Patent examiner statistics, free for every USPTO examiner.
Allowance rates, difficulty, rejection patterns, interview and RCE effectiveness, and contact details, computed from USPTO Patent Center (formerly PAIR). Then turn that history into your office action response inside AI Studio.
Look up any USPTO patent examiner
A patent examiner's allowance rate is the share of their disposed applications that issue as patents. Across the USPTO it runs from under 20% to over 95%, so looking up your examiner, their rejection patterns, and how interviews and RCEs have performed on their docket is the fastest way to read the odds before you respond to an office action.
Source USPTO Patent Center (formerly PAIR). Public profiles use filing years 2021 to 2025, updated monthly. The full dataset in AI Studio covers 6+ years.

Just got an office action. Put your examiner's history to work.
The free profiles show you how an examiner rules. AI Studio helps you respond. Open your office action in the office action response workflow and draft with this examiner's and art unit's record in view, the rejections they issue, the arguments that have overcome them, and how interviews and RCEs have actually played out on their docket.
Takes the examiner into account
Every response starts from how this examiner and art unit have ruled, not generic boilerplate.
Ask anything about your examiner
AI Studio reads the full prosecution dataset behind these profiles, so you can interrogate the patterns in plain English.
Weigh your options with the data
Weigh an interview, an RCE, or a claim amendment against what has actually worked on this docket.
Included with your free trial.
Historical patterns shown for general information. This is not legal advice and does not predict the outcome of any application. Decisions about interviews, RCEs, and claim strategy rest with you and a licensed patent attorney or agent.
The full examiner dataset behind every profile
The public profiles are a slice. The complete Prosecution Intel dataset powers your AI Studio drafts and is searchable on its own, computed from USPTO file wrappers, not scraped summaries.
