In the fast-evolving world of healthcare, medical inventions including everything from groundbreaking surgical devices and pharmaceuticals to digital health solutions, are transforming patient care and industry standards. But with innovation comes the critical need for protection. Medical patents are the legal lifelines that safeguard these inventions, ensuring that healthcare professionals, inventors and companies can reap the rewards of their innovation. This article explains what a medical invention is, what medical patents entail, and why hiring an experienced medical patent attorney is essential for securing robust protection for your invention.
What Is a Medical Invention?
A medical invention is any new and useful process, machine, manufacture, or composition of matter that addresses a healthcare challenge. Medical inventions span a wide range, including:
-
Medical devices (surgical instruments, diagnostic equipment, implantable devices, prosthetics, and more)
-
Pharmaceuticals (new drugs, drug delivery systems, and formulations)
-
Medical software and digital health tools (software-based systems, AI-driven diagnostics, telemedicine platforms, and patient monitoring and diagnostic systems)
Medical Patents covering medical inventions must meet three core criteria to qualify for patent protection: they must be novel (not previously disclosed or publicly available), non-obvious (not an obvious improvement to someone skilled in the field), and useful (serve a practical purpose in healthcare).
It is important to note that under U.S. law and in many other jurisdictions, surgical techniques and medical procedures are generally not eligible for protection as medical patents. This exclusion is rooted in public policy: allowing patents on medical procedures could restrict access to life-saving treatments and create ethical dilemmas for healthcare providers. Courts and patent offices have consistently held that methods of treating the human body, such as surgical steps or diagnostic methods performed directly on patients, are generally not patentable subject matter.
What Is a Medical Patent?
A medical patent is a government-granted right that gives the inventor exclusive control over the use, manufacture, and sale of their medical invention for a defined period-typically 20 years for utility patents in the United States. This exclusivity is a powerful incentive for innovation, allowing inventors to recover their investment and profit from their work while preventing others from copying or exploiting their invention without permission.
Medical patents can cover a range of innovations, including:
-
Utility patents for functional aspects of devices, drugs, or processes
-
Design patents for the ornamental appearance of medical devices
-
Plant patents (less common in healthcare, but relevant for botanical pharmaceuticals)
Patents do not grant the right to market or use a medical product-regulatory bodies like the FDA oversee that process-but they do provide a legal barrier against competitors who might otherwise copy or commercialize your invention.
Ten (+) Medical Patent Stories
1. Stethoscope (1816, René Laennec, France)
Though the earliest stethoscope was not patented in the modern sense, René Laennec’s invention of a wooden tube to amplify heart and lung sounds in 1816 revolutionized diagnostics. Later versions of the stethoscope received medical patents as the device evolved, making it a symbol of clinical medicine and a foundation for patient assessment worldwide
2. X-ray Machines: An Accidental Breakthrough (1895, Wilhelm Conrad Röntgen, Germany)
Wilhelm Conrad Röntgen’s accidental discovery of X-rays in 1895 led to the first medical imaging technology. While Röntgen did not patent his initial invention, commercial X-ray machines were quickly patented, forever changing diagnostics and enabling non-invasive visualization of the body’s internal structures
3. Iron Lung: Saving Lives from Polio (1927, Philip Drinker, USA)
Philip Drinker invented the iron lung in 1927 to help patients paralyzed by polio breathe. The device was patented and mass-produced, saving countless lives during the polio epidemics of the mid-20th century. The iron lung’s story illustrates how medical patents can drive rapid adoption and public health impact.
4. Insulin: From Discovery to Global Treatment (1921, Frederick Banting & Charles Best, Canada)
The discovery of insulin in 1922 at the University of Toronto was a medical miracle because it made Type 1 diabetes a manageable condition. While the original process was not patented in the U.S. (the inventors sold their rights for $1 each to the University of Toronto, believing insulin belonged to the world ), subsequent improvements in insulin formulations and delivery devices have received numerous medical patents. These medical patents have enabled continuous innovation, from injectable insulin to advanced insulin pumps, improving the lives of millions with diabetes.
5. Cochlear Implant (US Patent No. 3,751,605, 1973, William House, USA)
William House’s received medical patents for his cochlear implant, patented in 1973, restored hearing for individuals with profound deafness. The device’s patent protected its unique design, paving the way for further advancements in auditory prosthetics and improving quality of life for millions.
6. Artificial Kidney/Dialysis Machine (US Patent No. 2,664,366, 1953, Willem Kolff)
Willem Kolff’s artificial kidney, patented in the U.S. in 1953, was the first practical dialysis machine. This invention allowed patients with kidney failure to survive and thrive, transforming renal care and inspiring generations of medical device innovation
7. Polymerase Chain Reaction (PCR) (US Patent No. 4,683,195, 1987, Kary Mullis)
Invented by Kary Mullis in 1983 and patented in 1987 (US Patent 4,683,195), PCR revolutionized genetics, diagnostics, and forensic science by enabling rapid DNA amplification. The patent was later acquired by Roche for $300 million, underscoring the commercial value of well-protected medical inventions. PCR is now essential for genetic testing, disease diagnosis, and forensic science.
8. CRISPR Gene-Editing System (US Patent No. 10,000,772 – 2018)
CRISPR technology, patented in the U.S. in 2018, allows precise editing of DNA, opening new frontiers in genetic medicine, agriculture, and biotechnology. The patent landscape for CRISPR is complex and highly contested, reflecting its immense scientific and commercial potential.
9. Pacemaker (US Patent No. 3,057,356 – 1962, Rune Elmqvist, Sweden)
Rune Elmqvist’s implantable pacemaker, patented in the U.S. in 1962, regulates heart rhythm and has saved millions of lives. The pacemaker’s patent enabled widespread adoption and continuous improvement, making it a cornerstone of cardiac care.
10. Birth Control Pill (US Patent No. 2,563,794 – 1951,Gregory Pincus, et al., USA )
The birth control pill, patented in 1951, transformed reproductive health and women’s rights. Its patent protected the synthesis and formulation of synthetic hormones, enabling global access and empowering individuals to plan their families.
11. MRI Technology (US Patent No. 4,343,993, 1982, Raymond V. Damadian, USA)
Raymond Damadian received a Nobel Prize (and a patent US 4,343,993) for his work on a technique using nuclear magnetic resonance to distinguish between normal and cancerous tissue. This breakthrough led to the development of the MRI (magnetic resonance imaging) machine, which has become indispensable for non-invasive diagnosis of a wide range of conditions. Damadian’s story is a reminder that medical device patents can change the course of medicine and save countless lives.
