Businesses that never thought of themselves as technology companies are suddenly building technology. A marketing agency may create an AI workflow that drafts and routes client campaigns, a medical practice may build an intake-and-triage automation on top of an LLM and an accounting firm may create a custom tool that turns raw financials into client-ready reports.
LumaLex Law is doing this too. We are investing real time, money, and engineering resources into proprietary technology that helps our firm operate better. But as more companies build internal AI tools, a legal question is becoming harder to ignore: when the employee, contractor, consultant, or agency that built the tool leaves, who actually owns it?
Many business owners assume the answer is obvious…If the company paid for the work, the company must own it, but that assumption can be wrong. In the AI era, getting ownership wrong can create serious problems when someone leaves, when a dispute arises, or when the company raises capital, gets acquired, or tries to license what it built. This is why a proprietary rights agreement, sometimes called a Proprietary Information and Inventions Assignment Agreement, IP assignment agreement, or confidentiality and proprietary rights agreement, matters.
The Default Rules May Not Protect the Business
The default legal rules do not always give a company the clean ownership it assumes it has and the answer often depends on who created the work, what type of work it is, and whether the company had the right written agreement in place. For employees, copyright ownership is usually the simplest part. Work created by an employee within the scope of their job is generally treated as “work made for hire,” which means the employer owns the copyright by default. But copyright is only one part of the analysis.
Patentable inventions are different. Without a written agreement, an invention generally belongs to the individual who created it, not automatically to the employer, even if it was created on company time or using company resources. Courts may sometimes give the employer limited “shop rights” or apply a “hired to invent” theory, but those arguments are fact-specific and unpredictable. They are not a clean ownership strategy.
The biggest trap is often contractors and consultants. When an independent contractor builds software or custom technology, the work-made-for-hire doctrine usually does not apply in the same way. Without a signed assignment, the outside developer may own the copyright in the tool the company paid them to build. The company may have a license to use it, but not full ownership, not the unrestricted right to modify it, and not the clean title needed to sell the company or license the technology to others.
A proprietary rights agreement fixes that problem by putting ownership in writing before there is a dispute.
AI Did Not Create the Ownership Problem. It Made It Common.
For years, invention assignment and proprietary rights agreements were mostly associated with software companies, R&D teams, and businesses that clearly viewed themselves as technology companies. AI changed that.
LLMs have turned employees across departments into builders. A customer-service lead can create automations. An operations manager can design prompt libraries and internal agents. An associate can build document-generation tools. Valuable technology is now being created by people whose job descriptions may never have mentioned software, invention, or product development. That is where many companies are exposed. The business may be building valuable internal technology without realizing it has not secured ownership of the assets behind it.
AI also creates a newer ownership issue. The U.S. Copyright Office has taken the position that purely AI-generated material, without meaningful human authorship, is not protectable by copyright. That means the raw AI output may sit in a gray area, but the most valuable parts of the system are often not just the raw output. The architecture, code written around the model, prompt engineering, workflows, fine-tuning data, configurations, human curation, and editing may be protectable as copyrightable works, trade secrets, or both.Those are the assets a proprietary rights agreement is designed to capture for the company.
Why Confidentiality Matters More in AI Workflows
AI tools are not only about ownership. They also raise confidentiality and trade-secret concerns.
Prompts, system designs, automation playbooks, workflows, and internal agent structures may become competitive advantages. If an employee or contractor can leave with those materials, recreate them elsewhere, or sell a similar version to a competitor, the business may lose more than a tool. It may lose the operational advantage the tool created.
A strong confidentiality and proprietary rights agreement should treat these materials as company assets and trade secrets. It should also make clear that departing personnel must return company materials and cannot walk away with the company’s internal systems, prompt libraries, or automation playbooks.
When Ownership Problems Usually Surface
These issues often become visible at the worst possible time. The first common moment is when someone leaves. A contractor may finish a flagship automation, get into a fee dispute months later, and claim they own the tool. A key employee may leave and take “their” prompt library or internal agents with them. Without clear written assignments, the company may end up in a fight over whether it owns the technology it built and paid for.
The second moment is during a financing, acquisition, or investor diligence process. Venture funds and private equity firms increasingly want to confirm that the company, not its founders, employees, contractors, or consultants personally, owns the technology on the balance sheet.
If the company’s IP chain of title has gaps, the consequences can be significant. A deal may be delayed. Reps and warranties may become harder to give. Investors or buyers may demand holdbacks, escrows, repricing, or additional cleanup before closing. In some cases, an ownership issue can put the deal at risk entirely.
Signed proprietary rights agreements are one of the simplest ways to show clean ownership. Their absence can become a major diligence problem.
What a Strong Proprietary Rights Agreement Should Cover
A good proprietary rights agreement is not just a generic template. It should be drafted to clearly capture the types of work and technology the company needs to own.
One of the most important details is present-tense assignment language. The agreement should say the individual “hereby assigns” rights to the company, not merely that they “agree to assign” rights later. That distinction can matter because “agree to assign” may leave the company with only a promise, not an actual transfer. The scope should also be broad enough to cover inventions, software, works of authorship, designs, prompts, models, workflows, and related know-how created in connection with the work.
The agreement should include a prior-invention carve-out so employees or contractors can identify what they already owned before joining or starting the engagement. This protects both sides and helps avoid future disputes over pre-existing work. State-law compliance also matters as some states, including California through Labor Code §2870, limit how far invention assignments can reach into an employee’s personal, off-the-clock work. Agreements that ignore those limits may be partially unenforceable. A strong agreement should also include confidentiality and trade-secret protections, a moral-rights waiver, an obligation to return company materials at departure, and a further assurances clause requiring cooperation on future filings or transfers.
Most importantly, the agreement should cover everyone who builds. That includes employees, contractors, consultants, freelancers, agencies, and outside developers. The contractor gap is often where companies are most exposed.
Why This Matters for Growing Companies
In the AI era, many companies are creating proprietary technology without realizing it. They may not call it software. They may call it a workflow, an automation, a prompt library, an internal agent, or an efficiency tool. But if it makes the business faster, better, or harder to replicate, it may be valuable company IP.
The law will not automatically hand the company clean ownership of that technology, especially when contractors are involved or when AI-generated work is part of the process. The practical fix is simple: get the right agreements signed before there is a dispute, a departure, or a diligence request.
Putting proprietary rights agreements in place is faster and less expensive than fighting over ownership later. It is also one of the highest-leverage legal steps a growing business can take as AI becomes part of everyday operations.
FAQ
What is a proprietary rights agreement?
A proprietary rights agreement is a contract that assigns ownership of work, inventions, software, confidential information, and related intellectual property to the company. It is often also called a Proprietary Information and Inventions Assignment Agreement, IP assignment agreement, or confidentiality and proprietary rights agreement.
Does a company automatically own code a contractor writes?
Not always. When an independent contractor builds software or custom technology, the company may not own the copyright without a signed assignment. The company may only have a license to use the work, which can create problems later.
Do employees automatically assign inventions to their employer?
Not always. Employee-created copyrightable work may be owned by the employer if it is created within the scope of employment, but patentable inventions are different. Without a written agreement, the invention may belong to the individual who created it.
Who owns AI-generated work?
Purely AI-generated material without meaningful human authorship may not be eligible for copyright protection. However, the surrounding architecture, code, workflows, prompt engineering, fine-tuning data, configurations, and human curation may still be valuable assets that should be protected.
Why do investors care about proprietary rights agreements?
Investors and buyers want to confirm that the company owns the technology it claims to own. Gaps in the IP chain of title can create diligence issues, delayed closings, reps-and-warranties problems, holdbacks, escrows, repricing, or deal risk.
