Assignee

Patent due diligence reports in minutes

Patent due diligence checks whether the patents in a deal are owned by the seller, free of undisclosed liens and supported by a complete chain of title. Assignee produces that part of the review from the public record in minutes, for one patent or a whole portfolio through bulk patent assignment lookup, with every source document linked.

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.

The ownership checklist in a patent due diligence

  • Is the seller the owner of record of every patent on the schedule
  • Did every inventor assign to the original owner, and is it recorded
  • Does each transfer connect to the one before it
  • Were mergers and name changes recorded as transfers to the current entity
  • Are there security interests, and were they released
  • Were any patents already sold, partly assigned or recorded to someone else
  • Do the names on the schedule match the names in the record

Assignee answers each of these for every patent and flags the ones that fail.

What the due diligence report contains

Part Content
Portfolio summary Patents checked, owner of record of each, patents with flags
Owner match Where the record agrees and disagrees with the seller's schedule
Chain of title Full recorded history of every patent

Flags Each title risk with the document behind it
Sources Links to every recorded document

Export as PDF for the data room memo or as Excel on the Firm plan for your own review. When the schedule runs to dozens of patents, start with a patent ownership audit across the whole portfolio and send only the exceptions to counsel.

Where the report is used

  • Acquisitions of companies whose value sits in their patents
  • Purchases of individual patents or portfolios, see sell my patent
  • Loans and financing secured by patents
  • Exclusive licenses and licensing programs, see patent licensing
  • Investments in technology companies
  • Litigation funding decisions

What it does not replace

The report covers recorded ownership and liens. It does not judge validity, claim scope or infringement, and it cannot show transfers that were never recorded. Counsel still reviews the agreements in the data room. Assignee makes sure they start with a correct and complete picture of the record. For value questions, see patent valuation.

For deal teams

Put the target portfolio in a shared matter folder, give access to the people on the deal and keep it under patent monitoring until closing, so a new recording does not surprise you on the closing date.
