Methodology

Our grant rate is based on a timeline of dispositions of applications. This shows you how likely you are to get a patent and also when you are likely to get it. The example timeline here is for the entire USPTO, and we also have timelines for each examiner.

To compare exmainers, we use the 3-year grant rate (3YGR), which is the percentage of applications granted by 3-years after the first office action.

Our current dataset is all utility patent applications filed in 2010 or later. This gives us plenty of data for computing 3-year grant rates but also allows us to focus on more recent data in case an examiner's behavoir changes over time.

For large enough data sets, the percentage of grants and abandonments will be always increasing over time. For some examiners, however, you'll see that the number of grants and abandonments can decrease over time. That is because the size of the data set is shrinking.

Grant Rate Timeline

Below is the grant rate timeline for USPTO, where the timeline is relative to the date of the first office action. The three-year grant rate is the percentage of applications granted at three years after the first office action.
