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, 45.8% 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 face challenges. Ensure your case has strong merit before committing to full Board review.

✓ Filing a Notice of Appeal is strategically valuable. The act of filing often prompts favorable reconsideration during the mandatory appeal conference.

Art Unit 2656 - Prosecution Statistics Summary

Executive Summary

Art Unit 2656 is part of Group 2650 in Technology Center 2600. This art unit has examined 12,264 patent applications in our dataset, with an overall allowance rate of 84.4%. Applications typically reach final disposition in approximately 23 months.

Comparative Analysis

Art Unit 2656's allowance rate of 84.4% places it in the 79% percentile among all USPTO art units. This art unit has a significantly higher allowance rate than most art units at the USPTO.
