What This Means

With a 28.6% reversal rate, the PTAB affirms the examiner's rejections in the vast majority of cases. This reversal rate is below the USPTO average, indicating that appeals face more challenges 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, 27.3% 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 face challenges. Ensure your case has strong merit before committing to full Board review.

Filing a Notice of Appeal shows limited benefit. Consider other strategies like interviews or amendments before appealing.

Examiner SONG, ZHENG B - Prosecution Strategy Guide

Executive Summary

Examiner SONG, ZHENG B works in Art Unit 2875 and has examined 743 patent applications in our dataset. With an allowance rate of 71.7%, this examiner has a below-average tendency to allow applications. Applications typically reach final disposition in approximately 23 months.

Allowance Patterns

Examiner SONG, ZHENG B's allowance rate of 71.7% places them in the 27% percentile among all USPTO examiners. This examiner has a below-average tendency to allow applications.

Office Action Patterns

On average, applications examined by SONG, ZHENG B receive 1.99 office actions before reaching final disposition. This places the examiner in the 65% 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 SONG, ZHENG B is 23 months. This places the examiner in the 77% percentile for prosecution speed. Applications move through prosecution relatively quickly with this examiner.

Interview Effectiveness

Conducting an examiner interview provides a +15.9% benefit to allowance rate for applications examined by SONG, ZHENG B. This interview benefit is in the 60% 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, 22.9% of applications are subsequently allowed. This success rate is in the 21% 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 33.9% of cases where such amendments are filed. This entry rate is in the 42% 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, 100.0% result in withdrawal of the rejection or reopening of prosecution. This success rate is in the 73% percentile among all examiners. Strategic Recommendation: Pre-appeal conferences show above-average effectiveness with this examiner. If you have strong arguments, a PAC request may result in favorable reconsideration.

Appeal Withdrawal and Reconsideration

This examiner withdraws rejections or reopens prosecution in 63.2% of appeals filed. This is in the 37% percentile among all examiners. Of these withdrawals, 41.7% 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, 48.2% are granted (fully or in part). This grant rate is in the 57% 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 25% 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 2.3% of allowed cases (in the 67% 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
