Analysis

SHEN, SAMUEL has 127 resolved cases in Tech Center 2100 and Art Unit 2141. The allowance rate is 43.3%, and the median time to allowance is 1170 days. The interview lift is 21.1%, suggesting that interviews may improve outcomes even though the overall allowance rate remains below the profile’s other prosecution measures.

Astute IP Law Group, Cooper Legal Group LLC, and EDELL, SHAPIRO & FINNAN, LLC appear among the leading firms. The 127-case record is narrower than profiles with higher case volumes, so practitioners should treat the rate and interview signal as useful directional evidence rather than a complete picture of practice in Art Unit 2141.
