Analysis

Caleb Logan Esquino examines applications in Art Unit 2677 of Tech Center 3600. He has 31 resolved cases with an allowance rate of 58.1 percent. This rate suggests a moderate level of difficulty for applicants. The interview lift is 6.0 percent, which is a positive but modest indicator.

The median days to allowance for his cases is 1076. Top companies such as Samsung Electronics Co., Ltd., Robert Bosch GmbH, and Huawei Technologies Co., Ltd. are frequently found in his docket. Law firms like BANNER & WITCOFF, LTD., SUGHRUE MION, PLLC, and Dinsmore & Shohl LLP - Qualcomm are among the top representatives. The 1076 median days to allowance provides a benchmark for the duration of successful cases. Although the 31 resolved cases represent a smaller sample, the 58.1 percent allowance rate and 6.0 percent interview lift offer useful strategic guidance. Practitioners should view the 1076-day timeline as a standard expectation for Art Unit 2677.
