This examiner grants 0% of resolved cases

Analysis

Ethan Alexander Tuttle operates within Tech Center 2800 and Art Unit 2800. The examiner has resolved 1 case, which resulted in an allowance rate of 0.0%. This single resolution also shows an interview lift of 0.0%. The median days to allowance for this examiner is recorded at 1073. With only 1 resolved case, these figures represent a very limited data set for predictive analysis. Practitioners should view the 0.0% allowance rate and 1073-day median as preliminary data points rather than established trends.

The 0.0% interview lift indicates that the single resolved case did not benefit from an interview, or an interview was not conducted. Given the 1073-day median, applicants should be prepared for a significant duration even with a small sample size. Strategy in Art Unit 2800 should remain flexible as more cases are resolved by this examiner. The 1 resolved case provides a starting point for understanding the examiner's process, but the 0.0% allowance rate may not be indicative of future outcomes. Practitioners should monitor this profile for additional data to refine their approach. The 1073-day timeline is the only current benchmark for pendency.
