What This Means

With a 33.3% reversal rate, the PTAB reverses the examiner's rejections in a meaningful percentage 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, 21.9% 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 TENTONI, LEO B - Prosecution Strategy Guide

Executive Summary

Examiner TENTONI, LEO B works in Art Unit 1742 and has examined 1,205 patent applications in our dataset. With an allowance rate of 83.6%, this examiner has an above-average tendency to allow applications. Applications typically reach final disposition in approximately 29 months.

Allowance Patterns

Examiner TENTONI, LEO B's allowance rate of 83.6% places them in the 58% percentile among all USPTO examiners. This examiner has an above-average tendency to allow applications.

Office Action Patterns

On average, applications examined by TENTONI, LEO B receive 1.42 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 TENTONI, LEO B is 29 months. This places the examiner in the 63% percentile for prosecution speed. Prosecution timelines are slightly faster than average with this examiner.

Interview Effectiveness

Conducting an examiner interview provides a +9.6% benefit to allowance rate for applications examined by TENTONI, LEO B. This interview benefit is in the 42% 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, 27.8% of applications are subsequently allowed. This success rate is in the 49% 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 62.5% of cases where such amendments are filed. This entry rate is in the 87% percentile among all examiners. Strategic Recommendation: This examiner is highly receptive to after-final amendments compared to other examiners. Per MPEP § 714.12, after-final amendments may be entered "under justifiable circumstances." Consider filing after-final amendments with a clear showing of allowability rather than immediately filing an RCE, as this examiner frequently enters such amendments.

Pre-Appeal Conference Effectiveness

When applicants request a pre-appeal conference (PAC) with this examiner, 33.3% result in withdrawal of the rejection or reopening of prosecution. This success rate is in the 32% percentile among all examiners. Note: Pre-appeal conferences show below-average success with this examiner. Consider whether your arguments are strong enough to warrant a PAC request.

Appeal Withdrawal and Reconsideration

This examiner withdraws rejections or reopens prosecution in 60.0% of appeals filed. This is in the 35% percentile among all examiners. Of these withdrawals, 44.4% 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, 52.2% are granted (fully or in part). This grant rate is in the 52% 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 1.1% of allowed cases (in the 68% 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 19.3% of allowed cases (in the 93% 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:

  • Consider after-final amendments: This examiner frequently enters after-final amendments. If you can clearly overcome rejections with claim amendments, file an after-final amendment before resorting to an RCE.

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
