Tech Center 1600 • Art Units: 1632 1645

This examiner grants 10% of resolved cases

Analysis

Peter Paras Jr. examines applications in Tech Center 1600 and Art Unit 1632, with 60 resolved cases. His allowance rate of 10.0% is exceptionally low, indicating a very challenging environment for securing a patent grant. This 10.0% rate suggests that the vast majority of applications do not result in an allowance. The 60 resolved cases provide a focused look at the rigorous standards applied in this art unit.

The median days to allowance is 1608, which represents a very long prosecution period. This 1608-day figure indicates that even successful applications face a multi-year journey to grant. For applicants, the 1608 days to allowance is a critical factor for long-term strategic planning and budgeting. This 1608-day duration is a primary characteristic of the prosecution experience in Tech Center 1600 under his review.

The interview lift of 7.8% offers a small but potentially important advantage. This 7.8% lift suggests that interviews can slightly improve the very low 10.0% base allowance rate. While the 7.8% lift may not guarantee success, it remains one of the few tools available to practitioners for advancing an application. Given the 60 resolved cases, the 7.8% lift should be considered as part of a comprehensive strategy in Art Unit 1632.
