Appeals Overview

This analysis examines appeal outcomes and the strategic value of filing appeals for examiner DU, HAIXIA.

What This Means

With a 50.0% 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, 26.7% 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.

Examiner DU, HAIXIA - Prosecution Strategy Guide

Executive Summary

Examiner DU, HAIXIA works in Art Unit 2611 and has examined 422 patent applications in our dataset. With an allowance rate of 86.7%, this examiner has an above-average tendency to allow applications. Applications typically reach final disposition in approximately 26 months.

Allowance Patterns

Examiner DU, HAIXIA's allowance rate of 86.7% places them in the 65% percentile among all USPTO examiners. This examiner has an above-average tendency to allow applications.

Office Action Patterns

On average, applications examined by DU, HAIXIA receive 2.03 office actions before reaching final disposition. This places the examiner in the 52% percentile for office actions issued. This examiner issues a slightly above-average number of office actions.

Prosecution Timeline

The median time to disposition (half-life) for applications examined by DU, HAIXIA is 26 months. This places the examiner in the 76% percentile for prosecution speed. Applications move through prosecution relatively quickly with this examiner.

Interview Effectiveness

Conducting an examiner interview provides a +16.9% benefit to allowance rate for applications examined by DU, HAIXIA. This interview benefit is in the 58% 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, 30.1% of applications are subsequently allowed. This success rate is in the 59% percentile among all examiners. Strategic Insight: RCEs show above-average effectiveness with this examiner. Consider whether your amendments or new arguments are strong enough to warrant an RCE versus filing a continuation.

After-Final Amendment Practice

This examiner enters after-final amendments leading to allowance in 49.4% of cases where such amendments are filed. This entry rate is in the 74% percentile among all examiners. Strategic Recommendation: This examiner shows above-average receptiveness to after-final amendments. If your amendments clearly overcome the rejections and do not raise new issues, consider filing after-final amendments before resorting to an RCE.

Pre-Appeal Conference Effectiveness

When applicants request a pre-appeal conference (PAC) with this examiner, 0.0% result in withdrawal of the rejection or reopening of prosecution. This success rate is in the 9% percentile among all examiners. Note: Pre-appeal conferences show limited success with this examiner compared to others. While still worth considering, be prepared to proceed with a full appeal brief if the PAC does not result in favorable action.

Appeal Withdrawal and Reconsideration

This examiner withdraws rejections or reopens prosecution in 57.9% of appeals filed. This is in the 32% percentile among all examiners. Of these withdrawals, 27.3% 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, 42.4% are granted (fully or in part). This grant rate is in the 34% percentile among all examiners. Strategic Note: Petitions show below-average success regarding this examiner's actions. Ensure you have a strong procedural basis before filing.

Examiner Cooperation and Flexibility

Examiner's Amendments: This examiner makes examiner's amendments in 0.0% of allowed cases (in the 18% percentile). This examiner rarely makes examiner's amendments compared to other examiners. You should expect to make all necessary claim amendments yourself through formal amendment practice.

Quayle Actions: This examiner issues Ex Parte Quayle actions in 0.0% of allowed cases (in the 23% percentile). This examiner rarely issues Quayle actions compared to other examiners. Allowances typically 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:

    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
