Which companies just got a US patent, and in what technology? Search recent granted patents (PatentsView, CC BY 4.0) by assignee organization (the company), inventor, CPC subclass/section, patent type, or assignee state/country and grant-date window. new_assignee=true isolates patents from an org with its first-ever grant (emerging/stealth signal); flipped_inventor=true finds a patent whose assignee gained an inventor from a prior different assignee (talent move). Public grants, observational.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $1.25.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.govparse.io/v1/patents/search?assignee=openai&assignee_entity=3f6a1c9e-2b4d-4a8e-9c1f-7e2d5a6b8c90&inventor=hinton'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
