This analysis examines appeal outcomes and the strategic value of filing appeals for examiner MARIEN, ANDREW JAMES.
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.
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, 20.0% of applications that filed an appeal were subsequently allowed. This appeal filing benefit rate is in the bottom 25% across the USPTO, indicating that filing appeals is less effective here than in most other areas.
✓ 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 shows limited benefit. Consider other strategies like interviews or amendments before appealing.
Examiner MARIEN, ANDREW JAMES works in Art Unit 3745 and has examined 264 patent applications in our dataset. With an allowance rate of 81.1%, this examiner has a below-average tendency to allow applications. Applications typically reach final disposition in approximately 27 months.
Examiner MARIEN, ANDREW JAMES's allowance rate of 81.1% places them in the 45% percentile among all USPTO examiners. This examiner has a below-average tendency to allow applications.
On average, applications examined by MARIEN, ANDREW JAMES receive 1.66 office actions before reaching final disposition. This places the examiner in the 46% percentile for office actions issued. This examiner issues fewer office actions than average, which may indicate efficient prosecution or a more lenient examination style.
The median time to disposition (half-life) for applications examined by MARIEN, ANDREW JAMES is 27 months. This places the examiner in the 59% percentile for prosecution speed. Prosecution timelines are slightly faster than average with this examiner.
Conducting an examiner interview provides a +13.3% benefit to allowance rate for applications examined by MARIEN, ANDREW JAMES. This interview benefit is in the 54% percentile among all examiners. Recommendation: Interviews provide an above-average benefit with this examiner and are worth considering.
When applicants file an RCE with this examiner, 31.9% of applications are subsequently allowed. This success rate is in the 58% 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.
This examiner enters after-final amendments leading to allowance in 46.3% of cases where such amendments are filed. This entry rate is in the 65% 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.
When applicants request a pre-appeal conference (PAC) with this examiner, 133.3% result in withdrawal of the rejection or reopening of prosecution. This success rate is in the 86% percentile among all examiners. Strategic Recommendation: Pre-appeal conferences are highly effective with this examiner compared to others. Before filing a full appeal brief, strongly consider requesting a PAC. The PAC provides an opportunity for the examiner and supervisory personnel to reconsider the rejection before the case proceeds to the PTAB.
This examiner withdraws rejections or reopens prosecution in 77.8% of appeals filed. This is in the 66% percentile among all examiners. Of these withdrawals, 57.1% 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.
When applicants file petitions regarding this examiner's actions, 47.1% are granted (fully or in part). This grant rate is in the 54% 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's Amendments: This examiner makes examiner's amendments in 0.0% of allowed cases (in the 39% 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 1.9% of allowed cases (in the 64% percentile). This examiner issues Quayle actions more often than average when claims are allowable but formal matters remain (MPEP § 714.14).
