Analysis

Sevan A. Aydin is an examiner in Tech Center 2800 and Art Unit 2852. He has managed 572 resolved cases with an allowance rate pct of 80.1%. This 80.1% rate indicates that a majority of the applications in his portfolio result in a grant. The median days to allowance for these cases is 661, which establishes a timeline for practitioners to expect when prosecuting in this art unit. For the 572 resolved cases, this 661-day period represents the median duration from filing to issuance for successful applications.

The data shows an interview lift pct of 4.5%. This 4.5% lift is an increase in the probability of allowance when an interview is conducted compared to the 80.1% baseline allowance rate. This suggests that while the baseline rate is high, direct communication with the examiner still provides a benefit. Practitioners can use the 4.5% lift to evaluate the impact of an interview, as it correlates with a higher success rate than the baseline. The 661-day median suggests that the process in Art Unit 2852 is relatively efficient for the 572 resolved cases.
