Listed by the USPTO as COBY, FRANTZ

Tech Center 2400 • Art Units: 2156 2164 2415 2454 2456 2459

This examiner grants 91% of resolved cases

Analysis

Frantz Coby maintains a high-volume docket in Tech Center 2400 and Art Unit 2156, with 756 resolved cases. The allowance rate of 90.6% suggests a favorable environment where most applications reaching a final resolution result in a grant. This efficiency is further evidenced by a median days to allowance of 879, which indicates a relatively swift prosecution cycle for companies like MediaTek Inc. and ZTE Corporation.

Unlike many other examiners, the interview lift for this profile is a modest 5.1%. This suggests that while interviews are not detrimental, they do not provide a dramatic increase in success compared to the 90.6% baseline, likely because the initial allowance probability is already high. Firms such as Alliance IP, LLC and Brooks Kushman P.C. may find that well-drafted initial applications are often sufficient to secure a patent without extensive verbal negotiation.

LG Electronics Inc. is another major applicant frequently appearing in these 756 resolved cases. The 879-day median pendency provides a reliable timeline for intellectual property strategy. For practitioners at Arch & Lake LLP, the data indicates that the primary challenge is not overcoming a low allowance probability but rather managing the standard 5.1% lift through efficient communication when necessary.
