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, 37.1% of applications that filed an appeal were subsequently allowed. This appeal filing benefit rate is in the top 25% across the USPTO, indicating that filing appeals is particularly effective here. The act of filing often prompts favorable reconsideration during the mandatory appeal conference.

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 2842 - Prosecution Statistics Summary

Executive Summary

Art Unit 2842 is part of Group 2840 in Technology Center 2800. This art unit has examined 27,285 patent applications in our dataset, with an overall allowance rate of 90.2%. Applications typically reach final disposition in approximately 19 months.

Comparative Analysis

Art Unit 2842's allowance rate of 90.2% places it in the 90% percentile among all USPTO art units. This art unit has a significantly higher allowance rate than most art units at the USPTO.

Prosecution Patterns

Applications in Art Unit 2842 receive an average of 1.23 office actions before reaching final disposition (in the 8% percentile). The median prosecution time is 19 months (in the 96% 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 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.
