What This Means

With a 100.0% reversal rate, the PTAB has reversed the examiner's rejections more often than affirming them. 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, 44.4% of applications that filed an appeal were subsequently allowed. This appeal filing benefit rate is above the USPTO average, suggesting that filing an appeal can be an effective strategy for prompting reconsideration.

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 HOLLAND, DERRICK EDWARD - Prosecution Strategy Guide

Executive Summary

Examiner HOLLAND, DERRICK EDWARD works in Art Unit 2912 and has examined 3,153 patent applications in our dataset. With an allowance rate of 99.1%, this examiner allows applications at a higher rate than most examiners at the USPTO. Applications typically reach final disposition in approximately 13 months.

Allowance Patterns

Examiner HOLLAND, DERRICK EDWARD's allowance rate of 99.1% places them in the 93% 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 HOLLAND, DERRICK EDWARD receive 0.26 office actions before reaching final disposition. This places the examiner in the 1% 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 HOLLAND, DERRICK EDWARD is 13 months. This places the examiner in the 99% percentile for prosecution speed. Applications move through prosecution relatively quickly with this examiner.

Interview Effectiveness

Conducting an examiner interview provides a -2.3% benefit to allowance rate for applications examined by HOLLAND, DERRICK EDWARD. This interview benefit is in the 8% percentile among all examiners. Note: Interviews show limited statistical benefit with this examiner compared to others, though they may still be valuable for clarifying issues.

Request for Continued Examination (RCE) Effectiveness

When applicants file an RCE with this examiner, 54.5% of applications are subsequently allowed. This success rate is in the 98% 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 92.9% of cases where such amendments are filed. This entry rate is in the 98% 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 90.0% of appeals filed. This is in the 83% percentile among all examiners. Of these withdrawals, 66.7% 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, 50.9% are granted (fully or in part). This grant rate is in the 50% 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 26.4% of allowed cases (in the 99% percentile). Per MPEP § 1302.04, examiner's amendments are used to place applications in condition for allowance when only minor changes are needed. This examiner frequently uses this tool compared to other examiners, indicating a cooperative approach to getting applications allowed. Strategic Insight: If you are close to allowance but minor claim amendments are needed, this examiner may be willing to make an examiner's amendment rather than requiring another round of prosecution.

Quayle Actions: This examiner issues Ex Parte Quayle actions in 15.3% of allowed cases (in the 92% 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.
  • 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.
  • Examiner cooperation: This examiner frequently makes examiner's amendments to place applications in condition for allowance. If you are close to allowance, the examiner may help finalize the claims.
