You built something valuable. Now someone might steal it. Here is what you can do. To protect a software algorithm, you have four main tools: patents, trade secrets, copyright, and non-disclosure agreements (NDAs). Most developers and businesses use a combination of these. The right strategy depends on your algorithm’s uniqueness, how public it needs to be, and your long-term business goals.
Let’s walk through each option so you can make a smart decision.
What Makes an Algorithm Worth Protecting?
Before choosing a strategy, ask yourself a few questions. Does your algorithm solve a problem in a new way? Does it give your business a competitive edge? Could a competitor copy it if they saw your code?
If you answered yes to any of those, protection is worth pursuing. Our intellectual property attorneys work with inventors and businesses every day who face this exact question.
Option 1: Apply for a Patent
A utility patent is one of the strongest ways to protect a software algorithm. It gives you the exclusive right to your invention for up to 20 years. During that time, competitors cannot make, use, import, or sell your invention without permission.
However, patents come with tradeoffs. The application process is detailed and takes time. You also have to publicly disclose your algorithm as part of the process. Once published, competitors can see how it works.
That tradeoff is significant. Some businesses decide a patent is not worth the disclosure. Others decide the exclusivity is worth it.
To get a patent on an algorithm, it generally must be tied to a specific process or machine. Courts have ruled that abstract ideas alone are not patentable under 35 U.S.C. § 101. Your attorney can help you frame the application correctly to meet this standard.

Option 2: Protect It as a Trade Secret
A trade secret is another option to protect a software algorithm. It protects your algorithm indefinitely, as long as you keep it confidential. This is often the smartest choice for algorithms that power your product behind the scenes.
Think of how Google keeps its search algorithm private. No patent. No public disclosure. Just strict internal controls. The formula works because nobody outside the company knows how it works.
To qualify as a trade secret, you need to take active steps to keep the information confidential. That includes:
- Restricting access to only those who need it
- Using strong security measures for your codebase
- Having employees and contractors sign NDAs
- Documenting your efforts to maintain secrecy
If someone steals your trade secret, you can pursue legal action under the Defend Trade Secrets Act and applicable state laws.
The downside? If someone independently develops the same algorithm, you have no legal claim against them. Trade secret protection only covers misappropriation, not independent discovery.
Option 3: Use Copyright Registration
Copyright automatically protects original code the moment you write it. You do not need to register. However, registering your copyright with the U.S. Copyright Office strengthens your legal position significantly. It creates a public record and allows you to seek statutory damages if someone infringes your work.
Copyright protects the expression of your algorithm, meaning the actual code. It does not protect the underlying idea or logic. So if a competitor rewrites your algorithm in a different language or structure, copyright alone may not stop them.
Still, copyright is an easy, affordable layer of protection to add. It works well alongside patents and trade secrets.
Option 4: Use NDAs and Contracts
Non-disclosure agreements are your first line of defense in any collaboration. Before sharing your algorithm with a developer, partner, investor, or vendor, get an NDA signed.
NDAs are not just for big corporations. A well-drafted agreement protects you the moment you share your idea with someone outside your organization.
You should also include strong IP ownership clauses in your employment and contractor agreements. You want to make sure the algorithm belongs to your business, not the person who coded it.
Contracts will not stop every bad actor, but they create legal recourse when something goes wrong.
Which Protection Strategy Is Right for You?
Here is a simple breakdown to help you think through your options:
Choose a patent if:
- Your algorithm is novel and non-obvious
- You want to license the technology or attract investors
- You are comfortable with public disclosure
Choose a trade secret if:
- Secrecy is practical and sustainable for your business
- You want long-term protection without an expiration date
- Public disclosure would harm your competitive advantage
Use copyright if:
- You want a low-cost baseline layer of protection
- You want a public record of ownership
Use NDAs and contracts always. There is no situation where these are optional if you share your algorithm with anyone outside your company.
Most businesses benefit from layering multiple strategies together. Our team can help you build a protection plan that fits your specific situation.
Do Not Wait to Protect a Software Algorithm
Timing matters in intellectual property. If you publicly disclose your algorithm before filing a patent application, you may lose your right to patent protection in certain countries. The U.S. gives inventors a 12-month grace period after public disclosure, but other countries do not.
The sooner you act, the more options you have. Contact our team to schedule a consultation before your window closes.

Frequently Asked Questions About Protecting a Software Algorithm.
Can you patent a software algorithm?
Yes, you can patent a software algorithm in many cases, but there are limits. The algorithm must be tied to a specific technical process or machine. Courts have consistently held that abstract mathematical formulas alone do not qualify for patent protection. Working with a registered patent attorney helps you frame your application in a way that meets USPTO requirements and avoids rejection.
How long does trade secret protection last for an algorithm?
Trade secret protection lasts as long as the information stays confidential. Unlike patents, there is no expiration date. However, protection ends the moment the secret becomes public, whether through a breach, a leak, or independent discovery by someone else. That is why maintaining strong internal security practices and NDAs is critical.
Does copyright protect my algorithm?
Copyright protects the specific code you write, not the underlying idea or logic behind the algorithm. If someone copies your source code directly, copyright gives you strong legal recourse. However, a competitor who recreates the same functionality with different code may not infringe your copyright. Copyright works best when combined with other protections.
What is the difference between a patent and a trade secret for software?
A patent gives you a public, time-limited monopoly (typically 20 years) on your invention. You must disclose how it works, but you gain the exclusive right to use and license it. A trade secret keeps the algorithm private with no expiration, but offers no protection if someone independently develops the same thing. The best choice depends on whether secrecy or exclusivity serves your business better.
