Analysis

LEWIS, TISHA D is assigned to Tech Center 3600 and Art Unit 3611. The profile records 1247 resolved cases, an 87.7% allowance rate, and a median of 811 days to allowance. Interviews show a 9.6% lift, a positive association that is smaller than the profile's allowance measure. Practitioners may therefore emphasize clear initial claim drafting and use interviews selectively.

Representative companies include Robert Bosch GmbH, Volvo Group, and ZF Friedrichshafen AG. The leading firms are NORTON ROSE FULBRIGHT US LLP, BUCHANAN, INGERSOLL & ROONEY PC, and CARRIER SHENDE AND ASSOCIATES PC. The substantial record and relatively short median timing support early, focused prosecution planning.
