This report shows what is recorded at the USPTO. Assignments that were never recorded do not appear in any public register. It is not legal advice.

Every recorded document, read and put in order

Every patent carries a history of recorded documents. Assignee reads all of them, so the owner of record is never a guess.

Every transfer, from inventor to buyer

Follow each transfer from inventor to employer to buyer, with the reel and frame of every recorded document.

Liens that were never released

See open security interests before you buy, license or lend against a patent.

Inventors who never signed over their rights

This is the gap that most often breaks a chain of title, and Assignee spots it.

Old company names linked to the current owner

A merger can leave the register under a name that no longer exists. Assignee links that name to the company that owns the patent today.

From raw records to a clean chain of title

The patent assignment database at the USPTO stores conveyances as separate records. Assignee turns them into one readable history in three steps. Teams with a whole schedule to check use bulk patent assignment lookup.

1. We pull every recorded conveyance

Assignee fetches the assignment records the USPTO holds for the patent and its application, including documents recorded against the application before grant.

2. We link assignors to assignees

Each record is matched to the one before it, so you see who passed the rights to whom, when the document was signed and when it was recorded.

3. We flag what breaks the title

Rules check the chain for missing inventor assignments, open security interests, name changes without a transfer and gaps between owners. The result is a report you can export.

A fast, documented answer for whoever signs off

Every patent lawsuit, license, acquisition and loan turns on who owns the patent. Assignee answers that question for the people who approve the deal.

Hours of paralegal work become one report

Rebuilding a chain of title by hand means opening each reel and frame, matching names and drawing the timeline. Assignee returns the same timeline in seconds, with a link to every source document.

Fewer surprises at closing and in court

A missing inventor assignment or an unreleased lien can stop an infringement case on standing or delay a closing. Title risk flags show these issues before the other side does.

A portfolio that watches itself

Add your patents, your licensors or a target portfolio to patent monitoring and get an email whenever a new assignment or security interest is recorded.

Example. Before a licensing call, you enter the patent number. Assignee shows that the patent moved from the inventors to a startup, then to a holding company after an acquisition. It also shows a 2019 security interest that still has no recorded release. You know who has to sign and what to ask before the call starts.

Questions before you start

Read all questions

Is this the same data as the USPTO?

Yes. Assignee uses the assignment records the USPTO publishes for every patent and application. We read the same conveyances, link them in order and show them as one chain of title, with the reel and frame of each document so you can open the original.

How current is the ownership?

Ownership is shown as of the latest document recorded at the USPTO. An assignment that was signed but never recorded does not appear in any public register, and the report says so plainly.

Can I rely on it for litigation or a closing?

Assignee gives you a documented starting point. Every entry links to its recorded document, so your attorney can verify each step. The report is not legal advice and does not replace a title opinion.

Do you cover patents outside the US?

Assignee covers US patents and US applications recorded at the USPTO. Foreign family members are outside the register we read.

Who sees my searches?

Only your account and the teammates you invite. We do not sell or share the patents you search or monitor.

Can my team share matters, and do you support SSO and annual invoicing?

Professional and Firm plans include shared matter folders. Firm adds roles and permissions. Enterprise adds SSO with SAML, an audit log and annual invoicing.

How do I cancel?

Cancel any time from your account settings. Your plan stays active until the end of the period you paid for.
