Judicial Apportionment Models for Trade Secret Damages in PRC Intermediate IP Courts
PRC Intermediate IP Courts limit trade secret damages to net profits directly driven by proprietary secrets, deducting market, capital, and non-infringing inputs.
Market Contribution Factor
Meaning
Quantitative parameters established during intellectual property litigation measure the percentage of commercial value directly created by an infringed technical solution. The market contribution factor determines how much of a defendant’s total sales revenue or gross profit stems from the unauthorized use of a patent, utility model or trade secret. Courts in China apply this coefficient within damages assessments governed by Supreme People’s Court guidelines on patent and trade secret infringement.
Calculating this value requires distinguishing technical drivers from commercial factors such as marketing expenditure, established brand reputation and existing supply chain efficiencies.
Valuation Metric
Economic evaluators calculate this parameter by comparing the market price of the complete product with the costs of alternative non-infringing technical solutions.
Judicial Application
Judges adjust the numerical multiplier based on expert appraisal reports and industry profit benchmarks. High coefficients apply when the patented technology constitutes the core functional mechanism of the product, driving consumer purchasing decisions. Conversely, lower values are assigned when the protected invention represents a minor assembly component or an incremental operational improvement.
In complex manufacturing cases involving consumer electronics or industrial machinery, courts routinely assign a market contribution factor ranging between ten percent and thirty percent to reflect the multi-faceted nature of product value.
Proof Assessment
Evidentiary submissions dictate whether courts accept a proposed percentage or substitute discretionary statutory estimates. Litigants submit consumer surveys, historical pricing data, research and development cost comparisons and licensing agreements for similar technologies to substantiate their proposed coefficient. Where a defendant refuses to produce audited account books or manufacturing cost structures, judicial interpretations permit judges to adopt the plaintiff’s proposed market contribution factor in full as a sanction for evidentiary obstruction.
