Appeals Overview

This analysis examines appeal outcomes and the strategic value of filing appeals for art-unit 3671.

What This Means

With a 32.3% 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, 29.5% 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 3671 - Prosecution Statistics Summary

Executive Summary

Art Unit 3671 is part of Group 3670 in Technology Center 3600. This art unit has examined 23,387 patent applications in our dataset, with an overall allowance rate of 77.0%. Applications typically reach final disposition in approximately 24 months.

Comparative Analysis

Art Unit 3671's allowance rate of 77.0% places it in the 47% percentile among all USPTO art units. This art unit has a below-average allowance rate compared to other art units.

Prosecution Patterns

Applications in Art Unit 3671 receive an average of 1.53 office actions before reaching final disposition (in the 25% percentile). The median prosecution time is 24 months (in the 81% 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 fewer office actions than average, plan for relatively streamlined prosecution.
  • The median prosecution time is shorter 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.
