Appeals Overview

This analysis examines appeal outcomes and the strategic value of filing appeals for art-unit 2161.

What This Means

With a 34.8% reversal rate, the PTAB reverses the examiner's rejections in a meaningful percentage of cases. This reversal rate is above the USPTO average, indicating that appeals have better success 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, 30.1% 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 show good success rates. If you have a strong case on the merits, consider fully prosecuting the appeal to a Board decision.

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

Art Unit 2161 - Prosecution Statistics Summary

Executive Summary

Art Unit 2161 is part of Group 2160 in Technology Center 2100. This art unit has examined 9,769 patent applications in our dataset, with an overall allowance rate of 76.6%. Applications typically reach final disposition in approximately 35 months.

Comparative Analysis

Art Unit 2161's allowance rate of 76.6% 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.

Prosecution Patterns

Applications in Art Unit 2161 receive an average of 2.39 office actions before reaching final disposition (in the 83% percentile). The median prosecution time is 35 months (in the 30% percentile).

Strategic Considerations

When prosecuting applications in this art unit, consider the following:

  • The art unit's allowance rate suggests a more favorable examination environment compared to the USPTO average.
  • With more office actions than average, plan for multiple rounds of prosecution.
  • The median prosecution time is longer than average and should be factored into your continuation and client communication strategies.
  • Review individual examiner statistics within this art unit to identify examiners with particularly favorable or challenging prosecution patterns.
