Analysis

NEGIN, RUSSELL SCOTT has resolved 912 cases in Tech Center 2100 and Art Unit 1631. The allowance rate is 55.9%, and the median time to allowance is 1515 days. The large record supports treating the outcome as a meaningful prosecution signal. It also shows a difficult path to allowance with lengthy pendency, so applicants should plan claim strategy and commercial timing well before filing.

The interview lift is 34.2%, a strong positive association that makes a carefully prepared interview a significant consideration. Tempus Al Inc., BENEVOLENTAI BIO LIMITED, and Samsung Electronics Co., Ltd. are the leading listed companies. FOLEY & LARDNER LLP, SMITH BALUCH LLP, and THE WEBB LAW FIRM, P.C. are the principal listed firms. Interviews may help focus issues, but the allowance risk remains material.
