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, from 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
