Analysis

Ruben C Parco Jr, in Art Unit 2853 of Tech Center 2800, has resolved 468 cases with an allowance rate of 46.2 percent. The median days to allowance is 1224. An interview lift of 16.1 percent suggests that interviews are a helpful strategy for moving cases toward allowance and overcoming the moderate success rate.

Robert Bosch GmbH, Rohm Co., Ltd., and Safran S.A. are top companies in this docket. These companies are represented by firms like NORTON ROSE FULBRIGHT US LLP, Rabin & Berdo, P.C., and Blueshift IP LLC. These practitioners must manage the 1224 median days to allowance during the prosecution cycle.

The 46.2 percent allowance rate indicates that fewer than half of the resolved cases reach issuance. The 16.1 percent interview lift provides a path for practitioners to improve these odds through direct engagement. The 1224 median days to allowance serves as a benchmark for the expected duration of successful applications with this examiner.
