What This Means

With a 43.5% 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, 36.4% 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 3653 - Prosecution Statistics Summary

Executive Summary

Art Unit 3653 is part of Group 3650 in Technology Center 3600. This art unit has examined 15,360 patent applications in our dataset, with an overall allowance rate of 80.0%. Applications typically reach final disposition in approximately 25 months.

Comparative Analysis

Art Unit 3653's allowance rate of 80.0% places it in the 63% percentile among all USPTO art units. This art unit has an above-average allowance rate compared to other art units.
