Analysis

Lydia E. Edwards manages a docket in Art Unit 1657 within Tech Center 2800, where she has 709 resolved cases. Her allowance rate is 60.1%, and the median days to allowance is 1279. This pendency figure suggests a longer prosecution cycle for granted patents compared to examiners with shorter timelines.

The interview lift for this examiner is 6.0%, indicating a modest improvement in the 60.1% allowance rate when an interview is conducted. Major applicants include Merck Patent GmbH, Global Life Sciences Solutions USA LLC, and Sansure Biotech Inc. Legal representation is often provided by MILLEN, WHITE, ZELANO & BRANIGAN, P.C., BOTOS CHURCHILL IP LAW LLP, and Clements Bernard Walker.

With 709 resolved cases, the 1279-day median pendency provides a stable expectation for applicants. While the 6.0% interview lift is positive, the majority of allowances are likely achieved through written prosecution. Practitioners should plan for a thorough examination process given the current 60.1% allowance rate and the time required to reach a final resolution.
