Filings by year
Technology mix
Compare against all examiners
Eight side-by-side metrics: case volume, pendency, OAs per reexam, rejection mix, SNQ denial rate, certification rate, and PTAB appeal rate, with a Δ column showing where this examiner runs higher or lower than the corpus.
- Average and median pendency, both for this examiner and the corpus
- Rejection basis split (102 / 103 / 112) head-to-head
- Certification, SNQ denial, and PTAB appeal rates
Certificate outcome distribution
How this examiner's certificates split across the six possible outcomes: all claims confirmed, confirmed with amendment, confirmed with new claims, mixed, or all claims canceled. Includes share comparison to the corpus distribution.
- Count and share for each of the six outcome buckets
- Δ vs. corpus distribution in percentage points
- Useful for setting realistic patent-owner expectations
Event-to-event timing
Median time for this examiner's cases at each prosecution stage — filing to first office action, filing to NIRC, and filing to certificate — with corpus comparison and sample size.
- Median in months per transition
- Side-by-side with the corpus median
- n column showing how many of this examiner's cases completed each transition
