What Is My Patent Worth? Three Valuation Frameworks
"What's my patent worth?" Depends on who's asking and what decision the number will drive. A reference guide.
The Three Frameworks
Cost: totals what was spent creating the asset. Easy to document, useful as a floor. Cost has no necessary relationship to value.
Market: what comparable patents sold or licensed for. Strong where genuine comparables exist; most prices are confidential, so it corroborates rather than concludes.
Income: present value of the cash flow the patent drives. Most defensible for commercialized technology.
Three inputs carry it:
The revenue share genuinely attributable to the patented feature.
A discount rate reflecting real risk, including validity and eligibility exposure and whether infringement can be detected and proven.
Remaining life measured by commercial relevance, not legal term.
Matching the Method to the Moment
Fundraising: investors price risk reduction, not patents. Clean chain of title and claims that map to revenue move term sheets.
M&A: know the fair market floor. A strategic premium appears when the patent blocks a specific buyer's roadmap. That premium is negotiation leverage.
Licensing: apply the royalty to the smallest saleable unit that practices the patent, not total product revenue.
What Prosecution History Does to the Number
The file wrapper is valuation evidence. Arguments made to overcome rejections become public record and can narrow how claims are construed. Amendments made to secure allowance can surrender coverage of equivalents. Two patents with identical claim language can carry different values because one was argued into allowance and the other was drafted into it.
The discipline: lean amendments adding only the minimum limitation, arguments that distinguish art without shrinking the invention, a file history an acquirer can read without finding surrendered scope. A short, clean prosecution isn't just cheaper. It appraises better.
The Durable Factors
Detectability: infringement observable from outside supports value. Server-side processes that can't be observed carry a structural discount.
Specification depth: claims can only be amended to what was disclosed at filing. Thin specs cap options and value.
Chain of title: one unassigned inventor can make a strong patent unsellable, independent of claim quality.
Portfolio mapping: asset-by-asset linkage to products and competitors is what diligence rewards.
Companies whose patents appraise well can explain what each patent covers, who it stops, and what it protects. The explanation is the value. The number reports it.
