Filing a patent for your AI invention doesn’t have to be complicated. If you’re a developer or startup founder in the United States wondering how to protect your AI innovation, this simple guide walks you through the basics.
Whether you’re building a machine learning tool, an AI app, or an automation system, understanding the patent process helps you make smart decisions about protecting your work.
Should You Patent Your AI Innovation?
Not every AI project needs a patent. Before spending time and money on filing, ask yourself: does my technical innovation give me a competitive edge that competitors could copy?
Patents work best when you’ve created something technically unique. For example, a new way to train AI models faster, a specific method for processing data more efficiently, or a novel approach to solving a particular technical problem.
If your advantage comes from your data, customer relationships, or how fast you execute, you might not need a patent at all. Many successful AI companies never file patents and do just fine.
What AI Inventions Can You Patent?
The US Patent and Trademark Office has clear rules about AI patents.
You can patent: Specific technical solutions. Like a particular method that makes AI models smaller and faster, a unique system that combines different AI approaches to reduce costs, or a concrete technique that improves accuracy in a measurable way.
You cannot patent: Broad ideas or abstract concepts. You can’t patent “using AI for predictions” or “a machine learning system for business.” These are too general.
The key is specificity. Your invention must describe exactly how something works technically, not just what result it achieves.
One important rule for 2026: only humans can be listed as inventors. AI tools can help you develop your invention, but the patent application must list the people who created the inventive ideas.
The Two Main Ways to File
The US patent system offers two filing paths, and most beginners start with the simpler option first.
Provisional Patent Application
This is like a placeholder that costs less and buys you time. You file a description of your invention, pay a small fee (around $400-$800 for small companies), and get a filing date proving you invented it by that date.
A provisional application gives you 12 months to test your product, find customers, or raise funding before deciding whether to file the complete application. Many founders use this to protect their idea while figuring out if it’s worth the full investment.
Non-Provisional Patent Application
This is the full, formal application that gets examined by the USPTO. It requires detailed technical descriptions, formal legal claims, and proper documentation.
Most people hire a patent attorney for this step because it’s complex and mistakes can hurt your chances of approval.
Simple 5-Step Filing Process
Here’s how the patent filing process actually works:
Step 1: Document Your Invention
Write down exactly what you invented. Include what problem it solves, how it works step-by-step, why it’s different from existing solutions, and what specific benefits it provides.
For AI inventions, add technical details like system diagrams, how data flows through your system, and specific algorithms or methods you use.
Keep dated records of your work—code commits, design notes, test results. These prove when you invented each part.
Step 2: Search Existing Patents
Before filing, search for similar patents using free tools like Google Patents or the USPTO database. Look for inventions similar to yours and understand what’s already been patented.
This step helps you avoid wasting money on inventions that aren’t actually new and shows you how to describe your invention as different from existing patents.
Step 3: Prepare Your Application
For a provisional application, write a clear description with enough technical detail that someone skilled in AI could understand and recreate your invention.
Include diagrams, flowcharts, and concrete examples. The more specific details you provide, the better your protection.
You don’t need formal legal claims in a provisional application, but describe what parts of your invention you think are new and important.
Step 4: File with the USPTO
File online through the USPTO website. You’ll upload your documents, pay the filing fee, and receive a confirmation with your filing date.
After filing, you can use “Patent Pending” on your product or website. This tells people you’ve applied for patent protection.
Step 5: Decide on Full Application
During the 12 months after filing your provisional application, decide whether to file the full non-provisional application. This is when most people hire a patent attorney.
The attorney helps write formal claims, responds to USPTO questions, and handles the examination process that takes 2-4 years.
What It Actually Costs
Budget matters for startups, so here are realistic costs for 2026:
Provisional application: $400-$800 USPTO fee if you’re a small company. Add $2,000-$5,000 if you hire an attorney to help, though many founders file this themselves.
Non-provisional application: $800-$1,600 USPTO fee, plus $10,000-$20,000 in attorney fees for AI inventions. Total cost from start to getting your patent granted typically runs $20,000-$40,000.
Maintenance fees: After your patent is granted, you pay fees at 3.5, 7.5, and 11.5 years to keep it active. These total about $7,500 for small companies over the patent’s 20-year life.
Many startups file provisional applications themselves to save money, then decide later whether the full patent is worth the investment.
Common Mistakes Beginners Make
Avoid these mistakes that trip up first-time filers:
Filing too late: If you publicly share your invention—in a blog post, presentation, or product launch—you have only 12 months to file or you lose patent rights forever. Many developers accidentally destroy their patent rights by publishing code or giving talks before filing.
Being too vague: Saying “an AI system that makes better predictions” isn’t enough. You need specific technical details about how your system works and what makes it different.
Skipping the patent search: Filing without checking for similar patents first usually leads to rejection. Search first, then file.
Claiming too much: Trying to patent every possible variation of your idea doesn’t work. Focus on specific, concrete innovations that are genuinely new.
When Patents Don’t Make Sense
Sometimes skipping patents is the smarter choice. Consider not filing if:
- Your competitive advantage is your data, not your algorithms
- Speed to market matters more than legal protection
- Your business depends on customer relationships, not technology barriers
- You’re bootstrapped and every dollar needs to go toward product development
Many successful AI startups never file patents. They protect their innovations through speed, trade secrets, or building products where AI is just one piece of a larger system.
What Happens After Filing
After you file a non-provisional application, a USPTO examiner reviews it. This takes 6-12 months to start and often 2-4 years total to complete.
The examiner will usually send at least one “office action” pointing out issues or asking questions. You respond, often revising your claims. This back-and-forth is normal.
If approved, you get a patent that lasts 20 years from your filing date. You can prevent others from using your invention in the United States during this time.
Should You Hire a Patent Attorney?
For provisional applications, many founders file themselves to save money. The forms are straightforward if you can document technical systems clearly.
For non-provisional applications, hiring a patent attorney is usually worth it. AI patent applications are technical and complex. Attorneys know how to write claims that get approved and can respond effectively to USPTO objections.
A good middle path: file a provisional yourself to establish your filing date and save money, then hire an attorney during that 12-month window to prepare the full application.
Next Steps for Your AI Patent
If you’re serious about filing a patent for your AI invention, start by documenting exactly what you’ve created and how it works. Search existing patents to understand what’s already out there. Then decide whether a provisional application makes sense for your situation.

Remember: patents are just one tool for protecting innovation. The best choice depends on your specific situation, business model, and resources. Focus on building a great product first, and use patents strategically when they actually support your business goals.
