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, 33.4% 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 3633 - Prosecution Statistics Summary

Executive Summary

Art Unit 3633 is part of Group 3630 in Technology Center 3600. This art unit has examined 16,155 patent applications in our dataset, with an overall allowance rate of 66.4%. Applications typically reach final disposition in approximately 24 months.

Comparative Analysis

Art Unit 3633's allowance rate of 66.4% places it in the 23% 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 3633 receive an average of 1.86 office actions before reaching final disposition (in the 46% percentile). The median prosecution time is 24 months (in the 85% 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.
