What This Means

With a 0.0% 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, 26.3% 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 ROZOF, TIMOTHY R - Prosecution Strategy Guide

Executive Summary

Examiner ROZOF, TIMOTHY R works in Art Unit 1625 and has examined 1,568 patent applications in our dataset. With an allowance rate of 82.0%, this examiner has an above-average tendency to allow applications. Applications typically reach final disposition in approximately 16 months.

Allowance Patterns

Examiner ROZOF, TIMOTHY R's allowance rate of 82.0% places them in the 54% percentile among all USPTO examiners. This examiner has an above-average tendency to allow applications.

Office Action Patterns

On average, applications examined by ROZOF, TIMOTHY R receive 0.79 office actions before reaching final disposition. This places the examiner in the 5% 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 ROZOF, TIMOTHY R is 16 months. This places the examiner in the 98% percentile for prosecution speed. Applications move through prosecution relatively quickly with this examiner.

Interview Effectiveness

Conducting an examiner interview provides a +23.5% benefit to allowance rate for applications examined by ROZOF, TIMOTHY R. This interview benefit is in the 70% 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, 42.4% of applications are subsequently allowed. This success rate is in the 94% 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 50.3% of cases where such amendments are filed. This entry rate is in the 76% 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.

Appeal Withdrawal and Reconsideration

This examiner withdraws rejections or reopens prosecution in 92.3% of appeals filed. This is in the 84% percentile among all examiners. Of these withdrawals, 83.3% 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, 69.5% are granted (fully or in part). This grant rate is in the 77% percentile among all examiners. Strategic Note: Petitions are frequently granted regarding this examiner's actions compared to other examiners. Per MPEP § 1002.02(c), various examiner actions are petitionable to the Technology Center Director, including prematureness of final rejection, refusal to enter amendments, and requirement for information. If you believe an examiner action is improper, consider filing a petition.

Examiner Cooperation and Flexibility

Examiner's Amendments: This examiner makes examiner's amendments in 0.8% of allowed cases (in the 65% 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 0.2% of allowed cases (in the 52% 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:

  • 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.
  • 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.
  • 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
