Analysis

Kareen Kay Thomas serves in Tech Center 3700 and Art Unit 1653, with a large volume of 1350 resolved cases. Her allowance rate is 77.0, and the median days to allowance is 806. These statistics indicate a productive and relatively efficient path to patent issuance for a high number of applications. The 1350 resolved cases provide a very robust data set for evaluating examiner tendencies.

The interview lift of 17.1 is a positive factor for practitioners. This lift suggests that direct communication can significantly enhance the 77.0 allowance rate. With 1350 resolved cases, the 806 day timeline is a reliable benchmark, and the 17.1 interview lift provides a clear mechanism for resolving rejections and securing a grant. Applicants in Art Unit 1653 should consider the interview as a standard part of their prosecution strategy. The combination of a 77.0 allowance rate and an 806 day median pendency makes this a favorable environment for applicants who utilize the 17.1 interview lift to address examiner concerns in Tech Center 3700.
