You might assume that if you pay someone to build something for your startup, the company automatically owns it. That is often a dangerous assumption. In the world of intellectual property, the creator is usually the default owner unless a specific legal transfer takes place.
An Assignment of Inventions agreement is the legal mechanism that executes this transfer. It is a contract between the company and an individual. It states that any intellectual property created during the course of employment or engagement belongs to the company, not the individual who created it.
This document is the bedrock of your company’s value. Without it, you might be building a house on land you do not own.
The Core Mechanism
#The primary function of this agreement is to strip the individual of rights to their creation and vest them in the corporate entity. This covers a wide spectrum of outputs.
- Source code and software architecture
- Patents and patentable ideas
- Trade secrets and proprietary processes
- Designs and creative works
When a developer writes code for your app, they technically hold the copyright the moment it is written. The Assignment of Inventions moves that copyright from the developer to the startup. This creates a clean chain of title.
Why Investors Require It
#
When you approach venture capitalists or angel investors, they will perform due diligence. One of the first things their lawyers look for is the intellectual property assignment.
They need to know the company actually owns the asset they are investing in. If a co-founder leaves the company after six months and never signed an assignment agreement, they could theoretically claim ownership of the core technology. This creates a legal toxicity that makes the company uninvestable.
Assignment vs. Work Made For Hire
#Founders often confuse “Assignment of Inventions” with “Work Made for Hire.” They are related but distinct concepts.
Work Made for Hire is a copyright term. It applies automatically to employees for certain types of work, but it has significant limitations regarding independent contractors. Furthermore, it generally does not cover patent rights.
An Assignment of Inventions agreement is broader. It explicitly transfers patent rights, trade secrets, and other forms of IP that fall outside the scope of copyright. Relying solely on work-for-hire doctrine leaves massive gaps in your protection.
Limitations and State Laws
#It is important to understand what this agreement cannot do. It generally cannot claim ownership of things an employee creates entirely on their own time, without using company equipment, and that do not relate to the company’s business.
States like California have specific labor codes that limit the reach of these agreements. This raises important questions for the founder to consider.
Where does the line blur between a hobby and a competing product? If an employee has a side project, have you clearly documented it as a “prior invention” to avoid future disputes?
Securing these agreements from every single person who touches your product—including yourself—is not optional. It is the only way to ensure the business retains the value it creates.
