PatentRef runs on your own machine — the client starts it, so there is no endpoint to ping. 372 installs a week from pypi.
PatentsView-compatible US patent API: claim trees, patent briefs and search, grants 1976 to now.
Today is the operative word: we check PatentRef every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
