What Is an IP Assignment Agreement?

Copy section link

An IP assignment agreement is a document that officially transfers ownership of intellectual property (IP) from one person or company to another. Intellectual property includes things like inventions, designs, software, logos, names, and written work — anything that someone creates with their mind. This agreement makes it clear who the new owner is, so there's no confusion or legal trouble later.

When Should I File an IP Assignment Agreement?

You should use an intellectual property assignment agreement when ownership of creative work or inventions needs to change hands. In particular, it may be helpful when you:

A business that owns copyrights, trademarks, or patents is sold;
A freelancer transfers their IP to a company that hired them;
An employee moves IP ownership to their employer. In this case, a special form of the document, an employee ip assignment agreement, is needed;
One company branch assigns rights to another;
A start-up founder leaves, and the business wants to keep the rights to ideas they helped create;
You want someone else to own your registered trademark or patent.

How to Set Up an IP Assignment Agreement

Drafting this document can be simple if you use an IP assignment agreement template and follow these steps:

Write the full name and contact information of the person giving away the IP (the Assignor). Do the same for the person receiving the IP (the Assignee). If you use an employee IP assignment agreement template, add the name of the company to which the intellectual rights are transferred.
Explain what type of intellectual property is being assigned. You might include a software name, patent number, or a short description of the work or design.
Mention whether the assignment is "full" (the Assignee gets complete ownership) or "partial" (the Assignee gets only part of the rights).
State if the Assignee is paying the Assignor and how much. If there's no payment involved, you can say the IP is being transferred as a gift or for another agreed reason.
Choose a date when the transfer becomes official.
Write down which state's laws will apply if ever a disagreement comes up. Usually, this is the state where one of the parties lives or works.
Both the Assignor and the Assignee must sign and date the filled-out intellectual property assignment agreement template.

Always keep a signed copy of the agreement in a safe place.

If you're unsure about what rights to transfer or dealing with a valuable idea, ask a legal professional before you sign anything.
