Inputs & assumptions
For every numeric input, provide a base value and a 1σ uncertainty. The calculator runs a Monte Carlo simulation to estimate value dispersion.
Report details

How the estimator works
Estimate of value. The headline figure is the Monte Carlo mean of patent net present value (NPV) produced by the Los & Stigter Patent Evaluator.
Standard deviation. Dispersion of simulated NPVs after sampling uncertain inputs from truncated normal distributions.
Profit uplift method. Incremental EBIT can include price premium, variable-cost savings, market-share uplift, and fixed-cost savings.
Royalty method. Royalty benefit is modeled from revenue base, market royalty rate, patent apportionment, coverage, erosion, tax, risk, and discounting.
Risk factors. Commercialization probability and patent validity/enforceability probability are applied as expectation multipliers to annual cash flows.

Actual outcomes may differ materially due to patent scope, validity, enforceability, jurisdiction, field-of-use limits, competitive design-arounds,
