Instantly Identify Your Favorability with Color Coding

We have further broken down the ETA data point into easy-to-understand color categories that identify, in the most simplistic terms, whether you have been assigned a favorable or less favorable examiner.

Red = ETA of 6+, indicating a high likelihood of long prosecution length. The examiner may have less experience, grant less than 15 applications per year on average, or have a high backlog of pending cases.

Yellow = ETA of 2.6-5.9, indicating mediocre prosecution length. The examiner has average experience and grants between 15-150 applications per year, on average.

Green = ETA of .1-2.5, indicating high likelihood of a short prosecution length. The examiner has lots of experience and grants over 150 applications per year, on average.
