Knechtel Law Group represents medical device companies before the USPTO nationwide from Carefree, Arizona. For Chicago founders and in-house teams, that means patent counsel who reads the clinical problem, the engineering, and the claims together.
Few regions put a small device company this close to so many large, diversified incumbents. Abbott keeps its corporate headquarters in Abbott Park in Lake County, Baxter is based in suburban Deerfield, Medline operates from Northfield, and GE HealthCare has run its corporate headquarters from downtown Chicago since becoming an independent public company in January 2023. Between them, those companies cover diagnostics, infusion and renal therapy, imaging, and hospital supply. A startup developing in any of those categories should assume it is working next to mature patent portfolios and plan its filings and freedom-to-operate reviews accordingly.
The research base leans toward sensing, bioelectronics, and rehabilitation. Northwestern University's Querrey Simpson Institute for Bioelectronics develops soft, skin-mounted wireless systems, including vital-sign sensors investigated for neonatal care. Shirley Ryan AbilityLab, formerly the Rehabilitation Institute of Chicago, opened its research hospital in 2017 around the idea of placing clinicians, scientists, and technologists alongside patients. The Chicago Biomedical Consortium supports collaboration among Northwestern, the University of Chicago, and the University of Illinois Chicago.
The company-building infrastructure is equally specific. iBIO, the Illinois Biotechnology Innovation Organization, is the state's life sciences industry association, with members across biopharma, medical device, and nutrition. MATTER, a healthcare technology incubator, opened in 2015. mHUB, a hardtech innovation center, runs a MedTech accelerator that gives early device teams access to prototyping labs and fabrication support.
Those features translate into concrete patent questions. Inventions that begin in university labs carry institutional ownership and license terms that should be settled before financing. Wearable and sensor platforms mix hardware, firmware, and analytics, so claims need to be anchored in the physical system rather than the data alone. Prototyping in shared facilities makes invention records and confidentiality discipline worth attention from day one. And if a dispute is ever filed in the Northern District of Illinois, the court's Local Patent Rules, in place since 2009, set a structured schedule for contentions and claim construction, which rewards claims drafted with enforcement in mind.
Patent Strategy Considerations
Amendments to the Illinois Freedom to Work Act that took effect in 2022 bar non-compete agreements for employees below set earnings thresholds, which step up over time. The amendments do not reach confidentiality or invention assignment covenants, so Illinois device companies should rely on well-drafted assignment and confidentiality agreements, backed by timely patent filings, rather than on non-competes to keep engineering know-how in the company.
When a product sits in a category occupied by large incumbents, the patent plan should include an early freedom-to-operate review, design-around options documented during development, and claims aimed at the specific technical advance rather than the general product class. That approach supports both clearance and investor diligence.
For wearables and connected monitoring systems, USPTO subject-matter eligibility guidance makes it important to tie claims to the sensor architecture, signal processing, and measurable technical improvement. Layered claim sets covering the device, the system, and the method of use give a portfolio more than one path to cover a competitor's product.
How Engagements Work
Knechtel Law Group is based in Carefree, Arizona. Patent prosecution and counseling before the U.S. Patent and Trademark Office is federal practice, and engagements with Chicago-area companies are handled directly by senior counsel by video and in person as needed. Matters that turn on state law may call for local counsel.

Not for USPTO work. Patent prosecution is a federal practice, and a registered patent attorney may represent applicants before the USPTO regardless of where the attorney or client is located. Questions governed by Illinois law, such as employment covenants or state-court contract disputes, and litigation in Illinois courts may call for counsel admitted there, and we can coordinate with local counsel when that arises.
Yes. The district adopted Local Patent Rules effective in 2009, which set the sequence and timing of initial disclosures, infringement and invalidity contentions, and claim construction. Knowing that framework in advance is one reason to draft claims and keep development records with eventual enforcement in mind.
Confirm the scope of the license field, who controls prosecution and pays costs, whether improvements made at the company are covered, and any diligence milestones. Those terms determine what the company actually owns and are routinely examined by investors and acquirers.
