Analysis

Christopher J. Kohlman serves in Tech Center 3700 and Art Unit 2617, where he has processed 620 resolved cases. He maintains an allowance rate of 81.8%, which is paired with a median days to allowance of 729. This 729-day metric suggests a specific prosecution path for major applicants such as LG Display Co., Ltd., Google LLC, and Qualcomm Incorporated. The 81.8% allowance rate provides a baseline for the probability of success in Art Unit 2617.

The interview lift for this examiner is 2.1%. This 2.1% lift indicates that the 81.8% allowance rate is largely independent of whether an interview is conducted. Firms like BRAKE HUGHES BELLERMANN LLP, FISH & RICHARDSON P.C. (TC), and HONGKONG IP may find that written advocacy is a primary factor given the existing grant frequency. With 620 resolved cases, the data indicates that applications move toward resolution according to the 729-day median. The 2.1% lift is a modest factor in his overall prosecution profile.
