive, end-to-end ("soup-to-nuts") cost validations for standalone Direct-to-Consumer (DTC) e-commerce businesses, including CAC, technology stack hosting, fulfillment, and media scaling friction.

Forensic Analytics & Audits

"Can GA4 logs, ad tech tracking infrastructure & multi-touch attribution substantiate web traffic integrity?"

Deep-dive audit of Google Analytics 4 (GA4), tag management systems, server logs, ad server parameters, and multi-touch attribution algorithms to verify actual web traffic volume, referral sources, conversion integrity, and lost profits.

E-Commerce & Digital Shelf

"How do e-commerce algorithms, digital shelf mechanics & target audience overlap drive reverse confusion?"

Evaluating Amazon / retail platform search indexing, digital catalog placement, category taxonomy encroachment, and target consumer demographic overlap in high-stakes reverse trademark confusion and brand dilution disputes.

Litigation Practice FAQ

Frequently Asked Questions by Trial Counsel

Clear answers regarding expert retention, damages team collaboration, and procedural experience.

Do you collaborate with economic damages teams and forensic accountants?

Yes. We frequently partner with economic damages consultants, valuation experts, and forensic accountants to supply the empirical marketing foundation for financial calculations.

Our support focuses on two primary areas: (1) Impression-to-Revenue Conversion Modeling: bridging raw search impressions or click logs into lost revenue or unjust enrichment figures; and (2) Full-Funnel DTC Cost Validation: auditing end-to-end ("soup-to-nuts") unit economics, CAC, media scaling friction, hosting, and fulfillment expenses for Direct-to-Consumer business models (as demonstrated in Tolkowsky v. Signet Jewelers).

When should trial counsel retain a digital marketing & paid search expert witness?

It is optimal to retain an expert prior to issuing Rule 34 discovery requests. Digital ad logs (Google Ads, Bing Ads, Meta Ads) and server-side analytics (GA4, ad servers) are often subject to short retention cycles. Retaining an expert early ensures you request the exact ad auction logs, negative keyword lists, and attribution parameters required to build a rock-solid case.

How do you withstand Daubert challenges regarding digital marketing methodology?

Methodological rigor is grounded in standard industry frameworks (such as Google's official ad auction mechanics, peer-reviewed attribution models, and accepted statistical sampling methods) rather than subjective opinion. When opposing counsel mounted a formal Daubert challenge in federal district court against our marketing and search engine methodology, the court overruled the challenge and the testimony was permitted.

What evidence is required for a forensic paid search keyword or GA4 attribution audit?

Typically, we request raw CSV exports or direct read-only access to Google Ads campaign history, search terms reports, impression share reports, organic search console data, and GA4 property event logs. If direct platform access is unavailable, structured discovery productions of change logs and billing records can be audited.

What is your engagement structure for consulting vs. testifying expert roles?

We offer both testifying expert witness engagements (Rule 26 reports, depositions, trial testimony) and non-testifying consulting expert arrangements (protected under attorney work-product privilege for early evaluation or cross-examination strategy). Fee schedules are provided promptly upon conflict clearance.

What happens after I get in touch?

Amanda Schlumpf personally reads every message and responds within 24 business hours. Before discussing any substance, she runs a conflict check on the parties. Once conflicts clear, we schedule a short scoping call and provide the fee schedule and full CV so you can move to engagement quickly.
