Coverage on every plan: US granted patents from 1836 onward and published applications from 2001 onward, searched by keywords, CPC classification, and semantic (meaning-based) retrieval combined. Text of patents granted before 1976 is machine-read (OCR) and may contain errors; those results are labeled. No foreign documents, no US design patents, no US patents granted before 1836 apart from a few surviving earlier patents, and no non-patent literature.
Paid plans start from the app: sign up free, then choose a plan under Plan and billing. Prices exclude tax.
Questions
What do yearly plans include?
Two months free compared with paying monthly. The allowance stays monthly: it resets on the first of each month (UTC) and unused searches or calls do not carry over. API overage on a yearly plan is billed monthly.
What happens past an allowance?
Free and Developer stop at their limit until the month resets. Pro's 1,000 searches are a fair-use limit for one organization's own work. Starter and Scale keep answering and bill each call past the allowance at their per-call rate.
Can I change or cancel?
The organization owner can switch plans or billing period at any time; the difference is prorated on the next invoice. Cancel in the app and the plan stays in effect until the end of the period you paid for. Payments are not refunded except where the law requires it.
How do I pay?
By card on Stripe's checkout page. Card details go to Stripe and never reach ClaimMark. Sales tax is added at checkout where it applies.
We already use ClaimMark-P.
ClaimMark-A Prior Art Search is included for your firm's attorneys and administrators, with Pro's limits, in the same account. API plans are separate.
How good is the search?
We test it in public against the USPTO examiner’s own record, on applications drawn at random, and publish the method, the results, and the misses. Read the study.
Who counts as the organization?
The person who signs up owns the organization and can invite colleagues. Everyone shares the plan and the monthly allowance; each member's search history stays private to them.
