PatentRef

Data version 20261027.2, as of 2026-10-28. Free beta.

Triage table

Up to 500 US patents in one table. For each one: its expiry and fee status with the basis, where each component you name sits in its claims, and each independent claim as a list of its parts. Every quote comes with its claim and its offsets in the claim text.

Mark a part have or lacks as your own note. The marks stay in this browser and go into your CSV or JSON export. PatentRef never receives them, and the table describes the patent text only.

Build a table

Each table is one request to the API with your key, one of the requests in its monthly allowance. A table of 500 patents can take up to 20 seconds.

Held by this page while it is open and sent only to this site's API. No key yet? Get a free key.

The patents

One per line, or separated by spaces or commas, with or without US and a kind code: 10905426, US 5,418,943 A, D500396, RE31177.

Up to 12, separated by commas: drive motor, filter bag. With none, the table picks the terms its patents share most.
