What This Means

With a 36.6% 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, 32.6% 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 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 shows limited benefit. Consider other strategies like interviews or amendments before appealing.

Art Unit 3753 - Prosecution Statistics Summary

Executive Summary

Art Unit 3753 is part of Group 3750 in Technology Center 3700. This art unit has examined 40,194 patent applications in our dataset, with an overall allowance rate of 78.5%. Applications typically reach final disposition in approximately 26 months.

Comparative Analysis

Art Unit 3753's allowance rate of 78.5% places it in the 53% percentile among all USPTO art units. This art unit has an above-average allowance rate compared to other art units.

Prosecution Patterns
