Who published the data on this page
- Practitioner roster: USPTO Office of Enrollment and Discipline bulk roster download, read fresh at each site build. See SOURCES.md for the licence terms quoted from that page.
What this page cannot tell you
- We show organizations only. We never publish a registered practitioner's own name, home address, or phone number, even when the roster lists one.
- Firm names are grouped by spelling after light punctuation cleanup, not by any legal-entity check: “Acme Inc” and “Acme, Inc.” are folded together, but two unrelated firms that happen to share a name are not told apart.
- Our automatic test for “this reads as a person's own name, not a firm” is imperfect. It correctly protects solo practitioners, and it also mistakenly withholds a small number of real company names (for example “Boston Scientific” and “GE Healthcare”); those counts are folded into Individual practitioners along with everyone who listed no firm.
- The USPTO updates its roster on its own schedule; our copy is only as current as the date stamped on this page.
- Registration to practice before the USPTO is not the same as being licensed to practice law in any state, and a listing here is not a recommendation.
- A firm's count here is only its USPTO-registered patent attorneys and agents at this city; it says nothing about the firm's total headcount or its non-patent practice.
See the file before you pay
You do not have to take our word for what is in the file. Here are 25 rows of the real thing, carrying all 3 of its columns, cut out of the dated copies we sealed ourselves. Nothing in it is made up and nothing in it is tidied up.
- Open the 25 rows as a CSVA plain spreadsheet file. It saves to your machine rather than painting itself into a browser tab, and it opens in Excel, Numbers or Google Sheets.
- The same 25 rows as JSONThe same rows again, laid out for reading with code.
What arrives after you pay: a person emails you what you asked for as a CSV — the same plain spreadsheet as the sample file above, not a login and not a web page — within one working day of your payment.
What you would be paying for: $350 for a 12-month Featured listing in one city, naming your firm and website at the top of that city's page. One Featured firm per city; if the city you name already has a Featured firm when we process this, nothing runs and the payment is refunded on request within 14 days. Records may lag the source roster by up to one site build. After you pay we email you within one working day to confirm the city and firm name; the listing goes live within 15 minutes of payment. Still not there after 15 minutes? Reply to your Stripe receipt.
These 25 rows are a slice of the file, not the whole of it. What we cannot show you here is how far back it goes: that is the part you are paying for.
