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, 47.1% 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 NIU, FENG - Prosecution Strategy Guide

Executive Summary

Examiner NIU, FENG works in Art Unit 2669 and has examined 360 patent applications in our dataset. With an allowance rate of 76.4%, this examiner has a below-average tendency to allow applications. Applications typically reach final disposition in approximately 25 months.

Allowance Patterns

Examiner NIU, FENG's allowance rate of 76.4% places them in the 42% percentile among all USPTO examiners. This examiner has a below-average tendency to allow applications.

Office Action Patterns

On average, applications examined by NIU, FENG receive 1.84 office actions before reaching final disposition. This places the examiner in the 42% percentile for office actions issued. This examiner issues fewer office actions than average, which may indicate efficient prosecution or a more lenient examination style.

Prosecution Timeline

The median time to disposition (half-life) for applications examined by NIU, FENG is 25 months. This places the examiner in the 79% percentile for prosecution speed. Applications move through prosecution relatively quickly with this examiner.

Interview Effectiveness

Conducting an examiner interview provides a +6.9% benefit to allowance rate for applications examined by NIU, FENG. This interview benefit is in the 35% percentile among all examiners. Recommendation: Interviews provide a below-average benefit with this examiner.

Request for Continued Examination (RCE) Effectiveness

When applicants file an RCE with this examiner, 20.1% of applications are subsequently allowed. This success rate is in the 22% 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 49% 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.

Pre-Appeal Conference Effectiveness

When applicants request a pre-appeal conference (PAC) with this examiner, 28.6% result in withdrawal of the rejection or reopening of prosecution. This success rate is in the 31% percentile among all examiners. Note: Pre-appeal conferences show below-average success with this examiner. Consider whether your arguments are strong enough to warrant a PAC request.

Appeal Withdrawal and Reconsideration

This examiner withdraws rejections or reopens prosecution in 64.3% of appeals filed. This is in the 44% percentile among all examiners. Of these withdrawals, 66.7% occur early in the appeal process (after Notice of Appeal but before Appeal Brief). Strategic Insight: This examiner shows below-average willingness to reconsider rejections during appeals. Be prepared to fully prosecute appeals if filed.

Petition Practice

When applicants file petitions regarding this examiner's actions, 54.5% are granted (fully or in part). This grant rate is in the 56% 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 0.3% of allowed cases (in the 55% percentile). This examiner makes examiner's amendments more often than average to place applications in condition for allowance (MPEP § 1302.04).

Quayle Actions: This examiner issues Ex Parte Quayle actions in 0.7% of allowed cases (in the 58% percentile). This examiner issues Quayle actions more often than average when claims are allowable but formal matters remain (MPEP § 714.14).

Prosecution Strategy Recommendations

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

    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"
    • MPEP § 1002.02(c): Petitionable matters to Technology Center Director
    • MPEP § 1004: Actions requiring primary examiner signature (allowances, final rejections, examiner's answers)
    • MPEP § 1207.01: Appeal conferences - mandatory for all appeals
    • MPEP § 1214.07: Reopening prosecution after appeal
