Analysis

Shelley Chen is an examiner in Technology Center 3600 and Art Unit 3661. The examiner has managed 542 resolved cases. The allowance rate is 66.2 percent, providing a statistical baseline for the likelihood of obtaining a patent grant. This figure suggests that the majority of applications are successful after meeting the examiner's requirements.

The interview lift is 20.4 percent. This positive metric indicates that conducting an interview increases the probability of allowance. For practitioners, this suggests that engaging in a dialogue is a productive way to advance prosecution and potentially resolve rejections more effectively than through written responses alone. The 20.4 percent lift is a significant factor in strategic planning.

The median days to allowance is 1237. This number indicates the typical length of the prosecution process for allowed cases. With a 66.2 percent allowance rate, the process is likely to result in a grant, but the 1237 day median suggests that it will require a significant time investment. These data points help practitioners plan their strategy and manage the timeline for their patent applications.
