Listed by the USPTO as MA, WEI

Tech Center 2100 • Art Units: 2135

This examiner grants 73% of resolved cases

Analysis

Wei Ma has resolved 111 cases in Art Unit 2135, maintaining an allowance rate of 73.0 percent. The median days to allowance of 1032 suggests a prosecution timeline of nearly three years. Semiconductor and technology leaders like Micron Technology Inc. and SK hynix Inc. are frequent applicants in Tech Center 2100. For Apple Inc., the 73.0 percent allowance rate and 1032-day median pendency offer a predictable and successful prosecution path.

The interview lift of 6.3 percent is relatively modest, indicating that the examiner's 73.0 percent baseline allowance rate is the primary driver of success. For firms like AMPACC Law Group, PLLC and Dickinson Wright RLLP, while interviews provide a small benefit, well-structured written arguments may be equally effective. IP & T Group LLP can use the 6.3 percent lift for final claim adjustments. With 111 resolved cases, the data suggests that the 1032-day timeline is a consistent metric, and the high baseline success rate is the most prominent feature of this examiner's profile.
