What This Means

With a 35.5% 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, 35.9% of applications that filed an appeal were subsequently allowed. This appeal filing benefit rate is above the USPTO average, suggesting that filing an appeal can be an effective strategy for prompting 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 is strategically valuable. The act of filing often prompts favorable reconsideration during the mandatory appeal conference.

Art Unit 2658 - Prosecution Statistics Summary

Executive Summary

Art Unit 2658 is part of Group 2650 in Technology Center 2600. This art unit has examined 7,593 patent applications in our dataset, with an overall allowance rate of 81.7%. Applications typically reach final disposition in approximately 27 months.

Comparative Analysis

Art Unit 2658's allowance rate of 81.7% places it in the 66% 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 2658 receive an average of 1.99 office actions before reaching final disposition (in the 65% percentile). The median prosecution time is 27 months (in the 63% 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 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.
