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, 33.3% 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 SMITH, CHAD - Prosecution Strategy Guide

Executive Summary

Examiner SMITH, CHAD works in Art Unit 2874 and has examined 979 patent applications in our dataset. With an allowance rate of 80.8%, this examiner has an above-average tendency to allow applications. Applications typically reach final disposition in approximately 24 months.

Allowance Patterns

Examiner SMITH, CHAD's allowance rate of 80.8% places them in the 51% percentile among all USPTO examiners. This examiner has an above-average tendency to allow applications.

Office Action Patterns

On average, applications examined by SMITH, CHAD receive 1.75 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 SMITH, CHAD is 24 months. This places the examiner in the 83% percentile for prosecution speed. Applications move through prosecution relatively quickly with this examiner.

Interview Effectiveness

Conducting an examiner interview provides a +15.8% benefit to allowance rate for applications examined by SMITH, CHAD. This interview benefit is in the 56% 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, 32.9% of applications are subsequently allowed. This success rate is in the 70% percentile among all examiners. Strategic Insight: RCEs show above-average effectiveness with this examiner. Consider whether your amendments or new arguments are strong enough to warrant an RCE versus filing a continuation.

After-Final Amendment Practice

This examiner enters after-final amendments leading to allowance in 38.7% of cases where such amendments are filed. This entry rate is in the 59% 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, 46.2% result in withdrawal of the rejection or reopening of prosecution. This success rate is in the 41% 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 75.8% of appeals filed. This is in the 67% percentile among all examiners. Of these withdrawals, 48.0% occur early in the appeal process (after Notice of Appeal but before Appeal Brief). Strategic Insight: This examiner shows above-average willingness to reconsider rejections during appeals. The mandatory appeal conference (MPEP § 1207.01) provides an opportunity for reconsideration.

Petition Practice

When applicants file petitions regarding this examiner's actions, 68.8% are granted (fully or in part). This grant rate is in the 76% 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 7.0% of allowed cases (in the 89% 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 6.8% of allowed cases (in the 84% 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:

  • 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.

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
