What This Means

With a 12.5% reversal rate, the PTAB affirms the examiner's rejections in the vast majority of cases. This reversal rate is in the bottom 25% across the USPTO, indicating that appeals face significant challenges here.

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, 5.6% of applications that filed an appeal were subsequently allowed. This appeal filing benefit rate is in the bottom 25% across the USPTO, indicating that filing appeals is less effective here than in most other areas.

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 TSANG, HENRY - Prosecution Strategy Guide

Executive Summary

Examiner TSANG, HENRY works in Art Unit 2495 and has examined 407 patent applications in our dataset. With an allowance rate of 78.9%, this examiner has a below-average tendency to allow applications. Applications typically reach final disposition in approximately 29 months.

Allowance Patterns

Examiner TSANG, HENRY's allowance rate of 78.9% places them in the 47% percentile among all USPTO examiners. This examiner has a below-average tendency to allow applications.

Office Action Patterns

On average, applications examined by TSANG, HENRY receive 2.09 office actions before reaching final disposition. This places the examiner in the 55% 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 TSANG, HENRY is 29 months. This places the examiner in the 64% percentile for prosecution speed. Prosecution timelines are slightly faster than average with this examiner.

Interview Effectiveness

Conducting an examiner interview provides a +20.3% benefit to allowance rate for applications examined by TSANG, HENRY. This interview benefit is in the 64% 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, 29.0% of applications are subsequently allowed. This success rate is in the 54% 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 31.0% of cases where such amendments are filed. This entry rate is in the 45% 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, 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 55.6% of appeals filed. This is in the 27% percentile among all examiners. Of these withdrawals, 50.0% 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, 29.2% are granted (fully or in part). This grant rate is in the 17% percentile among all examiners. Strategic Note: Petitions are rarely granted regarding this examiner's actions compared to other examiners. Ensure you have a strong procedural basis before filing a petition, as the Technology Center Director typically upholds this examiner's decisions.

Examiner Cooperation and Flexibility

Examiner's Amendments: This examiner makes examiner's amendments in 0.0% of allowed cases (in the 17% 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 1.2% of allowed cases (in the 63% 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
