You cannot legally own a business idea on its own. To protect a business idea, protect what is built around it. Keep valuable methods and data secret, file a provisional patent for a real invention, and register the name as a trademark. Then get every contributor's work assigned to the company in writing.
This guide shows which tool covers which part of your business, what each one costs, and the two gaps founders most often leave open. It explains the main tools and is not legal advice.

U.S. copyright law does not protect "any idea, procedure, process, system, method of operation, concept, principle, or discovery."
A trade secret stays protected only while its owner takes "reasonable measures" to keep it secret.
A provisional patent application costs $65, $130 or $325 to file, depending on entity size, under the USPTO's 2025 fee schedule.
A provisional application lasts 12 months, and that period cannot be extended.
A trademark application costs $350 per class of goods or services.
Have every founder, employee and freelancer assign their work to the company before they start.
No, not the idea itself. U.S. law protects specific things built around an idea, not the concept. A business concept in a pitch deck belongs to nobody. What you can own is narrower: information you keep secret, an invention you file for, a name you register and material you write down. That is where protection starts.
Founders often hesitate to describe an idea to an adviser or investor for fear it will be taken. The fear is mostly misplaced. Section 102(b) of the Copyright Act says copyright protection does not extend to "any idea, procedure, process, system, method of operation, concept, principle, or discovery." That holds however the idea is described.
You cannot own an idea. You can own everything that makes it hard to copy.
Five parts of a business can be protected, and each needs a different tool. Together they form a Protection Stack: secrecy, invention, name, expression and contracts. No single layer protects a business on its own. A founder who files a patent but ignores who owns a contractor's code has left the foundation open.
Secrecy = information that has value because others do not know it.
Invention = a new product or process that can be patented.
Name = the brand customers use to find you.
Expression = written and designed material, from code to copy.
Contracts = agreements that bind the people who see or build the rest.
Quick test: list the three things a competitor would most want from your business. For each one, name the layer that protects it today. Any item without a layer is the place to start.
Three tools cover most early-stage needs. Keep the valuable parts secret, which costs almost nothing. File a provisional patent if there is a real invention, which secures a filing date for a small fee. Register the business name as a trademark. Each tool protects a different layer, and each is cheapest when used early.
Customer lists, pricing models, supplier terms and methods can all be trade secrets, and protecting them costs little. Federal law defines a trade secret as information whose owner "has taken reasonable measures to keep such information secret." It must also derive "independent economic value" from not being generally known. So the protection depends on how the owner behaves.
What to do: limit access, mark documents confidential, use written agreements.
Why it works: no registration, no fee, and no expiry while secrecy lasts.
Best for: processes, data and know-how that cannot be reverse-engineered.
Share the business model openly and keep the mechanics need-to-know. Record that line in your risk assessment.
If the idea includes a genuine invention, a provisional patent application secures an early filing date at low cost. The USPTO fee schedule, effective January 2025, sets the filing fee at $65 for micro entities, $130 for small entities and $325 for others.
Provisional applications are "not examined on their merits." They need no formal patent claim, and they let you use the term "patent pending." The 12-month period "cannot be extended."
What to do: file before you disclose the invention publicly, then decide within the year.
Why it works: it buys time to test demand before paying for a full patent.
Best for: physical products, devices and new technical processes.
A provisional application cannot become a patent unless a full application follows within the year. Put that deadline in your plan, next to the startup costs it will trigger.
A business name is often the first thing copied and the cheapest to protect. Under the same USPTO schedule, an electronic trademark application costs $350 per class of goods or services.
Trademark filing fee = $350 x Number of classes
Illustrative example: a micro-entity founder files one provisional patent (65)andatrademarkintwoclasses(700). That is $765 in government filing fees before any attorney fees.
What to do: search existing registrations, then file in the classes you will actually use.
Why it works: it stops others registering a confusingly similar name.
Best for: any business planning to advertise or grow beyond one location.
Run a trademark search and check the name against the rivals in your competitive analysis before you file.
Most founders who lose control of an idea lose it through gaps they created themselves. Two are common. Some refuse to talk without a non-disclosure agreement and miss the meetings they need. Others let co-founders or freelancers build core work with no written agreement on who owns it. Both gaps are cheap to close early and expensive to fix later.
The founder insists on a non-disclosure agreement (NDA) before every conversation. Many investors decline. The founder then either walks away from useful meetings or shares anyway, with no agreement. The fix: separate what you share by layer. Describe the problem, the market and the business model freely, because none of it is protectable. Keep specific methods, data and code for parties who have signed, and only when the relationship needs them.
A co-founder, early employee or freelancer builds part of the product without a written agreement assigning the work to the company. Years later, at a funding round or sale, nobody can show the business owns its own core asset. The fix: have everyone who contributes sign an assignment of intellectual property to the company before work starts, founders included. The same applies when you partner with other businesses: agree in writing who owns what you create together.
What you want to protect | Tool | Typical cost | Who must act |
Methods, data, pricing | Trade secret practices | Internal time | Founder and every employee |
A new invention | Provisional, then full patent | From $65 to start | Founder with a patent attorney |
The business name | Trademark registration | $350 per class | Founder before launch |
Code, content, designs | Copyright and assignments | Minimal | Every contributor, in writing |
Shared information | NDA or confidentiality terms | Minimal | Both parties, before disclosure |
Knowing how to protect a business idea is less about secrecy than about structure. The concept cannot be owned, and treating it as if it could makes founders hide from the people they most need. The parts that can be owned are protected by small, early, written steps. They cost little at the start and a great deal to repair later.
The order is simple. Decide what is truly secret and restrict it. File a provisional application if there is a real invention. Register the name. Put every contributor's work under the company's ownership in writing. Then speak freely about the rest. Set the whole arrangement out in your plan. An investor can then see the company owns what it says it does, starting from the business idea itself.
PrometAI's Entrepreneur Journey includes an intellectual property protection tool and the trademark search above, so you can map your IP layers before you file. For an invention, work with a patent attorney.
