Valuation by Absence: Modeling Evidentiary Gaps in Patent Value Assessment

Examines how missing technical, deployment and economic evidence should influence the confidence and posture of a patent valuation. The framework treats evidentiary absence explicitly, allowing an assessment to proceed, narrow its range, flag high uncertainty or abstain where the available record is insufficient.

Overview


Patent valuation commonly relies on affirmative evidence such as technical mappings, product implementation, licensing history, citations and market information. This paper examines the complementary problem: what should happen when material evidence is absent? It formalises evidentiary absence as an explicit analytical input rather than leaving missing information to implicit expert judgment. The framework evaluates evidence across three principal layers—technical, deployment and economic—and assigns evidence states ranging from absent and semantic proximity to structured and corroborated evidence. The resulting evidentiary profile defines how far a valuation can responsibly proceed. Missing technical mapping can limit confidence in technical contribution; deployment opacity can restrict market-use inference; and economic silence can constrain the defensibility of royalty or damages assumptions. Importantly, the framework does not convert missing evidence into an automatic numerical discount or infer that the patent has no value. Instead, it supports different valuation postures: proceed, constrain the range, identify high uncertainty or abstain. This makes evidentiary sufficiency itself visible within the valuation process.


Key Findings

  1. Evidence is assessed across technical, deployment and economic layers rather than collapsed into a single availability test.

  2. The framework uses four evidence states: absent, semantic proximity, structured evidence and corroborated evidence.

  3. Missing evidence does not imply zero value or non-use; it limits the conclusions that can defensibly be drawn from the available record.

  4. Abstention is treated as a legitimate valuation outcome when evidence is too incomplete to support a defensible estimate.
