# Patent-Specific Discount Rate Calculation
**Patent:** US10958080B2  
**Calculation Date:** November 15, 2025

---

## Executive Summary
The discount rate for this patent valuation has been calculated at **10.835%** by combining the industry risk-free WACC with patent-specific risk premiums. This rate falls within the reasonable range of 10-25% for patent-backed DCF valuations.

---

## 1. Discount Rate Calculation

### Formula
```
Discount Rate = Industry WACC + Patent-Specific Risk Premium
Discount Rate = 4.335% + 6.5% = 10.835%
```

### Components

#### A. Industry WACC (Weighted Average Cost of Capital)
- **Value:** 4.335%
- **Source:** FinancialDataCollector (market-based industry baseline)
- **Description:** Represents the baseline cost of capital for the technology/biotechnology industry, accounting for risk-free rate, equity risk premium, and capital structure.

#### B. Patent-Specific Risk Premium
- **Total Risk Premium:** 6.5%
- **Source:** PatentStrengthAnalyzer
- **Components:**
  - **Patent Maturity Risk:** 3.0%
    - Reflects the development and commercialization stage of the technology
    - Earlier-stage patents carry higher maturity risk
  - **Patent Dependency Risk:** 2.0%
    - Accounts for reliance on other patents or third-party technologies
  - **Litigation/Validity Risk:** 1.5%
    - Captures the probability of invalidity challenges or infringement claims
  - **Technology Maturity Risk:** Already included in base calculation

#### C. Market/Commercialization Risk
- **Status:** Included in patent strength analysis (6.5% total)
- **Rationale:** Patent strength analysis encompasses market risk through maturity, dependency, and litigation components

## 2. Validation and Reasonableness Check

### Discount Rate Range Analysis
| Metric | Value | Status |
|--------|-------|--------|
| Calculated Discount Rate | 10.835% | ✓ Valid |
| Minimum Threshold | 10% | ✓ Above threshold |
| Maximum Threshold | 25% | ✓ Below threshold |
| Recommended Range | 10-25% | ✓ Within range |

**Validation Result:** ✓ PASS - The discount rate of 10.835% is reasonable and falls within industry standard ranges for patent valuations.

### Reasonableness Justification
1. **Comparative Benchmarking:** Patent discount rates typically range from 8-20% for mature, well-protected technologies, and 15-30% for emerging or high-risk patents.
2. **Risk Profile:** The 6.5% patent risk premium reflects:
   - Moderate maturity risk (technology in development/early commercialization)
   - Standard litigation/validity risk
   - Dependency risk indicating some reliance on other patents
3. **Market Conditions:** The 4.335% industry WACC reflects current market conditions with moderate risk-free rates and industry-specific risk premiums.

## 3. Sensitivity Analysis

| Industry WACC | Risk Premium | Discount Rate | Scenario |
|---------------|--------------|---------------|----------|
| 4.335% | 6.5% | 10.835% | **Base Case** |
| 4.335% | 5.5% | 9.835% | Lower Risk |
| 4.335% | 7.5% | 11.835% | Higher Risk |
| 3.335% | 6.5% | 9.835% | Lower WACC |
| 5.335% | 6.5% | 11.835% | Higher WACC |

## 4. Application in DCF Valuation

The calculated discount rate of **10.835%** should be applied as follows:

```
Patent Value = Σ (Cash Flows / (1 + r)^t)
where r = 0.10835 (10.835%)
```

This discount rate will be used in DCF projections to:
- Discount projected cash flows from patent licensing/commercialization
- Estimate present value of future royalty streams
- Calculate terminal value based on perpetual growth assumptions
