This examiner grants 94% of resolved cases

Analysis

Examiner Cox maintains an exceptionally high allowance rate of 94.4% in Art Unit 2813. With 843 resolved cases, this data point indicates that almost all applications reaching a final disposition are granted. The median days to allowance of 649 is also remarkably low, suggesting a very fast and efficient prosecution cycle within Tech Center 2800. This combination of a 94.4% success rate and a 649-day timeline makes this examiner among the most favorable for applicants.

The interview lift of 3.0% is small, likely because the baseline allowance rate of 94.4% leaves little room for improvement. In the 843 resolved cases, interviews were likely used only for the most complex issues. Practitioners can expect a high probability of success and a quick resolution without necessarily needing to rely on frequent interviews. The 649-day median pendency is a key advantage for applicants seeking rapid patent protection. Given the 843 resolved cases, these metrics are highly reliable and suggest that a standard, well-prepared application will likely move through prosecution with minimal resistance and high efficiency.
