This examiner grants 91% of resolved cases

Analysis

Herve-Louis Y. Assouman examines cases in Art Unit 2642 of Tech Center 4100, where he has a high volume of 682 resolved cases. His allowance rate of 91.3% is remarkably high, suggesting a very favorable environment for patent applicants. Furthermore, the median days to allowance is 775, indicating a relatively swift path to grant compared to many other units at the USPTO.

The interview lift for this examiner is 4.1%. While this is a positive figure, its impact is limited by the fact that the 91.3% allowance rate is already near the ceiling. For the 682 resolved cases, an interview provides a small additional benefit, but the baseline probability of success is already very high. Practitioners can expect an efficient prosecution experience in Tech Center 4100, with the 775-day median timeline and the 91.3% allowance rate reflecting a streamlined path to securing patent rights.
