Discovery is the most powerful tool to dissect and discredit damages claims. From interrogatories to expert depositions, litigators can use discovery to challenge speculative calculations and demand transparency in financial assertions.

In commercial litigation—including intellectual property, contract, and business tort disputes—damages calculations are frequently inflated, vague, or based on unsupported assumptions. The discovery process offers litigators a crucial opportunity to probe the foundation of those claims, compel the production of underlying financial data, and uncover inconsistencies in opposing expert reports.

📉 Without effective discovery, a party may face exaggerated demands based on skewed projections or manipulated profit models.
✅ But by using targeted requests for documents, interrogatories, and expert disclosures, savvy litigators can dismantle inflated damages narratives and reframe the monetary scope of a case.

🎯 Why This Guide Matters

Mastering discovery techniques to challenge damages claims helps you:
• ✅ Identify flaws and assumptions in opposing expert models
• ✅ Demand production of key financials to expose overstatements
• ✅ Equip your own expert with data to build a credible countermodel
• ✅ Strengthen motion practice and settlement leverage

1. Dissecting the Damages Theories Early

💼 Most damages models fall into one or more of the following categories:
• Lost profits
• Reasonable royalty (in IP)
• Expectation or reliance damages (in contract cases)
• Restitution or unjust enrichment

Early in the case, use Rule 26 disclosures and interrogatories to require the opposing party to identify:
• The specific damages theory being used
• The assumptions behind that theory
• The experts (if any) supporting it

🛠 Discovery Strategy: File targeted interrogatories asking for a breakdown of the components of the damages model—revenues, costs, timeframes, and causal links to alleged wrongdoing.

2. Document Requests That Strike at the Core

To effectively challenge an opposing party’s damages claims, you must go beyond surface-level figures and dig into the financial machinery behind their assertions. Carefully tailored requests for production (RFPs) can uncover inconsistencies, unsupported assumptions, and outright exaggerations.

These requests should be designed to do more than just gather documents—they should undermine the foundation of the damages model itself by exposing key weaknesses in causation, reliability, or methodology.

📄 Key Document Categories & Their Strategic Value:

🔍 Internal Financial Projections (Pre/Post-Incident)

Request internal forecasts, business plans, and profit/loss statements from before and after the alleged wrongful act. These documents can reveal:

• Whether the party was already underperforming

• If the “but-for” world they present in their damages model is unrealistic

• Inconsistencies between litigation claims and actual business expectations

💬 Example: If a plaintiff claims lost profits due to breach but had projected declining revenues months earlier, this undercuts their entire damages narrative.

💰 Sales and Cost Data for Affected Products/Services

This is the raw material of most damages calculations. Request:

• Monthly or quarterly sales volumes and pricing

• Cost of goods sold (COGS)

• Margin reports

• SKU-level or product-line breakdowns

Why? Because opposing experts often cherry-pick favorable timeframes or average margins that overstate losses. Detailed data allows your expert to reconstruct more accurate financial models.

💡 Practice Tip: Demand production in native spreadsheet format (e.g., Excel) with unlocked cells—so you can trace formulas and spot “handcrafted” edits.

🧾 Communications on Profitability, Pricing, or Customer Impact

These records can provide real-world insights that contradict or confirm the party’s damages assertions. Look for:

• Internal emails or memos about price adjustments

• Discussions about demand fluctuations

• Sales team reports on customer churn or retention

🎯 Strategic Goal: Find indications that losses were due to market shifts, competition, or internal mismanagement—not the alleged conduct.

📑 Comparable License Agreements or Royalty Benchmarks (IP Cases)

In intellectual property disputes, damages often rely on hypothetical royalty rates. Request:

• Past license agreements involving the asserted IP

• Third-party licenses for similar technology

• Communications related to licensing negotiations

⚠️ Why It Matters: If the plaintiff’s model is based on a “reasonable royalty,” but they historically licensed similar IP for far less, their damages theory may collapse under scrutiny.

🧠 Investment Memos, Budgets, and Board Presentations

High-level strategic documents often tell a more honest story about the business’s actual valuation of projects, products, and risks.

Request:

• Annual budgets and variance analyses

• Board slide decks discussing financial outlook

• Internal valuations of key business units or IP assets

📊 These can reveal that a project or product was deprioritized, forecasted to underperform, or even abandoned—contradicting inflated damages narratives.

3. Pinpointing Overreach with Interrogatories

Use Rule 33 interrogatories to extract specific claims and assumptions that may be vague or misleading in initial disclosures.

📋 Sample Interrogatory Angles:
• Identify all factual bases for claimed lost profits
• Detail every customer allegedly lost and the reason
• Explain any alternative causation factors considered (or ignored)
• List all third-party financial data used in models

⚠️ Be alert for conclusory answers and prepare to follow up with a motion to compel if responses are incomplete or evasive.

4. Requests for Admission: Lock Down Weak Points

Strategically crafted requests for admission (RFAs) help narrow disputes and expose gaps.

✅ Sample Admissions to Consider:
• Admit that no actual customer communications confirm lost business
• Admit that no contemporaneous documents estimate losses
• Admit that revenues increased during the relevant period
• Admit that no comparable licenses support the claimed royalty

🎯 Use these admissions to undercut the credibility of opposing claims—and to support motions for summary judgment.

5. Expert Discovery: Turning the Tables

Expert testimony often forms the backbone of damages claims. Use Rule 26(a)(2) reports, expert depositions, and document subpoenas to challenge their conclusions.

💼 Key Expert Challenges:
• Question unsupported assumptions (e.g., market share loss, price erosion)
• Demand models reflect real-world data—not hypotheticals
• Probe for industry inexperience or bias in retained experts
• Use rebuttal experts with forensic accounting skills to build an alternate narrative

💡 Practice Tip: Request all communications and drafts shared with the expert—unless limited by protective orders.

6. Common Pitfalls—and How to Avoid Them

🚫 Don’t let damages discovery become a missed opportunity. Avoid these mistakes:

❌ Waiting too long to serve tailored requests
❌ Failing to tie document demands to specific damages claims
❌ Overlooking discovery from third parties (e.g., lost customers)
❌ Neglecting to involve your own damages expert early

✔️ Proactive Planning: Coordinate your discovery strategy with your financial experts from day one.

7. Motion Practice: When to Strike

If the opposing side refuses to disclose supporting evidence or provides vague justifications, be ready to file:

📄 Motion to Compel: Show how requested data is essential to test their damages theory
📄 Motion to Exclude: Challenge experts under Daubert for unreliable methodologies
📄 Motion for Summary Judgment: Argue damages are speculative or unsupported

💡 Strategic Insight: Courts scrutinize damages claims heavily—particularly in IP and business tort cases. Demonstrating due diligence in discovery enhances your credibility and chances of a favorable ruling.

Case Examples: Damages Discovery in Action

🔍 Case 1 – Exposing Lost Profits Gaps
A defendant used interrogatories and internal sales data to show that the plaintiff’s claimed lost profits never materialized in real time. The court granted partial summary judgment limiting damages.

🔍 Case 2 – Royalty Rate Unraveled
Requests for licensing history showed that the plaintiff’s “reasonable royalty” demand far exceeded industry norms. The expert’s report was excluded under Daubert.

🔍 Case 3 – Admission Strategy Success
Admissions confirmed the plaintiff never tracked lost customer data. This gutted their claimed damages and led to a favorable settlement.

Practical Tips for Damages Discovery

• 🎯 Tie discovery directly to claimed models (e.g., lost profits, royalties)
• 📋 Push for full disclosure of financial projections, forecasts, and historical data
• 🤝 Involve financial experts to refine and target discovery requests
• 🔍 Use RFAs to challenge unsubstantiated assumptions
• 🧠 Leverage motions to compel and exclude when stonewalled

FAQs

Q1: What if damages are based on assumptions I can’t verify?
Use discovery to demand all underlying documents, and depose the expert on each assumption.

Q2: Can I ask for native Excel files?
Yes—this allows you to audit formulas and spot inconsistencies.

Q3: What if their damages expert uses a method I believe is flawed?
Challenge the expert with a Daubert motion and use a rebuttal expert to expose flaws.

Q4: How soon should I begin targeting damages in discovery?
Immediately after disclosures—early targeting prevents delays and missed opportunities.

Q5: Can I depose company finance staff directly?
Yes—corporate representatives under Rule 30(b)(6) are often deposed on damages topics.

Final Thoughts

Challenging damages through discovery isn’t just about poking holes—it’s about reframing the narrative. With precise requests and strategic follow-up, you can neutralize inflated demands, influence case valuation, and shift the settlement posture in your favor.
