This examiner grants 30% of resolved cases

Analysis

Vy Bui Rossi serves in Art Unit 1671 of Tech Center 3700. The examiner has managed 44 resolved cases, resulting in an allowance rate of 29.5 percent. This low allowance rate suggests a very rigorous examination process for applications in this art unit, where the majority of cases do not result in a grant. The 44 resolved cases provide an initial but clear indication of the examiner's high standards and the significant hurdles applicants must overcome.

The interview lift is 36.4 percent, indicating that interviews are a highly effective strategy for applicants. Despite the low overall allowance rate, direct communication appears to significantly improve the probability of a grant, as shown by the 36.4 percent lift. This suggests that the examiner is open to being persuaded by strong verbal arguments and technical clarifications. Practitioners should view the interview as an indispensable part of their strategy when working with this examiner to increase their chances of success.

The median days to allowance is 1608. This is a very long duration, reflecting a protracted prosecution process that requires significant persistence. The 1608-day median is a critical data point for applicants to use when forecasting the timing and cost of their patent efforts. It highlights the need for a long-term perspective and the allocation of sufficient resources to sustain a prosecution that may last several years before reaching a final decision.
