Tech Center 2800 • Art Units: 2852 2853
This examiner grants 96% of resolved cases
Examiner Sophia S. Chen maintains a prolific record in Tech Center 2800 and Art Unit 2852, with 1574 resolved cases. The data shows an exceptionally high allowance rate of 95.7%. This 95.7% rate indicates that nearly all applications assigned to this examiner result in a grant. Furthermore, the median days to allowance is 531, which suggests a very rapid prosecution timeline. This 531-day period is significantly shorter than the timelines seen in other art units.
The interview lift for this examiner is 4.5%. Given the 95.7% baseline allowance rate, the 4.5% lift provides a small additional benefit for applicants. Direct communication may help in finalizing the few cases that do not immediately reach allowance. In Art Unit 2852, the 531-day median pendency is a key advantage for practitioners. The 1574 resolved cases provide a very high level of statistical certainty for these performance metrics.
Applicants working with this examiner in Tech Center 2800 can expect an efficient process. The 95.7% allowance rate and the 4.5% interview lift suggest that applications are likely to be granted with minimal friction. The 531-day median to allowance is a notable benchmark for speed in the patent office. With 1574 cases of experience, the examiner's profile is one of the most favorable for patent applicants.
