Patent valuation uses several recognised methods, depending on the patent’s industry, commercial potential, and available data. The three main approaches are cost-based, income-based, and market-based, along with more advanced option-based models.
Cost Approach
The cost approach estimates the value of a patent by calculating the expenses required to create, develop, or replace the invention. It includes research and development, testing, regulatory approvals, and legal fees.
This method is useful when:
Historical cost data is available
The patent is new and yet to generate revenue
Comparable market data is limited
Typical evaluation elements include development cost, reproduction cost, and replacement cost.
Income Approach (Discounted Cash Flow / Royalty Method)
The income approach values a patent based on the financial benefits it is expected to generate over its remaining useful life. It forecasts revenue or royalty income attributable directly to the patent and discounts it to present value.
Two applications are common:
This approach is widely used in industries where patents generate ongoing revenue streams.
Market / Comparable Approach
The market approach evaluates a patent based on prices of similar patent transactions. It compares recent sales, licences, or transfers involving comparable technologies.
This method is commonly used when:
There is an active market for similar patents
Sufficient transaction data is available
Comparable technologies share similar characteristics
It provides a realistic valuation based on market-driven pricing.
Option / Real Options Approach
The real options approach treats patents as strategic options that provide future choices under uncertainty. It values the patent based on potential opportunities such as expansion, licensing, or abandonment.
This method is suitable when:
Future outcomes are uncertain
The patent enables multiple commercial pathways
Market volatility affects revenue projections
It is commonly used for early-stage technologies, pharmaceuticals, and research-driven industries.
