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 in the top 25% across the USPTO, indicating that appeals are more successful here than in most other areas.

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, 50.0% 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 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 is strategically valuable. The act of filing often prompts favorable reconsideration during the mandatory appeal conference.

Examiner LARGI, MATTHEW THOMAS - Prosecution Strategy Guide

Executive Summary

Examiner LARGI, MATTHEW THOMAS works in Art Unit 3746 and has examined 289 patent applications in our dataset. With an allowance rate of 86.2%, this examiner has an above-average tendency to allow applications. Applications typically reach final disposition in approximately 23 months.

Allowance Patterns

Examiner LARGI, MATTHEW THOMAS's allowance rate of 86.2% places them in the 64% percentile among all USPTO examiners. This examiner has an above-average tendency to allow applications.

Office Action Patterns

On average, applications examined by LARGI, MATTHEW THOMAS receive 1.76 office actions before reaching final disposition. This places the examiner in the 38% 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 LARGI, MATTHEW THOMAS is 23 months. This places the examiner in the 88% percentile for prosecution speed. Applications move through prosecution relatively quickly with this examiner.

Interview Effectiveness

Conducting an examiner interview provides a +18.2% benefit to allowance rate for applications examined by LARGI, MATTHEW THOMAS. 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, 27.1% of applications are subsequently allowed. This success rate is in the 46% percentile among all examiners. Strategic Insight: RCEs show below-average effectiveness with this examiner. Carefully evaluate whether an RCE or continuation is the better strategy.

After-Final Amendment Practice

This examiner enters after-final amendments leading to allowance in 46.2% of cases where such amendments are filed. This entry rate is in the 70% 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 22% 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 50.0% of appeals filed. This is in the 21% percentile among all examiners. Strategic Insight: This examiner rarely withdraws rejections during the appeal process compared to other examiners. If you file an appeal, be prepared to fully prosecute it to a PTAB decision. Per MPEP § 1207, the examiner will prepare an Examiner's Answer maintaining the rejections.

Petition Practice

When applicants file petitions regarding this examiner's actions, 20.0% are granted (fully or in part). This grant rate is in the 10% 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 44% 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 8.8% of allowed cases (in the 87% percentile). Per MPEP § 714.14, a Quayle action indicates that all claims are allowable but formal matters remain. This examiner frequently uses Quayle actions compared to other examiners, which is a positive indicator that once substantive issues are resolved, allowance follows quickly.

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
