Analysis

Alan S. Chen, an examiner in Tech Center 4100, has a high volume of 1152 resolved cases with an allowance rate of 91.0%. This exceptionally high rate in Art Unit 2100 suggests a very favorable environment for patent grants. The median time to allowance is 1005 days, which provides a clear expectation for the duration of the prosecution process. Practitioners can rely on the 1005-day figure when planning their timelines for the 1152 resolved cases.

The interview lift of 6.7% indicates a small but positive impact on the 91.0% allowance rate. This suggests that while the examiner is already highly likely to allow a case, an interview can still provide a slight advantage. The 1152 resolved cases in Tech Center 4100 offer a robust dataset for evaluating these trends. The 6.7% lift is a useful tool for resolving specific issues that may arise during the 1005-day median pendency.

In Art Unit 2100, the 91.0% allowance rate and the 1005-day median time to allowance point toward an efficient and successful prosecution path. The 1152 resolved cases reflect a consistent and predictable approach by Examiner Chen. Applicants should factor the 6.7% interview lift into their strategy to ensure the best possible outcome within the 1005-day window.
