Analysis

Examiner Je Hwan John Park is assigned to Tech Center 3700 and Art Unit 3761. The profile currently reflects 3 resolved cases, all of which resulted in a 0.0 percent allowance rate. This outcome is the same as the interview lift, which is also 0.0 percent. The median days to allowance is recorded at 1305.

The 0.0 percent allowance rate indicates that the 3 resolved cases in this record have not reached a grant. Because the interview lift matches the baseline, the data does not yet show a statistical benefit to direct communication for these specific matters. The 1305 median days to allowance provides a benchmark for the time investment required in this art unit.

The companies involved in these resolved cases include CJ CheilJedang Corporation, LG Electronics Inc., and Toyota Motor Corporation. Firms such as Bryan Cave Leighton Paisner LLP (DC), Chrisman Gallo Tochtrop LLC, and Dority & Manning, P.A. and Haier US Appliance have navigated this examiner's requirements. These representatives must account for the current metrics when developing their prosecution strategies.
