A surgeon designs a better retractor because the existing ones do not work for the approach they use. An interventional cardiologist modifies a delivery system mid-case. An anesthesiologist builds a monitoring workflow that catches something the standard alarms miss.
All three own their invention under the default rule of U.S. patent law, which gives ownership to the inventor. And all three may have signed that ownership away years ago without registering it.
Where the Claim Comes From
Employment agreements. Hospital and health system physician agreements frequently include invention assignment provisions. Scope varies enormously. Some reach only inventions made using institutional resources. Others reach anything related to the institution's field of activity, which for a health system is broad enough to cover most medical devices.
Institutional IP policies. Often incorporated by reference into the employment agreement, sometimes amended unilaterally, and frequently never read. The policy typically governs in more detail than the agreement itself.
Academic appointments. A clinical faculty appointment at an affiliated medical school can carry the university's IP policy alongside the hospital's. Physicians with dual appointments may be subject to two policies, and the institutions may have an agreement between themselves allocating rights.
Federal funding. If any part of the development touched federally funded research, the Bayh-Dole Act applies. The institution generally may elect title, with disclosure obligations to the funding agency and a retained government license. This applies to the research, not to your employment status, and it catches people who did not think of their device as a research output.
Residency and fellowship agreements. Trainees sign these quickly during onboarding. They frequently contain assignment provisions.
The recurring pattern: a physician develops a device over three years, forms a company, raises money, and discovers during diligence that their employer has a colorable claim to the core patent. Unwinding that after the fact is expensive and sometimes impossible.
What to Check, Specifically
Before filing anything, get copies and read them:
Your employment agreement, including every amendment and any document it incorporates by reference.
The institution's current IP policy. Ask for it in writing. Note the version and date, because policies change and the version in force when you invented is generally what governs.
Any research agreements you have signed, including sponsored research, material transfer, and clinical trial agreements.
Your medical school or university appointment terms, if you hold one.
Consulting agreements with industry. Device company consulting agreements routinely assign inventions arising from the engagement, and the definition of what arises from it can be broad.
Then work out the answers to these questions:
- Does the policy reach inventions made outside work hours and without institutional resources?
- Is it limited to the institution's field of activity, and does your device fall inside it?
- Did you use any institutional resources, including facilities, equipment, staff time, or patient data? This is the trigger in most policies and the bar is often lower than physicians assume.
- Was any of the underlying work federally funded?
- What is the disclosure obligation, and what is the deadline?
The Disclosure Obligation Is a Trap
Most institutional policies require you to disclose inventions to a technology transfer office within a set period after conception, often before any public disclosure or filing.
Two consequences.
Failing to disclose when required is a breach of your agreement, independent of who ultimately owns the invention. It is not a technicality that goes unnoticed if the invention later becomes valuable.
But disclosing starts a process you may not control. The institution evaluates, decides whether to elect title, and if it does, decides how to prosecute and license. Timelines are often slow relative to the patent deadlines you are facing, and slow is dangerous when you have a conference presentation scheduled.
Understand the process before you trigger it, and get advice on sequencing rather than improvising.
When the Institution Does Own It
This is not necessarily bad news, and physicians sometimes overreact to it.
Institutions often release inventions they do not want to pursue. Many technology transfer offices are selective, and a formal release is common when the invention does not fit their portfolio. Ask.
Inventor revenue sharing is standard. Most policies provide the inventor a meaningful share of licensing revenue, frequently in the range of a third to half after expenses. That is real money on a successful device, without you funding prosecution.
The institution pays for prosecution. Patent costs across a family over its life are substantial. Institutional funding removes that.
They may license back to your startup. If you intend to commercialize yourself, negotiating an exclusive license from your institution is a well-worn path. Terms are negotiable, and negotiating before the invention has proven value is generally easier than after.
The outcome you want to avoid is not institutional ownership. It is unresolved ownership discovered during a financing or an acquisition, when the institution has leverage and you have a deadline.
If You Are Leaving
Timing questions get sharp around departure.
Inventions conceived during employment generally belong to the employer under the applicable policy, regardless of when you file. Filing after you leave does not change when you conceived.
Many agreements include a trailing clause reaching inventions made for some period after departure, typically six to twelve months, if they relate to work done during employment. These are enforceable in many states, and they are frequently overlooked.
Document your conception dates contemporaneously. Dated, witnessed records of when you conceived what are the evidence that resolves these disputes, and they are far more persuasive created at the time than reconstructed later.
What To Do
- Read the documents before you file anything. All of them.
- Determine whether an obligation to disclose has already been triggered, and when.
- Get advice on sequencing the institutional disclosure against your patent deadlines, especially if a conference or trade show is scheduled.
- Document conception contemporaneously, with dates and witnesses.
- If the institution has a claim, engage it early, when you have more leverage and more time than you will later.
- If you are forming a company, resolve ownership completely before you raise. Investors will find it. See what investors check in IP diligence.
