Inventors ask this expecting a checkbox on the USPTO form. There isn't one. Under US law a patent application must name the natural persons who conceived the invention — an LLC cannot conceive anything, and listing a company as inventor is a defect that can invalidate the patent. What you actually choose is who owns the patent, and ownership is a separate legal act from inventorship. Getting that distinction right early saves a scramble later, usually during due diligence, when a buyer or investor asks for a clean chain of title and finds one missing.

What follows is how the mechanics work in practice. It is not legal advice, and the right structure depends on your tax situation, your state, and your funding plans — talk to a patent attorney and a business attorney before filing.

Inventorship and Ownership Are Two Different Things

Inventorship is a factual question: who contributed to the conception of at least one claim? Get it wrong and the patent is vulnerable. Adding your business partner who funded the work but contributed nothing technical is inventorship fraud. Omitting an engineer who solved the key problem is equally dangerous, and the rules around shared credit are laid out in how co-ownership of a patent actually works.

Ownership starts with the inventors by default. Each named inventor owns an undivided interest in the whole patent and, absent an agreement, can license it independently without accounting to the others. That default is almost always undesirable, which is why ownership gets moved deliberately.

The Assignment Is the Whole Mechanism

A patent assignment is a written transfer of ownership from the inventors to whoever should hold the asset. It can be executed before filing, at filing, or years afterward, and it gets recorded with the USPTO — currently a modest electronic recordation fee, often zero for standard electronic submissions. Recording is not required for the transfer to be valid between the parties, but an unrecorded assignment can be defeated by a later bona fide purchaser. The full sequence is in how patent ownership actually transfers.

The practical version: you file naming yourself as inventor, and you sign an assignment conveying the application and any patents issuing from it to your LLC or corporation. The application then lists the company as applicant and assignee. Nothing about this changes who is credited as the inventor.

Why Entity Ownership Is Usually the Right Default

Liability separation

If the patent sits in your personal name and you personally sue an infringer, you are personally exposed to a counterclaim — invalidity, inequitable conduct, antitrust, or a declaratory judgment action that can cost six figures to defend. Holding the asset in an entity keeps that fight at the entity level. It is the same reasoning that drives the entity choice itself, discussed in LLC versus sole proprietorship for inventors.

Financing and diligence

Investors buy the company, not you. If the core IP sits outside the entity and is merely licensed in, every term sheet will include a condition requiring assignment before closing, and you will be negotiating that under time pressure. Worse, a license from a founder to the company can be attacked as a related-party arrangement. Clean title inside the operating entity removes the issue entirely, and it is a standard line item on the checklists in investor due diligence.

Sale and licensing

Buyers prefer to acquire an entity that owns everything it operates on. A patent held personally means a separate assignment, a separate signature, and separate tax treatment on the proceeds. Valuation itself is unaffected by the holder, as explained in how to value a patent before you sell or license it, but deal mechanics are not.

Multiple founders

When two or three people invent together, personal ownership creates independent co-owners who can each license the technology to competitors. Assigning everything to a jointly owned entity converts the problem into a governance question you can solve with an operating agreement, which is where it belongs — see IP in a founders agreement.

When Personal Ownership Still Makes Sense

  • You have no entity yet and a disclosure deadline is closing. File the provisional in your own name today and assign later. A missed priority date is unrecoverable; an assignment executed three months late is routine.
  • The invention is outside the company's business. If your LLC sells irrigation controllers and you invent a bicycle mechanism, putting the bicycle patent in the same entity entangles two unrelated asset pools.
  • You plan to license rather than build. An independent inventor licensing to established manufacturers may prefer personal ownership plus a simple licensing entity, since the operating risk of a product business is absent.

Fees, Taxes, and the Details People Miss

USPTO fee discounts follow the applicant, not the inventor. Micro entity status cuts most fees by 75 percent, but the income cap and prior-filings limit apply to the entity that holds the application — assigning to a company with more than 500 employees or to any organization that fails the test moves you to undiscounted rates immediately. Check the criteria in USPTO micro entity status before you assign, because the difference on a single application can run well over $1,500 across filing, examination, issue, and maintenance.

On the tax side, a sale of a patent by an individual inventor can qualify for long-term capital gain treatment under a provision that does not apply the same way to corporate holders; royalty income is ordinary income either way. Assigning appreciated IP into an entity can itself be a taxable event. Involve a CPA before signing.

One more trap: if you invented while employed elsewhere, your employer may already own the invention regardless of which box you check on the USPTO form. Read employee IP rules before filing anything.

A Clean Sequence That Works

  1. Identify true inventors from lab notebooks and design files.
  2. Form the entity if you intend one to own the IP.
  3. File the application naming the inventors, with the entity as applicant.
  4. Execute and record the assignment from every inventor.
  5. Have every contractor and employee sign an invention assignment agreement covering future work.

Get the Structure Right Before the Filing Deadline
