Patent Examiner Statistics: PatentAdvisor ETA™

LexisNexis PatentAdvisor®は、特許審査官の行動を予測するための、最も有益な評価基準です。
ETA™ は、特許を取得できる可能性と難易度を予測します

Now you can easily, and with more accuracy than ever, predict your assigned examiner’s behavior. With variability at every level of the USPTO, use ETA to visually see how efficient or inefficient your assigned examiner works and tailor your prosecution strategy accordingly.

ETA’s inventors discuss why this metric is revolutionary:





ETA is a PatentAdvisor™ exclusive metric that is based on a proprietary algorithm that measures how an examiner behaves. It is a predictive indicator of prosecution length that can easily identify cases that require extra care and a carefully crafted prosecution strategyKnow when to build your strongest approach and when to appeal. 

With ETA, LexisNexis IP helps our customers better understand their length of prosecution or anticipated number of office actions. All so you can expedite your success.

Effectively predict your assigned examiner’s behavior.

Instantly Identify Your Favorability with Color Coding


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.
