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, 57.9% 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

Filing a Notice of Appeal is strategically valuable. The act of filing often prompts favorable reconsideration during the mandatory appeal conference.

Examiner LUU, CHUONG A - Prosecution Strategy Guide

Executive Summary

Examiner LUU, CHUONG A works in Art Unit 2898 and has examined 1,269 patent applications in our dataset. With an allowance rate of 94.2%, this examiner allows applications at a higher rate than most examiners at the USPTO. Applications typically reach final disposition in approximately 18 months.

Allowance Patterns

Examiner LUU, CHUONG A's allowance rate of 94.2% places them in the 83% percentile among all USPTO examiners. This examiner is more likely to allow applications than most examiners at the USPTO.

Office Action Patterns

On average, applications examined by LUU, CHUONG A receive 1.24 office actions before reaching final disposition. This places the examiner in the 22% percentile for office actions issued. This examiner issues significantly fewer office actions than most examiners.

Prosecution Timeline

The median time to disposition (half-life) for applications examined by LUU, CHUONG A is 18 months. This places the examiner in the 95% percentile for prosecution speed. Applications move through prosecution relatively quickly with this examiner.

Interview Effectiveness

Conducting an examiner interview provides a +3.9% benefit to allowance rate for applications examined by LUU, CHUONG A. This interview benefit is in the 25% 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, 37.2% of applications are subsequently allowed. This success rate is in the 81% percentile among all examiners. Strategic Insight: RCEs are highly effective with this examiner compared to others. If you receive a final rejection, filing an RCE with substantive amendments or arguments has a strong likelihood of success.

After-Final Amendment Practice

This examiner enters after-final amendments leading to allowance in 50.2% of cases where such amendments are filed. This entry rate is in the 71% 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, 200.0% result in withdrawal of the rejection or reopening of prosecution. This success rate is in the 97% percentile among all examiners. Strategic Recommendation: Pre-appeal conferences are highly effective with this examiner compared to others. Before filing a full appeal brief, strongly consider requesting a PAC. The PAC provides an opportunity for the examiner and supervisory personnel to reconsider the rejection before the case proceeds to the PTAB.

Appeal Withdrawal and Reconsideration

This examiner withdraws rejections or reopens prosecution in 100.0% of appeals filed. This is in the 95% percentile among all examiners. Of these withdrawals, 61.1% occur early in the appeal process (after Notice of Appeal but before Appeal Brief). Strategic Insight: This examiner frequently reconsiders rejections during the appeal process compared to other examiners. Per MPEP § 1207.01, all appeals must go through a mandatory appeal conference. Filing a Notice of Appeal may prompt favorable reconsideration even before you file an Appeal Brief.

Petition Practice

When applicants file petitions regarding this examiner's actions, 38.2% are granted (fully or in part). This grant rate is in the 36% 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 0.5% of allowed cases (in the 59% 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 2.8% of allowed cases (in the 70% 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:

  • RCEs are effective: This examiner has a high allowance rate after RCE compared to others. If you receive a final rejection and have substantive amendments or arguments, an RCE is likely to be successful.
  • Request pre-appeal conferences: PACs are highly effective with this examiner. Before filing a full appeal brief, request a PAC to potentially resolve issues without full PTAB review.
  • Appeal filing as negotiation tool: This examiner frequently reconsiders rejections during the appeal process. Filing a Notice of Appeal may prompt favorable reconsideration during the mandatory appeal conference.

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
