This examiner grants 76% of resolved cases

Analysis

Angela M. Lie works in Art Unit 2163 within Tech Center 3900. The examiner has 212 resolved cases with an allowance rate of 76.4 percent. This high rate suggests a generally favorable outlook for applicants. The interview lift is 6.9 percent, which shows a modest increase in the probability of allowance following an interview. This indicates that while interviews are helpful, the examiner is already inclined toward allowance in many cases.

The median days to allowance is 1363, representing a lengthy period from filing to grant. Practitioners should be prepared for this 1363 day duration even with the high 76.4 percent allowance rate. The 212 resolved cases provide a stable basis for these metrics, suggesting that the examiner's tendencies are consistent across a large volume of work in Tech Center 3900.

In Art Unit 2163, the 76.4 percent allowance rate is a positive sign for practitioners. Although the 6.9 percent interview lift is not as dramatic as in other units, it still offers a tactical advantage. The primary challenge for applicants is the 1363 day median wait time, which should be managed through clear communication and efficient responses to office actions.
