The most expensive intellectual property mistakes are rarely about protection. They are about ownership — a company discovers, usually during a financing or a sale, that the logo, the codebase, or the core invention belongs to someone who was paid to create it but never signed anything transferring it.
Paying for creative work does not transfer copyright. Neither does calling a contract a "work for hire agreement." U.S. law sets out two narrow routes by which someone other than the creator owns a copyright from the start, and one general route for transferring it afterwards. Patents follow different rules again, and trademarks a third set. Getting this right is mostly a matter of knowing which of the three you are dealing with.
Key takeaways
- Under 17 U.S.C. § 101, a work made for hire is either work by an employee within the scope of employment, or a specially commissioned work in one of nine listed categories with a signed written agreement.
- Software, most logos, photographs, and general design work are not on the nine-category list. For those, work-for-hire language does nothing and a written assignment is required.
- Patent rights begin with the inventors as individuals. A company owns them only through an assignment, and present-tense assignment language works better than a promise to assign later.
- Assignments should be recorded — copyright transfers with the Copyright Office, patent and trademark assignments with the USPTO — to protect priority against later purchasers.
- Several states limit how far employee invention-assignment clauses can reach into work done on the employee's own time with their own resources.
Work made for hire: two routes, both narrow
When a work is made for hire, the hiring party is the author from the moment of creation. There is no transfer, nothing to record, and no later termination right. That is a considerable advantage — which is why the statute limits it carefully.
Route one: employees within the scope of employment
Work prepared by an employee within the scope of employment is a work made for hire automatically, with no signature required. The difficulty is that "employee" here means employee in the legal sense, decided by common-law agency factors: control over how the work is done, provision of tools and workspace, method of payment, tax treatment, benefits, duration of the relationship, and whether the work is part of the hiring party's regular business.
Those are close cousins of the tests discussed in our guide to employee and independent contractor classification. A worker labelled a contractor for tax purposes but treated like an employee may or may not be one for copyright purposes, and the answer is fact-driven. Companies should not rely on the employee route for anyone whose status is genuinely ambiguous.
Route two: nine categories and a signature
For specially ordered or commissioned work, the statute lists exactly nine eligible categories:
- A contribution to a collective work
- A part of a motion picture or other audiovisual work
- A translation
- A supplementary work
- A compilation
- An instructional text
- A test
- Answer material for a test
- An atlas
Both conditions must be met: the work must fall in one of the nine categories, and the parties must expressly agree in a written instrument signed by them that the work is a work made for hire.
Practical note: Scan that list for software. It is not there. Nor is a logo, a marketing website, a photograph taken on commission, or a standalone illustration. Contracts that say "all deliverables shall be works made for hire" and stop there leave the commissioning party with nothing but an implied licence for a large share of ordinary creative work.
Assignments: the general-purpose fix
Where work-for-hire does not apply, ownership moves by assignment. A transfer of copyright ownership must be in writing and signed by the person conveying the right. That is the whole formal requirement, but several drafting details decide whether the clause actually works.
- Use present-tense operative language — "hereby assigns" — rather than a promise to assign in the future, which may only create a contract right requiring further action.
- Include a belt-and-braces work-for-hire clause first, with an assignment that applies "to the extent any deliverable is not a work made for hire."
- Define the deliverables and the scope: all work created in connection with the engagement, including drafts, source files, and preliminary materials.
- Address pre-existing and third-party material separately, with a licence broad enough to use the deliverable as intended.
- Add a further-assurances covenant obliging the creator to sign recordation documents and patent papers later.
- Include waivers of moral rights where applicable, since works of visual art carry attribution and integrity rights that can only be waived in a signed writing.
- Confirm the signer has authority — a contractor's own employees or subcontractors must have assigned rights upstream.
Patents start with people, not companies
U.S. patent law vests initial rights in the human inventors, regardless of who funded the work or who employs them. A company obtains ownership only through assignment. There is no patent equivalent of work made for hire.
Two practical consequences follow. First, employment agreements should include a present assignment of inventions conceived during employment, not merely an obligation to assign. Federal courts have drawn a meaningful distinction between the two formulations, and companies have lost rights over the difference. Second, joint inventors each own an undivided interest in the whole patent absent agreement, and in the U.S. each co-owner can generally license or use the invention without accounting to the others. A single unassigned co-inventor can therefore undermine an entire exclusivity position.
Assignments should be executed early — ideally at hiring and again at the time each application is filed — and recorded with the USPTO. Recording within the statutory window protects the assignee against a subsequent purchaser without notice. The mechanics of filing and prosecuting the underlying applications are covered in our guide to responding to office actions.
| Right | Initial owner | Transfer requirement | Where to record |
|---|---|---|---|
| Copyright | The author — or the hiring party if work made for hire | Signed writing by the transferring party | U.S. Copyright Office (optional but protective) |
| Patent | The named inventors individually | Written assignment; present-tense language preferred | USPTO Assignment Center |
| Trademark | The user of the mark in commerce | Written assignment including the associated goodwill | USPTO Assignment Center |
| Trade secret | The owner of the confidential information | Contract; governed by agreement and state law | Not recorded — protected by confidentiality practice |
Trademarks add their own trap. A trademark assignment must carry the goodwill of the business associated with the mark. An assignment stripped of goodwill — an "assignment in gross" — can be invalid, which is one reason brand transfers usually list associated customer lists, recipes, specifications, or supply arrangements alongside the registration itself. Related risks appear in our guide to trademark licensing and quality control.
State limits on employee invention assignments
Broad invention-assignment clauses run into state statutes. Several states — California among the earliest, with similar provisions in Washington, Illinois, Minnesota, and others — limit an employer's claim to inventions the employee developed entirely on their own time, without using the employer's equipment, supplies, facilities, or trade secret information, and that do not relate to the employer's business or anticipated research or result from work performed for the employer.
These statutes often require the employer to give written notice of the limitation when the agreement is signed. Because the details and the notice requirements vary, multi-state employers should confirm the rule in each state where employees work rather than using one national form unchanged. Remote and distributed teams make this more complicated, not less — an issue that also affects wage, tax, and leave obligations, as our article on remote work across state lines discusses.
The 35-year termination right
Copyright law gives authors and their heirs a right to terminate transfers and licences made on or after January 1, 1978, during a five-year window that generally opens 35 years after the grant. Termination requires advance written notice recorded with the U.S. Copyright Office within specified time limits, and the right cannot be waived by contract.
Works made for hire are excluded, because there was never a transfer to terminate. For long-lived assets — a character, a musical catalogue, a foundational software library assigned by a founder before incorporation — the difference matters decades later, and it is one of the reasons diligence teams look hard at how early rights were acquired.
Example (hypothetical): Two founders build a prototype before forming their company, hiring a freelance designer for the logo and a contractor for the initial codebase. Neither signs an assignment. Three years later, an acquirer's diligence flags that the company does not own its brand or its earliest code. Both creators are traceable and cooperative — but each now has leverage, and the fix costs more than a lawyer would have charged at the start.
Frequently asked questions
If I paid for it, don't I own it?
Not automatically. Payment buys the deliverable, not the copyright. Absent a written assignment or a valid work-for-hire arrangement, the creator generally retains ownership and the paying party has at most an implied licence to use the work for the purpose it was commissioned for. That licence rarely covers modification, resale, or exclusive use.
Can a work-for-hire clause and an assignment both go in the same contract?
Yes, and they should. The standard structure states that deliverables are works made for hire to the extent permitted by law, and then assigns all rights in anything that does not qualify. The assignment is what actually does the work in most software, design, and photography engagements, but the work-for-hire clause costs nothing and helps where it applies.
Do we need a new assignment for every project?
Not necessarily. A master services agreement with a present assignment covering all work under future statements of work is usually sufficient, provided the scope language is broad enough. What matters is that the signature predates or accompanies the work and that the language operates on rights as they come into existence rather than promising a later transfer.
Should copyright assignments be recorded?
Recording is optional but useful. A recorded transfer gives constructive notice of the assignee's claim and helps establish priority against a conflicting later transfer. It also creates a public chain of title that buyers and lenders can verify. Registration of the underlying work is a separate step and is generally required before filing an infringement suit.
What about work created with AI tools?
The Copyright Office has taken the position that copyright protects human authorship and that purely machine-generated output is not registrable, while works with sufficient human authorship may be registered with the AI-generated portions disclosed. Because guidance in this area continues to develop, check the Copyright Office's current registration guidance before relying on a position, and keep records of the human contribution.
Cleaning up the chain of title
Ownership problems compound quietly and surface at the worst possible moment. The cure is unglamorous: a standing form that every employee signs at hire, a contractor agreement nobody is allowed to waive, a register of every externally created asset with a link to the signed paper, and recordation of assignments as they happen rather than in a pre-deal scramble.
If gaps already exist, fix them while relationships are good and leverage is even. Confirmatory assignments from past contractors are usually straightforward when asked politely and early. What they are not is cheap once a buyer has identified them, which is exactly the scenario mapped out in our guide to IP due diligence in transactions.
