Patent Valuation — Patent Value Assessment
Enhances the IP valuation capabilities of the ip-analyst and license-strategist agents.
Valuation Methodologies
Three Approaches
| Approach |
Method |
Best Suited For |
| Cost Approach |
Cost of development/acquisition |
Early-stage, no alternative technology |
| Market Approach |
Comparable IP transaction data |
Comparable transactions exist |
| Income Approach |
Present value of future income |
Clear monetization pathway |
Cost Approach
Reproduction Cost:
= R&D Labor + Materials + Equipment + Overhead
+ Opportunity Cost (time value)
- Depreciation (functional/economic obsolescence)
Example:
R&D Cost: $500,000
Overhead: $100,000
Obsolescence Depreciation: -20%
Value: (500,000 + 100,000) x 0.8 = $480,000
Market Approach
Comparable Transaction Comparison:
Value = Comparable IP Transaction Price x Adjustment Factor
Adjustment Factors:
- Technology similarity (0.5-1.5)
- Market size ratio
- Remaining protection period ratio
- Rights scope (exclusive/non-exclusive)
Income Approach (Relief from Royalty)
Value = Sum of [Revenue_t x Royalty Rate x (1-Tax Rate) / (1+r)^t]
t: Remaining patent term (1 to N years)
r: Discount rate (WACC basis, 12-20%)
Royalty Rate: Industry-specific benchmark (see below)

25% Rule (Rule of Thumb)
Royalty = Licensee Operating Profit x 25%
Rationale: 25% of patent-contributed profit goes to the patent holder
Caveat: Courts use this only as a reference, not an absolute standard

License Structure Design
License Types
| Type |
Description |
Royalty Structure |
| Exclusive |
Only licensee may practice |
High upfront + royalty |
| Non-exclusive |
Multiple licensees |
Lower upfront + royalty |
| Sublicensable |
Relicensing permitted |
Royalty sharing agreement |
| Cross-license |
Mutual practice rights |
Royalty-free or balancing |
Royalty Structures
Lump-sum: One-time payment at agreement
Running Royalty: Periodic payment based on sales/volume
Minimum Royalty: Annual minimum guarantee
Milestone: Stage-based payments (development/commercialization)
Hybrid: Lump-sum + running combination
