A Confidential Information and Invention Assignment Agreement, usually shortened to CIAA, is a private contract that transfers ownership of the intellectual property you create on the job to your employer and restricts how you use the company’s proprietary information. Technology companies, startups, and creative firms hand it to you during onboarding, and it binds you from your start date through your last day, and often beyond. There is no government-issued template. Every company drafts its own, so the specific terms vary and are frequently negotiable before you sign.
What the Agreement Actually Covers
Most CIAAs are built from four core sections. Knowing what each one does is what lets you read the document with any real understanding.
- Confidential information. Defines what the company treats as proprietary: trade secrets, customer lists, product plans, source code, financial data, internal communications. You agree not to disclose or use any of it outside your job, during employment and after it ends.1U.S. Securities and Exchange Commission. Form of Confidential Information and Invention Assignment Agreement
- Invention assignment. Assigns to the company all inventions, original works, and improvements you conceive or develop during your employment that relate to the company’s business or use company resources. This is the clause that makes the company, not you, the owner of what you build on the clock.
- Prior inventions schedule, often labeled Exhibit A. Carves out intellectual property you owned before your start date so it stays yours. You fill in the schedule to formally exclude those items.
- Non-solicitation and non-disclosure. Restricts you from recruiting the company’s employees or contractors and from sharing confidential information after you leave. Some agreements bundle a non-compete here as well, though enforceability of non-competes varies sharply by state.
Clauses to Read Closely Before You Sign
CIAAs are presented as boilerplate, but the language varies from company to company, and you live with whatever you agree to. A few places tend to hide most of the risk.
Scope of the Assignment
Check whether the invention assignment covers only work related to the company’s business or sweeps in everything you create during the employment period. Overly broad clauses can try to claim side projects, personal apps, or open-source contributions you build on your own time with your own equipment. Several states make that kind of overreach unenforceable by statute, but catching it now is cheaper than litigating it later.
Definition of “Company”
Many CIAAs define the company to include parent organizations, subsidiaries, and affiliates. That broadens who can claim your work. If you are joining a startup that sits inside a larger corporate family, that single definition could assign your inventions to an entity you have never worked for.
Trailer Clauses After Termination
Look for a provision that extends the invention assignment for a period after you leave. Anything you invent within that window, commonly six to twelve months, could still belong to your former employer if it relates to work you did there. The shorter and more narrowly scoped this window, the better for your future career.
Filling Out the Prior Inventions Schedule
Exhibit A is the single most important part of the agreement for protecting what you already own. Everything listed stays yours. Everything you leave off risks being treated as company property down the road.
For each prior invention, include a descriptive title, an approximate date of creation, and a brief summary of what it does. If it has a patent number or copyright registration, add that identifier. You do not need to reveal implementation details or proprietary logic, just enough for the company to know the item exists and what it covers.2U.S. Securities and Exchange Commission. Form of Employee Proprietary Information and Inventions Agreement If disclosing a prior invention would violate a confidentiality agreement with a third party, most forms let you list only the name and the party that owns it.
Open-source contributions deserve special attention. If you maintain or contribute to open-source projects, list them with the project name, your role, and the approximate dates of involvement. An unlisted open-source project that later becomes relevant to the employer’s business is at serious risk of being treated as assigned property. Complete the schedule before signing, not after. Additions made later can raise questions about whether the work truly predated your employment.
If you have no prior inventions, you still need to address the section. Most forms require you to check a box or write a statement confirming that none exist.2U.S. Securities and Exchange Commission.

State Laws That May Already Protect Your Personal Projects
Even when a CIAA’s language is broad, several states have statutes that override assignment clauses for inventions you develop entirely on your own time using your own equipment, as long as those inventions do not relate to the employer’s business or result from work you performed for the employer.
California’s version is one of the most established. Under Labor Code Section 2870, any provision requiring you to assign an invention developed entirely on your own time without using the employer’s equipment, supplies, facilities, or trade secret information is unenforceable, unless the invention relates to the employer’s business or its anticipated research, or results from work you did for the employer.3California Legislative Information. California Labor Code Section 2870 The statute also requires employers to give you written notice of the protection when the agreement is signed.
New York adopted nearly identical language under Labor Law Section 203-f, making assignment provisions unenforceable for inventions developed entirely on your own time and resources that fall outside the employer’s business.4New York State Senate. NY State Senate Bill 2023-S5640 Illinois has had a similar statute since 1984 under the Employee Patent Act, and adds an explicit requirement that the employer provide written notification at signing explaining the clause does not cover inventions developed on your own time without company resources.5FindLaw. Illinois Statutes Chapter 765 Property 1060/2
Delaware, Minnesota, Washington, and North Carolina have comparable protections. The exact boundaries differ. Some place the burden of proof on the employee, others are silent, so check the statute in your state before assuming a side project is safe. Whatever state you work in, the safer practice is to build personal projects on personal equipment, during personal time, without touching work email or cloud accounts, and to document the timeline so you can prove the work predates or falls outside your employment.
Signing the Agreement
You can sign a CIAA on paper or electronically. Under the federal E-SIGN Act, a contract cannot be denied legal effect solely because an electronic signature was used to form it.6Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity Both you and a company representative need to sign for the agreement to take effect. Your signature alone does not create a binding contract.
Once both sides have signed, ask for a fully executed copy for your own records. A digital scan is fine, but make sure you actually receive it. Store your copy somewhere secure and separate from company systems, on a personal cloud account or in a safe at home. If a dispute arises years later, the person holding the signed agreement has a significant advantage over the person who has to ask a former employer for one.
If You Are Asked to Sign After You Are Already Employed
A contract needs consideration, something of value from both sides, to be enforceable. For a new hire, the job itself is the consideration: the company hires you, and you sign the CIAA. That arrangement is straightforward and rarely challenged.
Things get murkier when you are already employed and the company asks you to sign a CIAA for the first time, or a revised version. Some courts have held that continued at-will employment is enough consideration to support the agreement. In others the question is unsettled, and employers reduce their risk by offering something extra: a bonus, a raise, additional stock options, extra paid time off. If your employer hands you a CIAA months into the job without offering anything in return, flag it. The agreement’s enforceability could be weaker than either side assumes.
What Still Binds You After You Leave
Signing a CIAA creates commitments that survive your departure. Confidentiality and non-disclosure clauses typically remain in effect indefinitely or for a stated number of years, meaning you cannot share trade secrets or proprietary information with a new employer or use them to build a competing product.
Most agreements also require you to return all company property when the relationship ends. That covers the obvious items, laptops, access badges, corporate credit cards, but also documents, files, notes, databases, and any copies stored on personal devices. Some companies set a specific deadline, commonly within five business days of your last day, and tie the return of property to the release of severance payments or final paychecks.
Digital access matters as much as physical property. Delete company data from personal devices, revoke your access to company cloud accounts, and stop using work credentials for third-party services. Keeping a copy of a client list or a code repository “just in case” is exactly the kind of act that triggers trade-secret claims. The confidentiality obligation does not expire because you changed jobs, and enforcement usually gets more aggressive once you land at a competitor.
If the agreement contains a trailer clause, watch its duration and scope. During that window, any invention you create that relates to work you did at the former company could still be claimed by them. Document the development timeline and funding source of any new project you start after leaving, so you can show it falls outside the trailer clause if challenged.
