Analysis

Charles S Laughlin serves in Tech Center 3600 and Art Unit 2117, where he has completed 396 resolved cases. His allowance rate of 76.5% is favorable, and the median days to allowance is 1100. This data indicates a consistent prosecution environment for patent applications. The 1100-day median suggests an extended window for reaching a final disposition in these 396 resolved cases. Practitioners can use this 1100-day figure to set expectations for the total duration of the examination process.

The interview lift of 9.6% is low relative to the 76.5% allowance rate, suggesting that written prosecution is often sufficient to reach an allowance. While the 76.5% rate is high, the 1100-day median pendency suggests that applicants should still prepare for a multi-stage process. With 396 resolved cases, the examiner demonstrates a steady approach where the 9.6% lift provides a small advantage. Practitioners may find that the 76.5% allowance rate is achievable through clear written arguments, though the 9.6% lift remains an option for complex issues. This profile suggests that the 1100-day timeline is a primary factor to manage during prosecution.
