Analysis

Ronak C. Patel is an examiner in Tech Center 3700 and Art Unit 1611. With 674 resolved cases, the examiner has a significant track record. The allowance rate is 51.2 percent, which indicates a moderate path to patentability where about half of the cases result in a grant.

The interview lift is 56.4 percent, which is exceptionally high. This 56.4 percent lift indicates that interviews are a powerful tool for overcoming rejections and moving cases toward allowance. When compared to the 51.2 percent base allowance rate, the impact of an interview is very strong, making it a critical strategic choice for practitioners.

The median days to allowance is 1291. This timeline represents the typical duration for successful applications to reach a grant. Given the 56.4 percent interview lift, practitioners should prioritize early interviews to potentially shorten the 1291 day pendency and improve the 51.2 percent chance of allowance in Art Unit 1611.
