This examiner grants 60% of resolved cases

Analysis

Robert James Kallal has managed 100 resolved cases within Tech Center 2800 and Art Unit 1671. His allowance rate of 60.0 percent indicates a balanced prosecution environment where a majority of applications eventually reach grant. However, the median days to allowance of 1531 suggests that the path to a patent is relatively long, often spanning the 1531-day median.

The interview lift of 32.4 percent is a standout figure, suggesting that interviews are particularly impactful for this examiner. This lift provides a strong incentive for practitioners to schedule interviews to navigate the 100 cases effectively. While the 60.0 percent allowance rate is solid, the 1531-day median duration implies that persistence is necessary. Utilizing the 32.4 percent interview lift may be the most efficient way to address rejections and potentially shorten the prosecution cycle in Art Unit 1671.
