Analysis

Grant Carson Currens is an examiner in Tech Center 1700 and Art Unit 1600. He has 152 resolved cases and an allowance rate of 54.6 percent. This moderate rate suggests a balanced examination process. However, the standout figure is the interview lift of 62.5 percent. This is an extraordinary value, suggesting that interviews are highly successful in moving a case toward an allowance.

The median time to allowance is 1156 days, which is a standard duration for 152 resolved cases. This timeline indicates a typical prosecution cycle in Tech Center 1700. The 62.5 percent lift is a critical data point, as it suggests that the path to a grant is significantly smoothed by direct verbal communication with the examiner. Without an interview, the odds of success appear much lower.

For practitioners, the 62.5 percent lift is a mandate to request an interview at the earliest opportunity. While the 54.6 percent allowance rate is decent, the lift is the primary driver of success in the 152 resolved cases. The 1156-day median pendency means that applicants should be prepared for a multi-year process, but the high effectiveness of interviews provides a clear strategy for success in Art Unit 1600.
