Appeals Overview

This analysis examines appeal outcomes and the strategic value of filing appeals for art-unit 1799.

What This Means

With a 39.0% reversal rate, the PTAB reverses the examiner's rejections in a meaningful percentage of cases. This reversal rate is in the top 25% across the USPTO, indicating that appeals are more successful here than in most other areas.

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, 27.3% of applications that filed an appeal were subsequently allowed. This appeal filing benefit rate is in the bottom 25% across the USPTO, indicating that filing appeals is less effective here than in most other areas.

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 1799 - Prosecution Statistics Summary

Executive Summary

Art Unit 1799 is part of Group 1790 in Technology Center 1700. This art unit has examined 7,130 patent applications in our dataset, with an overall allowance rate of 65.6%. Applications typically reach final disposition in approximately 35 months.

Comparative Analysis

Art Unit 1799's allowance rate of 65.6% places it in the 22% percentile among all USPTO art units. This art unit has a significantly lower allowance rate than most art units at the USPTO.

Prosecution Patterns

Applications in Art Unit 1799 receive an average of 2.30 office actions before reaching final disposition (in the 78% 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 challenging 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.
