IPQ® Score
The IPQ score objectively rates patent assets based on a proven statistical methodology. The IPQ score is mathematically determined from the identified metrics for each patent using our patented and proprietary rating system.
The IPQ score has a median of 100. Patent assets with higher IPQ scores are statistically more likely to generate economic returns. As a person's credit score is used by banks and lenders to determine financial risk, a patent asset's IPQ score is used by IP professionals, investors, and corporate strategic planners to determine value and quality.
IPQ scores are unique to each particular patent examined and are updated monthly. Scores are based on certain identified predictive variables determined to have statistically significant correlation to patent quality and value.
Typical metrics include:
- Number, length and type of patent claims,
- A mount and type of prior art cited,
- Number of forward citations or references made by later-issued patents,
- Presence or absence of limiting claim language,
- Patent prosecution history
- 50 other relevant internal and external factors
Market Validation of the Value of IPQ Scores
An independent blind study conducted in partnership with a major Fortune-100 company determined that IPQ scores were statistically correlated to the probability of rated patents producing economic benefit (a licensed or commercialized patent) or no economic benefit (non-licensed, non-commercialized).
The obvious implication of the study is that IPQ scores can be effective at helping companies identify and leverage economically significant patents or technologies while avoiding or culling those that are less promising.
Class Percentile Rank
Patents are ranked on a percentile-basis according to IPQ score. The percentile rank represents the proportion of patents in a given population that have IPQ scores less than or equal to the reported score. For instance, if a patent receives an IPQ score of 125 and this is greater than or equal to 90% of other patents in a given population, the patents' percentile rank would be 90% relative to that population.
The search tool and reports rank patents according to five different populations or groupings:
- Overall - all patents
- "Field" - same field
- "Class" - same class
- "Subclass" - same class/subclass
- "Assignee" - same assignee
Rating
Letter grades are assigned to each patent based on percentile rankings of IPQ scores among issued patents.
- Patent Rank (percentile) Rating
- Bottom 5% C-
- Between 40th and 60th B
- Top 5% A+
