Assignment Agreements In The US: Transfer IP Or Contracts

Maya runs a growing software studio. Her business paid a contractor to build part of its app, bought a small customer list from another company, and is now trying to raise money. When an investor asks, "Do you actually own the code and contract rights?", the paperwork suddenly matters.

That situation is more common than you might think. Transferring IP, receivables or contract rights usually takes more than a handshake, an invoice or an email saying "all good".

The good news is that an assignment agreement can keep the transfer clean. It sets out what is being transferred, when ownership changes hands, what consents are needed, and what happens if the original owner didn't have the right to transfer it.

What Is An Assignment Agreement?

An assignment agreement is a contract that transfers legal rights from one party to another. The party giving up the rights is usually called the assignor, and the party receiving them is the assignee.

For your business, an assignment agreement can be used to transfer things like:

Intellectual property, such as copyright, trademarks, patents, designs, source code, content, artwork, product names and brand assets.
Contract rights, such as the right to receive payment, use a license, enforce a warranty or take over a customer agreement.
Receivables, such as unpaid invoices or accounts receivable assigned to a lender or factoring company.
Business assets, such as domain names, customer records, software documentation or operating materials.

An assignment doesn't always transfer every obligation under a contract. For example, you may be able to assign the right to receive payment, but you may not be able to hand over your obligation to perform services unless the other party agrees. That's where the difference between assignment, delegation and novation matters.

Can You Transfer IP With An Assignment Agreement?

Yes, you can usually transfer IP with an assignment agreement, but the rules depend on the type of IP. A one-line email or invoice often isn't enough, especially for copyright, trademarks and patents.

For US businesses, the federal rules are a key starting point.

Copyright

Under the US Copyright Act, a transfer of copyright ownership generally needs to be in writing and signed by the owner or the owner's authorized agent. This is a big point for software, website copy, photographs, videos, music, marketing content and design work.

If you hire an independent contractor to create a logo, write code or produce a video, don't rely on work-made-for-hire wording alone. A specially ordered or commissioned work is only a work made for hire if it falls within one of the limited statutory categories under the Copyright Act and the parties have a signed written agreement. Many common contractor deliverables, including some logos and software code, may not fit neatly into those categories.

For that reason, contractor agreements should usually include a present copyright assignment as a backup, using an IP assignment clause or separate assignment document. Paying the invoice doesn't automatically mean your business owns the copyright. You may only have an implied license to use the work for the original purpose, which can become a problem if you later want to modify it, resell it, assign it to a buyer or show investors clean ownership.

An assignment should clearly cover:

The specific copyright works being transferred
Whether future updates, source files and drafts are included
The effective date of the transfer
The territory, which is often worldwide
The right to modify, commercialize, sublicense and enforce the rights
Any limits, carve-outs or retained rights

You can also record certain copyright transfers with the US Copyright Office. Recording isn't always required for the assignment to be valid between the parties, but it can help with public notice and priority issues if there are competing claims.

Trademarks

A trademark assignment can transfer a brand name, logo or slogan, but it must transfer the goodwill connected with the mark. Under the Lanham Act, a bare transfer of a trademark without the business goodwill can create serious problems.

In plain English, a trademark isn't just a word or logo sitting by itself. It represents the reputation of your goods or services. If you buy a brand, the assignment should say that the mark is being transferred together with the goodwill of the business connected to that mark.

If the trademark is registered or pending with the USPTO, a trademark transfer can usually be recorded with the USPTO. Be careful with intent-to-use applications. A pending Section 1(b) application generally can't be assigned before use is alleged, unless it's assigned to a successor to the ongoing business connected with the mark. Recording helps keep the public record accurate and can make future sales, licensing, enforcement and financing much smoother.

Patents And Inventions

Patent assignments should also be in writing and are commonly recorded with the USPTO. If your business is buying inventions, technical improvements or patent applications, the agreement should name the invention clearly and include a promise to sign further documents needed for filings or prosecution.

This is especially useful when founders, contractors or technical staff created inventions before the company had proper IP documents in place.

Trade Secrets And Confidential Information

Trade secrets are protected under the federal Defend Trade Secrets Act as well as state law. An assignment can transfer ownership of trade secrets, but confidentiality controls are just as important.

If trade secrets are being transferred, your agreement should cover secure handover, permitted use, return or deletion of copies, employee and contractor access, and ongoing confidentiality obligations. If the information loses its secrecy, it may lose its value.

Can You Assign A Contract To Someone Else?

Sometimes, but it depends on the contract wording and the nature of the rights and obligations. Many contracts let you assign payment rights but restrict transferring the whole contract without consent.

The first place to look is the assignment clause. It may say that:

You can assign the contract freely
You can assign only with the other party's prior written consent
You can assign to an affiliate or buyer of the business without consent
You can't assign at all
Any assignment without consent is void or a breach

Under general US contract principles, rights are often assignable unless the contract says otherwise or the assignment would materially change the other party's burden or risk. State law can change the answer, so you should check the law that governs the contract if the stakes are high.

There's also a practical difference between assigning rights and transferring duties.

Assignment usually transfers a right, such as the right to receive payment.
Delegation transfers performance of a duty, such as delivering services.
Novation replaces one party with another, usually with the consent of all parties.

Say your marketing agency has a 12-month marketing services contract with a client. You sell part of your agency to another company. You may want the buyer to take over the client contract entirely. If the client agreement says no assignment without consent, you'll likely need the client's written consent or a novation. Otherwise, your business may still be on the hook if the buyer doesn't perform.

How Do You Assign Receivables Or Invoices?

You can often assign receivables or invoices, but you need to check the contract, document the transfer clearly and consider UCC filing issues. This comes up often when your business uses invoice factoring, asset-based lending or sells a book of receivables as part of a business sale.

Receivables are usually treated as payment rights. Article 9 of the Uniform Commercial Code often applies to sales and security interests in accounts receivable. The UCC is adopted through state law, so the details can vary, but the core idea is that lenders and buyers may use filings to protect their interest against competing claims.

A receivables assignment should usually cover:

Which invoices or accounts are being assigned
Whether the assignment is an outright sale or security for a loan
The purchase price, advance rate or payment mechanics
Who collects payment from customers
Whether customers must be notified
What happens if a customer disputes the invoice or refuses to pay
Representations that the receivables are valid, unpaid and not already assigned

Without a clear written assignment, you may struggle to prove who owns the receivable, who can collect it, or whether a lender has priority over it.

What Should A US Assignment Agreement Include?

A good assignment agreement should identify the rights being transferred, the price or consideration, the effective date, the required consents and the promises each party is making. The aim is to remove doubt before it becomes a dispute.

Most business assignment agreements should deal with the following points.

Clear Description Of The Assigned Rights

Be specific. Saying "all IP" or "the contract" can be too vague if there are multiple assets, versions or customer agreements.

You may need schedules listing:

Copyright works, source code repositories, files and documentation
Trademark registrations, applications and unregistered marks
Patent applications, invention disclosures and related know-how
Contracts, purchase orders and statements of work
Invoices, accounts and customer payment rights
Domain names, social media handles and business records

Consideration And Payment Terms

The agreement should state what the assignee is giving in exchange. This could be a purchase price, shares, settlement of a debt, ongoing royalties or another agreed benefit.

If payment is conditional, say exactly what needs to happen first. For example, payment might depend on getting a customer's consent, transferring source files, or recording an IP assignment agreement.

Effective Date And Past Rights

The agreement should say when the assignment takes effect. If you need the transfer to cover rights created in the past, say that clearly.

For example, if a contractor built your website over the last 18 months, the assignment should cover the work already created, not just future work.

Representations And Warranties

These are promises about the assigned rights. They're especially important when you're buying assets from someone else.

Common promises include that:

The assignor owns the rights being assigned
The rights haven't already been sold, licensed exclusively or pledged to someone else
The assignor has authority to sign the agreement
The assigned materials don't knowingly infringe someone else's rights
There are no known disputes or unpaid claims affecting the rights

If those promises are wrong, your agreement should say what remedy you have. That could include indemnity wording, refund rights or obligations to fix defects in title.

Consents, Notices And Further Documents

If a contract requires consent to assignment, build that into the process. If an IP office record needs updating, say who will sign and file the documents.

A "further assurances" clause is also helpful. It requires the assignor to sign extra documents or take reasonable steps later if needed to confirm the transfer.

What Can Go Wrong If You Do Not Use One?

Without a written assignment agreement, you may end up with unclear ownership, blocked deals or rights you can't enforce. The issue often appears at the worst time, such as during fundraising, a business sale, a lender review or a customer dispute.

Common problems include:

You paid for work but don't own it. This is common with contractor-created software, designs, content and photos.
A contract can't be transferred. The customer or supplier may refuse consent, or the assignment may breach the original agreement.
The same rights were promised twice. A seller may have already licensed, pledged or assigned the asset to someone else.
Public records don't match reality. USPTO or Copyright Office records may still show the old owner, slowing down enforcement or sale discussions.
Receivables are disputed. A customer may not know who to pay, or a lender may claim priority.
Trade secrets leak during handover. Without confidentiality and access controls, valuable know-how can lose protection.

Templates can be a useful starting point, but assignment documents often need tailoring because the asset, contract wording and consent requirements drive the legal outcome.

How Do You Put An Assignment In Place?

You put an assignment in place by checking ownership, reviewing restrictions, drafting the agreement, getting any required consents and completing any follow-up filings or handover steps. The paperwork doesn't need to be dramatic, but the sequence matters.

Identify the rights. List exactly what you want transferred, including versions, registrations, applications, contracts, invoices and related materials.
Confirm the assignor owns them. Ask for earlier contracts, contractor agreements, employment documents, registration records and proof that no one else has a better claim.
Review restrictions. Check anti-assignment clauses, license limits, financing arrangements and confidentiality obligations.
Get consents where needed. If a customer, supplier, lender or platform needs to approve the transfer, get that approval in writing.
Sign a tailored assignment agreement. Make sure it covers the assets, payment, effective date, warranties, remedies, confidentiality and further documents.
Complete handover. Transfer files, credentials, records, source code, documentation, customer notices and other practical items.
Update official records if relevant. This may include recording assignments with the USPTO or Copyright Office, or making UCC-related filings for receivables and secured transactions.

For example, if your SaaS company buys a small plugin from an independent developer, you would usually need software development and assignment paperwork, not just a bill of sale. You would usually want assignment of copyright in the code, transfer of documentation, confirmation that open-source components are disclosed, confidentiality promises, and help signing any future documents needed to prove ownership.

Frequently Asked Questions

Is An Assignment The Same As A License?

No. An assignment transfers ownership of rights, while a license gives permission to use rights on agreed terms. If you need to own the asset, a license may not be enough.

Does An Assignment Agreement Need To Be Notarized?

Usually no, but notarization may be useful or required for particular filings, counterparties or state-law documents. The bigger issue is usually whether the agreement is written, signed and specific enough.

Can You Assign Future IP?

Often yes, if the agreement is drafted properly. For ongoing work, you may want wording that assigns future-created IP automatically when it's created, plus a backup promise to sign confirmatory documents.

Who Should Sign An Assignment Agreement?

The current owner of the rights and the party receiving them should sign. If a company owns the rights, make sure the person signing has authority to bind that company.

Key Takeaways

An assignment agreement transfers rights from one party to another, but it needs to clearly describe what is being transferred.
IP assignments have specific rules. Copyright transfers generally need a signed writing, contractor work-made-for-hire wording is limited, trademark assignments should include goodwill, and USPTO or Copyright Office records may need updating.
Pending intent-to-use trademark applications need extra care because assignment before use is alleged is restricted.
Contract rights aren't always freely transferable. Check the assignment clause and get written consent where required.
Receivables assignments often involve UCC rules, customer notices and priority issues, especially where lenders are involved.
Clean assignment paperwork can protect your business during fundraising, financing, disputes and business sales.
