◈ FIND YOUR PATENT EXAMINER

USPTO examiner lookup.

Who is my patent examiner?

Enter your U.S. application, patent, or publication number and we'll look up the assigned USPTO examiner from public USPTO data — and, where we've loaded that technology center, their allowance rate, rejection profile, and pendency. Already know the examiner? Type their name instead and go straight to their page.

Type an examiner name to jump straight to their page, or enter an application (18/123,456), patent (US 10,617,218), or publication (US 2019/0075929 A1) number — with or without dashes, slashes, or commas.

Your number is used only to run this lookup. We accept an application number (e.g. 18/123,456), a patent number (e.g. US 10,617,218), or a publication number (e.g. US 2019/0075929 A1) — with or without the slash and comma. Or skip the number and type an examiner's name.
