Analysis

BROWN, MICHAEL J handles cases in art unit 2115 within tech center 3600, with 1061 resolved cases in the profile. The allowance rate is 87.9%, the interview lift is 8.8%, and the median time to allowance is 960 days. The combination presents a high allowance outcome with a comparatively limited measured interview effect within this profile, so written prosecution strategy and initial claim framing warrant particular attention.

The represented companies include Emerson Electric Co., General Electric Company, and FANUC Corporation. The leading firms are BUCKLEY, MASCHOFF & TALWALKAR LLC, FERGUSON CASE ORR PATERSON LLP, and Kilpatrick Townsend & Stockton LLP - East Coast. Counsel can use this participant history to identify relevant portfolio experience, while the median timeline supports planning around prosecution duration rather than assuming that a favorable allowance rate eliminates delay.
