You spent the weekend with Claude Code, Cursor, or Replit. Maybe it was three weekends. You iterated, tested, refined, and suddenly you’re looking at something real, a working app, a SaaS prototype, a tool that does something nobody else’s does quite the same way. The obvious next thought: how do I protect this before somebody with the same AI tools builds the same thing next week?
Welcome to the new reality of software development. And welcome to the question every serious vibe coder, indie hacker, and solo founder is now asking.
The Problem: When Everyone Has AI, Ideas Are the Only Moat Left
A year ago, building a polished web app took a team, a budget, and a timeline measured in months. Today, a non-technical founder can ship a functioning MVP over a long weekend. Y Combinator has reported that roughly a quarter of its recent startup cohorts are shipping nearly all-AI-generated codebases. Microsoft’s CEO has said that AI now writes about 30% of the company’s new code. Gartner projects that within a few years, 40% of new business software will be generated from natural-language prompts.
That’s a revolution for builders. It’s also a crisis for anyone who thought their code was their moat.
Here’s the uncomfortable truth nobody is telling you: your AI-generated code may not be protectable by copyright.In Thaler v. Perlmutter, the D.C. Circuit confirmed that U.S. copyright law requires human authorship. The U.S. Copyright Office has held, in its post-2023 guidance, that AI outputs lacking sufficient human creative control are not eligible for registration. If your competitor prompts the same model with a similar description, they can likely get similar code. That’s not a moat. That’s a puddle.
So what actually protects the idea behind what you built? The method, the workflow, the technical approach that makes your app work the way it does?
A patent. Specifically, and as a first step, a provisional patent application.
What a Provisional Patent Actually Does
A provisional patent application is filed with the United States Patent and Trademark Office (USPTO) and establishes an official priority date for whatever you’ve disclosed and enabled in the specification. From the moment it’s on file, you can legally and truthfully say your invention is “patent pending.” You get 12 months to file a full non-provisional application claiming that priority date. During that year, you can pitch investors, publish a landing page, launch publicly, or keep iterating, without surrendering your place in line at the Patent Office.
A few things to be clear about, because we’re a patent law firm and we refuse to oversell:
- A provisional does not protect your source code as code. That’s a copyright question, and as noted above, it’s a complicated one for AI-generated work.
- A provisional does not protect the look of your UI as ornamental design. That’s a design patent, which is a different animal.
- A provisional does protect the underlying method, system, or process that makes your software novel, for example a specific way of processing data, a new retrieval-augmented generation workflow, a unique fraud-detection loop, a novel approach to personalization, or a technical solution to a specific problem that wasn’t obvious before.
That’s where the real value of most modern software lives anyway. And it’s what a well-drafted provisional captures.
Why “Just Don’t Bother” Is the Wrong Answer
A common argument goes like this: “Software is hard to patent, eligibility rules are strict, so don’t waste the money.” That argument is outdated, and in the age of vibe coding, it’s actively dangerous advice.
Software patents absolutely are granted every day. The USPTO grants them when the application frames a real technical problem and a real technical solution, and when the claims are drafted by someone who actually knows how to navigate Section 101 subject-matter eligibility. That’s not a DIY job. That’s the entire reason patent attorneys exist.
And here’s the strategic piece: even if you never pursue the full non-provisional, having a provisional on file does three important things for your business:
- It locks in your priority date against anyone who files after you, including a competitor using the same AI tools to build a similar product.
- It gives you “patent pending” status, which carries real weight with investors, potential acquirers, and enterprise customers evaluating whether to bet on you.
- It buys you 12 months to figure out whether the idea has traction, whether the market responds, and whether it’s worth the investment of a full non-provisional application. If the answer is no, you walk away having spent a fraction of the cost of a full filing.
The Cost Reality (And Why This Is the Time to Act)
Industry data puts typical attorney fees for a software provisional patent application at roughly $6,000 to $8,000 at most firms, with complex software applications running up to $10,000. Full non-provisional software patents typically cost $8,000 to $12,000 to draft and file, and total costs through prosecution to issuance commonly run $15,000 to $25,000or more according to the American Intellectual Property Law Association’s biannual economic survey.
Those numbers scare off exactly the people who would benefit most: solo founders, indie hackers, small teams shipping with AI tools. That’s not acceptable to us.
Flat-Rate Software Provisional Patents at Underwood & Associates
We’ve serving inventors and companies nationwide and internationally since 2007. We practice exclusively in patents. That’s all we do.
Here’s what that means for you:
- Flat-rate pricing, typically $3,500 to $5,500 for a well-drafted software provisional patent application, with the exact quote depending on the complexity of your invention. No hourly billing surprises. No padded estimates. You know the number before we start.
- Fast turnaround. We understand that when you’re moving at AI speed, a three-month patent drafting cycle is a non-starter. We build around your timeline.
- Deep expertise in software and AI inventions. We draft patent applications for machine learning workflows, AI-powered platforms, novel software architectures, and the full range of computer-implemented inventions. We understand both the technology and the case law that governs its patentability.
- A clear path forward. If you decide to convert to a non-provisional within your 12-month window, we offer flat-rate pricing on that too. If you want to file internationally via the Patent Cooperation Treaty (PCT), we’ve been handling PCT practice for nearly two decades.
What You Need to Bring Us
To draft a strong provisional, we need you to tell us honestly what your invention does and how it does it. Ideally:
- A plain-language description of the problem you’re solving
- A technical explanation of how your app solves it (the method, the workflow, the architecture)
- Any flowcharts, diagrams, screenshots, or architecture sketches you already have
- A candid assessment of what, to your knowledge, is genuinely new about your approach
If you don’t have all of this polished, that’s fine. Part of what we do is draw it out of you in a focused working session, then translate it into a specification that will stand up if and when it’s examined.
The Bottom Line
If you’ve built something real with AI tools and you think you have something, the worst thing you can do is wait. Every day you don’t file is a day somebody else can file first. Under the America Invents Act, the U.S. patent system is first-inventor-to-file. Priority belongs to whoever gets to the Patent Office first, not whoever had the idea first.
A provisional patent application, filed quickly and drafted well, is the single most cost-effective move you can make to protect what you’ve built. It’s a few thousand dollars. It buys you a year, a priority date, and the right to say “patent pending” to every investor, customer, and competitor who asks.
That’s a moat worth having.
Ready to File?
If you’re an inventor, founder, or solo builder and you want to know whether your AI-built app, SaaS product, or software innovation is worth patenting, we offer a free initial consultation. We’ll give you a straight answer about whether your invention has a patentable core, what the scope of protection might look like, and exactly what it will cost to file.
