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, 50.0% 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.

Examiner WAN, DEMING - Prosecution Strategy Guide

Executive Summary

Examiner WAN, DEMING works in Art Unit 3762 and has examined 28 patent applications in our dataset. With an allowance rate of 85.7%, this examiner has an above-average tendency to allow applications. Applications typically reach final disposition in approximately 31 months.

Allowance Patterns

Examiner WAN, DEMING's allowance rate of 85.7% places them in the 63% percentile among all USPTO examiners. This examiner has an above-average tendency to allow applications.

Office Action Patterns

On average, applications examined by WAN, DEMING receive 2.71 office actions before reaching final disposition. This places the examiner in the 80% percentile for office actions issued. This examiner issues more office actions than most examiners, which may indicate thorough examination or difficulty in reaching agreement with applicants.

Prosecution Timeline

The median time to disposition (half-life) for applications examined by WAN, DEMING is 31 months. This places the examiner in the 58% percentile for prosecution speed. Prosecution timelines are slightly faster than average with this examiner.

Interview Effectiveness

Conducting an examiner interview provides a +18.8% benefit to allowance rate for applications examined by WAN, DEMING. This interview benefit is in the 61% percentile among all examiners. Recommendation: Interviews provide an above-average benefit with this examiner and are worth considering.

Request for Continued Examination (RCE) Effectiveness

When applicants file an RCE with this examiner, 14.3% of applications are subsequently allowed. This success rate is in the 10% percentile among all examiners. Strategic Insight: RCEs show lower effectiveness with this examiner compared to others. Consider whether a continuation application might be more strategic, especially if you need to add new matter or significantly broaden claims.

After-Final Amendment Practice

This examiner enters after-final amendments leading to allowance in 33.3% of cases where such amendments are filed. This entry rate is in the 50% percentile among all examiners. Strategic Recommendation: This examiner shows below-average receptiveness to after-final amendments. You may need to file an RCE or appeal rather than relying on after-final amendment entry.

Appeal Withdrawal and Reconsideration

This examiner withdraws rejections or reopens prosecution in 50.0% of appeals filed. This is in the 21% percentile among all examiners. Strategic Insight: This examiner rarely withdraws rejections during the appeal process compared to other examiners. If you file an appeal, be prepared to fully prosecute it to a PTAB decision. Per MPEP § 1207, the examiner will prepare an Examiner's Answer maintaining the rejections.

Petition Practice

When applicants file petitions regarding this examiner's actions, 66.7% are granted (fully or in part). This grant rate is in the 74% percentile among all examiners. Strategic Note: Petitions show above-average success regarding this examiner's actions. Petitionable matters include restriction requirements (MPEP § 1002.02(c)(2)) and various procedural issues.

Examiner Cooperation and Flexibility

Examiner's Amendments: This examiner makes examiner's amendments in 0.0% of allowed cases (in the 45% percentile). This examiner makes examiner's amendments less often than average. You may need to make most claim amendments yourself.

Quayle Actions: This examiner issues Ex Parte Quayle actions in 0.0% of allowed cases (in the 48% percentile). This examiner issues Quayle actions less often than average. Allowances may come directly without a separate action for formal matters.

Prosecution Strategy Recommendations

Based on the statistical analysis of this examiner's prosecution patterns, here are tailored strategic recommendations:

  • Expect multiple rounds of prosecution: This examiner issues more office actions than average. Address potential issues proactively in your initial response and consider requesting an interview early in prosecution.

Relevant MPEP Sections for Prosecution Strategy

  • MPEP § 713.10: Examiner interviews - available before Notice of Allowance or transfer to PTAB
  • MPEP § 714.12: After-final amendments - may be entered "under justifiable circumstances"
