Analysis

Darcey E. Gottschalk maintains a highly efficient docket in Tech Center 2900, with an allowance rate of 89.6 percent across 936 resolved cases. The median days to allowance is notably short at 648, indicating a rapid path to grant in Art Unit 2919. This efficiency benefits applicants like Haleon UK Ip Limited and Jiabao Wang, who can expect a resolution in less than two years. The 89.6 percent allowance rate suggests a very high probability of success for those filing in this unit.

The interview lift of 3.6 percent is modest, suggesting that while interviews are slightly beneficial, the high 89.6 percent allowance rate is largely driven by the examiner's standard review process. With a 648-day median pendency, applicants can expect quick resolutions without the need for extensive oral advocacy. The data reflects a very favorable environment for securing patent rights with minimal friction, where the baseline allowance rate is already so high that interviews offer only a marginal statistical advantage.
