Appeals Overview

This analysis examines appeal outcomes and the strategic value of filing appeals for art-unit 1776.

What This Means

With a 30.3% reversal rate, the PTAB reverses the examiner's rejections in a meaningful percentage of cases. This reversal rate is below the USPTO average, indicating that appeals face more challenges here than typical.

Understanding Appeal Filing Strategy

Filing a Notice of Appeal can sometimes lead to allowance even before the appeal is fully briefed or decided by the PTAB. This occurs when the examiner or their supervisor reconsiders the rejection during the mandatory appeal conference (MPEP § 1207.01) after the appeal is filed.

In this dataset, 31.8% of applications that filed an appeal were subsequently allowed. This appeal filing benefit rate is below the USPTO average, suggesting that filing an appeal has limited effectiveness in prompting favorable reconsideration.

Strategic Recommendations

⚠ Appeals to PTAB face challenges. Ensure your case has strong merit before committing to full Board review.

⚠ Filing a Notice of Appeal shows limited benefit. Consider other strategies like interviews or amendments before appealing.

Art Unit 1776 - Prosecution Statistics Summary

Executive Summary

Art Unit 1776 is part of Group 1770 in Technology Center 1700. This art unit has examined 16,052 patent applications in our dataset, with an overall allowance rate of 77.7%. Applications typically reach final disposition in approximately 29 months.

Comparative Analysis

Art Unit 1776's allowance rate of 77.7% places it in the 51% percentile among all USPTO art units. This art unit has an above-average allowance rate compared to other art units.
