Tuan H Nguyen
USPTO Patent Examiner·Active 2012 to 2022
Tuan H Nguyen is a USPTO patent examiner who has handled 21 ex parte reexaminations between 2012 and 2022. These reexams concentrate in Electrical & Electronic, Physics & Instruments, and Mechanical & Manufacturing. ExamPat indexes the full prosecution record for each of these cases, including office-action grounds, certificate outcomes, and downstream PTAB and federal-circuit decisions.
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
