Analysis

Rehana Perveen is a patent examiner in Art Unit 2100 within Tech Center 2100. She has 42 resolved cases in her profile, providing an initial look at her prosecution tendencies. The allowance rate of 83.3% is quite high, suggesting that applicants have a strong probability of success. This metric indicates a favorable environment for those seeking to obtain patent grants in this specific art unit, even with a relatively small sample size.

The interview lift for this examiner is 0.0%. This figure indicates that interviews have not yet demonstrated a statistical impact on the probability of allowance in the cases resolved so far. This may be due to the high baseline allowance rate, where many cases are granted through written prosecution alone. Practitioners should focus on high-quality written submissions, as the data suggests that the examiner is highly receptive to the merits of the applications as filed. An interview may still be useful for clarification, but it is not a statistical driver of success.

The median days to allowance is 1338, which provides a benchmark for the expected duration of the prosecution cycle. This timeframe is relatively long, which should be factored into the overall strategy for applications in Tech Center 2100. By combining the 83.3% allowance rate with the 1338 day median pendency, applicants can develop a realistic approach to navigating the examination process. The data suggests that while the process may take time, the likelihood of a positive outcome is high.
