Antitrust Internal Investigation Summary
Produces a privilege-protective, board-ready memo synthesizing internal antitrust investigation findings for technology platform companies under US federal law.
Quick Start
Before drafting, collect:
- Investigation charter — directing authority, investigators, dates, privilege posture
- Factual record — triggering complaint, implicated contracts, internal comms, product decision docs, regulator correspondence
- Interview materials — Upjohn-warned summaries (role, topics, key assertions)
- Market context — products, monetization, rivals, switching costs, network effects, prior assessments
- Remediation status — stop-gap steps, policy updates, product/contract changes
- Procedural posture — anticipated litigation, M&A, preservation holds
If critical inputs are missing, request them: "To provide a competent risk assessment, I require [specific items]."
Output Structure
The memo contains seven sections in order.
1. Privilege Header
Every page:
ATTORNEY–CLIENT PRIVILEGED / ATTORNEY WORK PRODUCT
Prepared at the direction of counsel to provide legal advice regarding
antitrust compliance and potential exposure. Intended solely for [Company]
senior leadership and the Board of Directors. Do not forward outside
those who need to know for purposes of receiving legal advice.
2. Executive Summary
BLUF format. Frame each finding as: Issue → Key Facts → Legal Significance → Risk Level → Recommended Action
Anchor three risk pillars:
- Legal Liability — strength of potential claims
- Regulatory Scrutiny — DOJ/FTC enforcement probability
- Reputational Impact — downstream effects on partners, developers, public
3. Investigation Scope & Methodology
Cover: triggering event, time period, products/units, conduct categories, document sources, custodian/interview counts, analyses performed, known gaps. Be specific without creating a discovery roadmap.
4. Key Findings
Organize by issue, not witness or chronology. Map each finding to:
| Theory | Statute | Key Elements |
|---|
| Monopolization | Sherman Act § 2 | Monopoly power + willful acquisition/maintenance [VERIFY citations] |
