This analysis examines appeal outcomes and the strategic value of filing appeals for examiner WAN, DEMING.
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.
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, 50.0% of applications that filed an appeal were subsequently allowed. This appeal filing benefit rate is in the top 25% across the USPTO, indicating that filing appeals is particularly effective here. The act of filing often prompts favorable reconsideration during the mandatory appeal conference.
⚠ Appeals to PTAB face challenges. Ensure your case has strong merit before committing to full Board review.
✓ Filing a Notice of Appeal is strategically valuable. The act of filing often prompts favorable reconsideration during the mandatory appeal conference.
Examiner WAN, DEMING works in Art Unit 3762 and has examined 28 patent applications in our dataset. With an allowance rate of 85.7%, this examiner has an above-average tendency to allow applications. Applications typically reach final disposition in approximately 31 months.
Examiner WAN, DEMING's allowance rate of 85.7% places them in the 63% percentile among all USPTO examiners. This examiner has an above-average tendency to allow applications.
On average, applications examined by WAN, DEMING receive 2.71 office actions before reaching final disposition. This places the examiner in the 80% percentile for office actions issued. This examiner issues more office actions than most examiners, which may indicate thorough examination or difficulty in reaching agreement with applicants.
The median time to disposition (half-life) for applications examined by WAN, DEMING is 31 months. This places the examiner in the 58% percentile for prosecution speed. Prosecution timelines are slightly faster than average with this examiner.
Conducting an examiner interview provides a +18.8% benefit to allowance rate for applications examined by WAN, DEMING. This interview benefit is in the 61% 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, 14.3% of applications are subsequently allowed. This success rate is in the 10% percentile among all examiners.
