Analysis

PIZIALI, ANDREW T is assigned to technology center 1700 and art unit 1786. The record contains 763 resolved cases, with an allowance rate of 28.4%. The substantial volume makes the low allowance rate a meaningful feature of the profile rather than an isolated observation.

The median time to allowance is 1637 days. Interview lift is 27.4%, indicating a positive relationship between interviews and allowance, but the overall outcome pattern remains difficult.

The recurring companies are Certainteed LLC, Reifenhäuser GmbH & Co. Kg Maschinenfabrik, and Bmic LLC. The listed firms are Abel Schillinger, LLP, BURR & FORMAN - MAGNERA CORPORATION, and HSML P.C. Practitioners should anticipate prolonged prosecution, develop strong amendment positions, and use interviews deliberately to address barriers to allowance.
