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, 37.2% 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 2859 - Prosecution Statistics Summary

Executive Summary

Art Unit 2859 is part of Group 2850 in Technology Center 2800. This art unit has examined 22,704 patent applications in our dataset, with an overall allowance rate of 78.3%. Applications typically reach final disposition in approximately 27 months.

Comparative Analysis

Art Unit 2859's allowance rate of 78.3% places it in the 52% percentile among all USPTO art units. This art unit has an above-average allowance rate compared to other art units.

Prosecution Patterns
