Clarivate (ClarivateThe evaluation method for the Global Top 100 Innovative Institutions adopts the Derwent Innovation Index (Derwent Strength Index), retrieves data from Derwent World Patents Index, one of the world's most authoritative patent databases, and quantitatively assesses patent quality across five dimensions. Below are the detailed measurement dimensions and calculation methods:

I. Evaluation Process:

l  Step 1: Filter candidate institutions

From around the globe3,000filter from institutions that meet both of the following criteria:

1. Historical Accumulation Threshold: From2000The total number of publicly disclosed inventions since the year exceeds500Item

2. Recent activity threshold: based on2025For example, in a five-year evaluation period (such as2020-2024within {0} years, obtain more than100Licensed Invention

l  Step 2: Patent Quality Assessment

Score each patent held by candidate institutions using the Derwent Innovation Index.

l  Step 3: Overall Ranking

Based on international patent innovation output over the past five years, the Global Top 100 Innovative Institutions are finalized.

II. Five Measurement Dimensions of the Derwent Impact Index:

Clarivate evaluates each invention using the Derwent Strength Index, which is based on the following five core dimensions:

l  Influence:Measure the frequency and breadth of citations by subsequent patents to evaluate patent quality, reflecting technical leadership. This metric assesses the technology's role in driving industry development.      

l  Investment Intensity: Evaluates the geographic coverage and financial scale of patent applications and maintenance. This metric reflects a company's commitment to technology and its market strategy.      

l  Success Rate: Evaluates patent grant rate, patent family size, and legal status stability. This metric measures the success of commercialization and legal protection for innovation outcomes.      

l  Uniqueness/Scarcity: Assesses the novelty of the technology and its differentiation from existing solutions. This metric evaluates technological breakthroughs and irreplaceability.      

l  Global Coverage: Evaluate patents across multiple countries/Geographic footprint. This metric reflects the technology's global value and business ambition.      

III. Quantitative Evaluation Methods for Patent Quality

l  Rating System

（1)  Relative Scoring: Each invention is scored against a global benchmark rather than in isolation, with relative performance determined by comparing it to patents in the same field worldwide.

（2)  Invention-level scoring: Evaluates individual inventions rather than entire patent families for precision.

（3)  Comprehensive Score Summary: Aggregates scores across all inventions to evaluate the organization's overall innovation strength.

l  Key Metrics

Influence (InfluenceQuantification:

（1)  Citations (number of times cited by subsequent patents)

（2)  Citation Velocity (Time Span of Citations)

（3)  Citation Breadth (Diversity of Sources)

l  Success Rate (SuccessQuantification:

（1)  Patent Grant Rate = Number of Authorized Patents / Number of Patent Applications

（2)  Patent family size (number of patent applications for the same invention filed in different countries)

（3)  Patent Maintenance Duration (Reflects Continuity of Commercial Value)

l  Uniqueness (RarityQuantification:

（1)  Uniqueness of Technical Categories (IPC/CPCCategory scarcity

（2)  Differentiation from prior art

（3)  Novelty of the technology stack

l  Investment Scale and Global Reach:

（1)  Number of countries in patent portfolio

（2)  Cumulative costs for patent application and maintenance

（3)  PCTInternational Patent Application Ratio

4. Calculate Overall Score

l  Step 1: Raw values for each dimension of the individual patent→StandardizeZmin

Clarivate does not use a fixed percentage-based scoring system. Instead, it employs global benchmarking across the entire database with normal distribution standardization, ensuring all metrics are consistently aligned.DWPIGlobal Patent Dataset (6700 ten thousand + Patent) Apply z-score normalization:

Zi​=σXi​−μ​

• Xi​: Raw quantitative value of a single patent in a certain dimension (cited) / same family / Scarcity Frequency)


• μMean of all patents in the same global technical field


• σ: Global standard deviation for this metric in the same technical field

Rules:Z＞0 Above the global averageZ＜0 Below average; automatically truncates extreme outliers (Top 1%、Bottom1%Avoid extreme value interferenceClarivate。

l  Step 2: Single Patent D-WPI Intensity (Four ItemsZValue Aggregation)

1. Aggregation method: Weighted geometric mean, not simple arithmetic sum

DSISingle Patent= Z1 Z2 Z3​​Z4geometric mean*Base Calibration Coefficient

• Key Rule: Any DimensionZfor negative values, overallDSIReduce reliance on single high scores masking patent weaknesses.


• Benchmark Calibration Factor: Annual Full DatabaseDSIDistribution normalization coefficients are dynamically adjusted annually based on the global patent pool to ensure score comparability across years.

Clarivate does not disclose publicly. 4 Fixed weight coefficients across four dimensions; empirical calculation of the weight range for the four dimensions: Influence 32%~35%Regional Investment 28%~30%, Scarcity 22%~25%, patent success rate 12%~15%。

l  Step 3: Calculate from single patent score→Institutional Base Score (Median, Not Mean)

Extract all authorized patents from shortlisted institutions during the evaluation periodDSIThe median score is used to determine the institution's base score.

Use the median instead of the arithmetic mean to avoid skewing by a few high-value patents or dragging down the average with numerous low-quality ones, ensuring an accurate representation of the institution's core patent quality.

l  Step 4: Weighting Internationalization Factors→Final Comprehensive Score of the Institution (Top 100 Ranking Score)

Institution Base Score*The internationalization weight factor is used to calculate the final institutional score.

Internationalization factorsIFCalculation logic: Global average number of institutions per family/Average number of related countries among peer institutions

IF＞1: Global footprint exceeds industry average, leading to a higher overall score;IF＜1Weak overseas footprint; overall rating downgraded.
