Six signals, one estimate
Empirical IP valuation studies consistently find that forward citationforward citationA later patent that cites this one as prior art. High counts signal foundational influence.Read more → count is the single strongest predictor of patent value — heavily cited patents are roughly 10–20× more valuable than the median. Time-to-expiry sets the upper bound on remaining enforceability. ClaimsclaimsThe numbered statements at the end of a patent that legally define what the inventor owns.Read more → count and prior-art depth shape defensibility. LitigationlitigationA lawsuit over patent infringement. Litigated patents often signal commercial importance.Read more → history is a strong commercial-relevance signal. Industry sets the baseline because biotech and pharma patents typically command higher premiums than mechanical or consumer-product patents.
