This analysis examines appeal outcomes and the strategic value of filing appeals for examiner CHRISTENSEN, DANIELLE M.
With a 11.1% 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.
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, 22.2% 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.
⚠ 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 CHRISTENSEN, DANIELLE M works in Art Unit 3745 and has examined 641 patent applications in our dataset. With an allowance rate of 80.8%, this examiner has a below-average tendency to allow applications. Applications typically reach final disposition in approximately 33 months.
Examiner CHRISTENSEN, DANIELLE M's allowance rate of 80.8% places them in the 44% percentile among all USPTO examiners. This examiner has a below-average tendency to allow applications.
On average, applications examined by CHRISTENSEN, DANIELLE M receive 1.77 office actions before reaching final disposition. This places the examiner in the 53% percentile for office actions issued. This examiner issues a slightly above-average number of office actions.
The median time to disposition (half-life) for applications examined by CHRISTENSEN, DANIELLE M is 33 months. This places the examiner in the 29% percentile for prosecution speed. Prosecution timelines are slightly slower than average with this examiner.
Conducting an examiner interview provides a +8.4% benefit to allowance rate for applications examined by CHRISTENSEN, DANIELLE M. This interview benefit is in the 41% percentile among all examiners. Recommendation: Interviews provide a below-average benefit with this examiner.
When applicants file an RCE with this examiner, 25.3% of applications are subsequently allowed. This success rate is in the 30% 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.
This examiner enters after-final amendments leading to allowance in 55.0% of cases where such amendments are filed. This entry rate is in the 77% 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.
When applicants request a pre-appeal conference (PAC) with this examiner, 25.0% result in withdrawal of the rejection or reopening of prosecution. This success rate is in the 27% 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.
This examiner withdraws rejections or reopens prosecution in 41.9% of appeals filed. This is in the 5% percentile among all examiners. Of these withdrawals, 15.4% occur early in the appeal process (after Notice of Appeal but before Appeal Brief). Strategic Insight: This examiner rarely withdraws rejections during the appeal process compared to other examiners. If you file an appeal, be prepared to fully prosecute it to a PTAB decision. Per MPEP § 1207, the examiner will prepare an Examiner's Answer maintaining the rejections.
When applicants file petitions regarding this examiner's actions, 47.4% are granted (fully or in part). This grant rate is in the 55% 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 0.2% of allowed cases (in the 48% 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 0.4% of allowed cases (in the 48% percentile). This examiner issues Quayle actions less often than average. Allowances may come directly without a separate action for formal matters.
