Who Owns the IP When You Hire a Contract Engineer?
In the US, a contract engineer generally owns what they create (code, design files, inventions) until they assign it to you in writing. Paying for the work is not enough, and 'work made for hire' wording alone usually doesn't cover a contractor's firmware or hardware designs. Use a signed agreement with a present assignment of IP. This is general information, not legal advice.
Why paying for it doesn't make it yours
- Copyright starts with the author. For an independent contractor, 'work made for hire' applies only to nine categories listed in the US Copyright Act (contributions to collective works, translations and the like), and only with a signed writing. Firmware and design files generally fall outside them.
- Patent rights start with the inventor. US patent law requires assignments to be in writing, so an invention a contractor conceives stays theirs until it is assigned.
- That is why well-drafted contractor agreements include both work-for-hire language and a backup assignment clause.
- Wording matters: 'hereby assigns' transfers rights now, while 'agrees to assign' can be read as a promise to do it later.
What the agreement should cover
- A clear present assignment of all work product created for you, stating whether it takes effect on signing or on payment.
- Background IP: the contractor's pre-existing libraries, tools and know-how. If any of it ends up in your product, get a perpetual, royalty-free license and list it in the statement of work.
- Open-source and third-party code: require disclosure of every component and its license, including silicon-vendor SDKs that are licensed only for use with that vendor's parts.
- Delivery: native source files, repositories and design data delivered to your systems, not held only on the contractor's.
- Confidentiality that survives the end of the engagement.
Two risks people miss
- Moonlighting: if the contractor also has a full-time job, their employer's invention-assignment agreement may reach side work, especially work related to the employer's business. Ask, and get the answer in writing.
- State laws limit some employer claims (California Labor Code section 2870 is the best known), but those carve-outs generally exclude inventions related to the employer's business.
- Contractors outside the US: assignment rules, and author's rights that can't be fully transferred, vary by country. Get local advice before relying on a US template.
How Talent Badger handles it
- Every specialist signs an IP assignment agreement before work begins, so what they build for you is yours.
- A platform NDA applies from the first conversation, or you can substitute your own.
- Code and design files are delivered into your repositories and systems, under your standards.
Common questions
Not automatically in the US. Copyright belongs to the author and patent rights to the inventor until they are transferred in writing, and contractor-created firmware and design files usually aren't 'work made for hire' by default. A signed agreement with a clear present assignment is what transfers ownership. Have counsel review it.
