Analysis

Madhuri R. Herzog examines applications in Tech Center 2400 and Art Unit 2431. With 681 resolved cases, the examiner maintains an allowance rate of 78.3%. This high rate indicates a very favorable environment for applicants, where many cases result in a grant. The median days to allowance is 1073, providing a clear expectation for the duration of the prosecution cycle.

The interview lift is 12.4%. While this 12.4% lift is positive, it is relatively modest, suggesting that the examiner is already highly inclined toward allowance. The 78.3% allowance rate is the dominant factor for this docket. Practitioners should still consider interviews to resolve specific issues, but the 1073-day median pendency is likely to be the standard timeline regardless of verbal engagement.

In Art Unit 2431, the 681 resolved cases offer a reliable dataset. The 78.3% allowance rate and 1073-day timeline are the primary metrics for strategy. The 12.4% interview lift provides an additional benefit. Attorneys can approach this examiner with a high expectation of success, using these 681 cases as a guide for their prosecution strategy.
