Request the executed rights agreement, amendments, relevant dispute correspondence and any required consent to transfer. Record permitted users, duration, territory, sublicensing and termination provisions. These are review questions for the transaction’s actual documents, not a universal immigration filing checklist. Ask separately for the assignment clause of the underlying licence, since many licences prohibit transfer without the licensor’s written consent. A consent not yet obtained is a condition rather than a formality, and it belongs on the closing checklist with a named owner.
Resolve the meaning of the rights before describing them
A sales brochure may describe proprietary technology while the contract gives only limited access. Have qualified commercial counsel reconcile that difference and explain the rights the U.S. enterprise will hold after closing.
Update the business plan to match the result; do not remove inconvenient restrictions by summarizing the contract more generously. Set the records in a sequence and see whether it closes. The licence grants rights to the seller on stated terms; the assignment or consent moves them to the buyer; the purchase agreement warrants that the move is effective; the disclosure schedule qualifies that warranty.
A break at any link leaves the U.S. enterprise holding less than the brochure described. Where a document in that chain does not exist, ask for it in writing and record the answer rather than assuming it will appear at closing.
