A chain of title report is one full ownership history for one patent or application, with every recorded assignment, security interest and release and the title risk flags for that patent. Opening the same patent again within the month does not use another report. Monitoring a patent does not use reports: alerts arrive as new documents are recorded. For a side by side with USPTO certified copies and per-patent vendor prices, see patent chain of title report cost.
The search on the home page runs a real report on any US patent, without an account and without a card. It shows the current owner of record and the first steps of the chain of title, so you can judge the data before you subscribe.
Yes. Move up or down from your account settings. An upgrade applies at once and the difference is prorated. A downgrade applies from the next billing period.
Your searches, exports and monitoring keep working. New chain of title reports resume when the next month starts, or right away when you move to a larger plan.
Yes. Run one report from the search on the home page, without an account and without a card. Assignee itself is a paid subscription with no free tier, so after that one report you pick a plan.
Cancel any time from your account settings. Your plan stays active until the end of the period you paid for and does not renew after that.
Yearly plans are paid up front. Enterprise customers can pay by annual invoice. Write to support@assignee.io for the details.
Firm and Enterprise teams can pull the same records into their own systems with the USPTO assignment API. More answers on US patent search by assignee and the plans in practice on patent analytics software.
