Analysis

KRETZER, CASEY L is assigned to tech center 2600 and art unit 2634. The record includes 733 resolved cases, an allowance rate of 86.8%, an interview lift of 12.8%, and a median of 741 days to allowance. Cases associated with interviews had a higher allowance outcome than the overall record.

(TC), FOLEY & LARDNER LLP, and ARENTFOX SCHIFF LLP. The substantial resolved-case record supports using the profile for prosecution planning. The high allowance rate and median timing provide a historical basis for expecting a comparatively direct resolution in suitable cases, while the positive interview lift supports selective examiner engagement. Practitioners should still document claim interpretation and prior-art distinctions in the written response.
