Analysis

Alexander Usyatinsky serves in Tech Center 1700 and Art Unit 1726, having completed 907 resolved cases. His allowance rate is 83.1%, which is a strong indicator of a high probability of success for applicants. This 83.1% rate suggests that the examiner is generally receptive to the arguments and amendments presented during prosecution. The 907 cases provide a robust dataset for understanding the prosecution landscape in this art unit.

The data also reveals an interview lift of 19.0%, which is a significant increase in the likelihood of allowance. This suggests that interviews are a highly effective strategy for resolving issues with this examiner. Furthermore, the median days to allowance is 1024, providing a clear expectation for the duration of the prosecution process. The 19.0% lift is a compelling reason for practitioners to engage in direct dialogue to potentially shorten the 1024-day median wait.

Practitioners should view the 19.0% interview lift as a key tool for navigating Art Unit 1726. While the 83.1% allowance rate is already favorable, the impact of an interview can be very beneficial for more complex cases. With 907 cases resolved, these metrics offer a reliable guide for strategic decision-making. The 1024-day median pendency should be factored into the overall timeline, with the understanding that active engagement can lead to more efficient outcomes.
