Optical Coherence Tomography Medical Imaging Patent Landscape: 2025 Overview
Optical Coherence Tomography (OCT) is a non-invasive imaging technique that uses light waves to produce detailed cross-sectional images of tissues, commonly used in ophthalmology, cardiology, and dermatology. With real-time, high-resolution capabilities, OCT is transforming diagnostics and surgical guidance. As demand for non-invasive and accurate imaging grows, the global OCT market is expanding rapidly.
In 2024, the global OCT medical imaging market was valued at USD 1,632.23 million and is expected to reach USD 3,880.32 million by 2032, growing at a CAGR of 10.1% (2025–2034). This growth is fueled by rising eye disease prevalence, technological advancements, and increased use of OCT in non-ophthalmic areas like oncology and cardiology. These trends are reflected in the growing number of patent filings as companies secure proprietary innovations.
OCT technology, based on low-coherence interferometry, has evolved significantly. Innovations span hardware (light sources, detectors), software (AI integration), and portability. These developments are actively patented as the industry moves from Time Domain OCT (TDOCT) to faster, higher-resolution Spectral Domain (SDOCT) and Swept-Source OCT (SSOCT).
Patent activity is particularly high in the U.S., which leads with around 22,000 filings. China is emerging rapidly due to investments in healthcare innovation, followed by Europe and Japan. Key players shaping the OCT patent landscape include:
* Philips: Focuses on real-time, AI-powered diagnostic systems.
* Nvidia: Leverages AI and GPU technology to enhance OCT imaging.
* Surgical Operations: Develops handheld, intraoperative OCT tools.
* Volcano Corp: Specializes in catheter-based cardiovascular OCT.
* Canon KK: Innovates in imaging sensors and optical design.
* Topcon Corp: Leads in retinal diagnostics and AI image analysis.
Startups and new entrants are driving growth in AI-based imaging, portable OCT devices, and surgical integration—marking a shift toward point-of-care and personalized medicine.
