Intellectual property is a startup’s core asset. The most critical mistake is founders failing to assign their pre-incorporation IP to the new company. Securing IP requires signed assignment agreements from all founders, employees (via CIIAAs), and contractors. Understanding the tactical differences between trademarks, copyrights, patents, and trade secrets allows you to build a defensible business and pass investor due diligence.
Key takeaways
- Force every founder, employee, and contractor to sign an IP assignment agreement before they write a single line of code.
- Audit your codebase for "viral" open-source licenses like GPL or AGPL that can compromise your proprietary code.
- Don't file patents reactively. Most software startups should focus on product, not patents, in the first year.
- Run a trademark search *before* you commit to a brand name to avoid a painful and expensive rebrand.
- Create an IP register to track who has contributed what and confirm they have signed the correct agreements.
- Clean IP is not a "nice to have"; it is a prerequisite for any serious seed or Series A investment.
Let’s cut the fluff. For a tech startup, your company isn’t a mission or a product—it’s a collection of intellectual property. Your code, your brand, your secrets. That’s the entire game. Getting IP wrong at the start is a company-killer. It will blow up investor diligence, block an acquisition, or let a competitor eat your lunch.
This is not a task you delegate to your lawyers and forget. Your IP strategy is your business strategy. Protecting your assets is as important as building them. Here are the unforgivable mistakes and how you can avoid them.
You and your co-founders have been hacking away for months. You’ve built a prototype, designed a logo, bought a domain. Then you form your Delaware C-Corp. Here’s the terrifying truth: the new corporation owns absolutely none of it. You, the individual, still own the IP you created.
If you don't formally transfer this work to the company, your startup is an empty shell. When a VC’s lawyer finds this in diligence—and they always do—they will halt the investment. Why would they fund a company that doesn’t own its own product?
The Fix: The Founder IP Assignment. As part of your incorporation, every single founder must sign an Intellectual Property Assignment Agreement. This document formally transfers all relevant pre-incorporation assets (code, designs, domains, inventions, even social media handles) from the individuals to the company. This is non-negotiable. If your lawyer doesn’t make this a mandatory step, find a new lawyer.
Once you’ve solved the founder IP issue, you need to control the flow of IP from everyone who touches the company. Don’t trust handshakes. Don’t rely on assumptions.
Every employee, from day one, must sign a Confidential Information and Invention Assignment Agreement (CIIAA) . This is the core of your IP protection strategy. It has two jobs:
It obligates the employee to keep your secrets (trade secrets) confidential.
It automatically assigns any IP they create related to their job to the company.

Frequently asked questions
- Can I use a service like Stripe Atlas or Clerky for my incorporation and IP?
- Yes, these services are excellent for establishing a standard setup, including the critical founder IP assignment agreements. Think of them as a strong foundation, but you will still need to manage ongoing IP hygiene with employees and contractors as you grow.
- What happens to IP if a co-founder leaves the company?
- If they signed an IP Assignment Agreement, the company owns all the work they did. Their departure is then an equity and HR issue, not an IP one, which is exactly how it should be. This prevents a departing founder from claiming ownership of the core product.
- How much should I budget for legal IP work in my first year?
- For a standard software startup, budget $3,000-$7,000 for an incorporation package that includes proper IP assignments. A trademark search and registration will add $1,500-$3,000. A provisional patent, if necessary, can run $3,000-$5,000. Don't cut corners here.
- Do I really need an expensive lawyer for this?
- Yes. Using a reputable startup law firm isn't just about documents; it's about gaining their strategic advice and pattern recognition from hundreds of deals. Cutting corners on legal is one of the most pound-foolish decisions a founder can make.
