Allowance Rates

Overall Allowance Rate

Likelihood of Allowance Based on Examiner's Full USPTO Tenure
About this graph

The allowance rate is calculated using the total number of applications issued and abandoned as follows:

Each examiner's metrics are calculated from all applications assigned to them across their lifetime tenure at the USPTO. In the future I plan to implement a filter which provides fine-grained control over this setting, allowing users to specify custom timeframes to look at.

Allowance Rate Before First Final Rejection

Likelihood of Early Allowance
About this graph

The allowance rate is calculated using the total number of applications issued and abandoned as follows:

Each examiner's metrics are calculated from all applications assigned to them across their lifetime tenure at the USPTO. In the future I plan to implement a filter which provides fine-grained control over this setting, allowing users to specify custom timeframes to look at.

Allowance Rate After First Final Rejection

Likelihood of Allowance After RCE's, etc.
About this graph

The allowance rate is calculated using the total number of applications issued and abandoned as follows:

Comparative Allowance Rates

About this graph

Compare the examiner's allowance rate with the overall allowance rate of the examiner's art unit and the overall allowance rate of the USPTO. If the examiner is known to be a current USPTO employee, the art unit used in the comparison is the examiner's current art unit. If the examiner cannot be identified as a current USPTO employee, the art unit of the examiner's last filed application is used.

All allowance rates are calculated using the total number of applications issued and abandoned as follows:

Each examiner's metrics are calculated from all applications assigned to them across their tenure. Art unit and USPTO metrics are calculated from all applications filed in the past 15 years. In the future I plan to implement filters which provide fine-grained control over these settings, allowing users to specify custom timeframes to look at.
