Analysis

Kashif Siddiqui is a high-volume examiner in Tech Center 2600 and Art Unit 2415. With 1292 resolved cases, the examiner maintains an allowance rate of 88.0 percent. This 88.0 percent allowance rate suggests a favorable environment for patent applicants. The data from these 1292 resolved cases indicates that the vast majority of applications in this unit proceed to grant.

The interview lift is 8.6 percent. Given that the allowance rate is already 88.0 percent, the impact of interviews is more limited but still provides a measurable benefit. Practitioners should consider the 8.6 percent lift as a secondary strategy if initial written responses do not lead to an allowance. This figure is derived from the large pool of 1292 cases resolved by the examiner.

The median days to allowance is 804. This 804-day median reflects a consistent and relatively efficient pace of examination. Practitioners can use this duration to set expectations for the length of the prosecution cycle in Art Unit 2415. The 804-day benchmark is a reliable metric for planning strategy in Tech Center 2600.
