OCT is a non-invasive imaging technique widely used in the medical world, especially in ophthalmology and vascular/cardiology”, explains Dr Brice Sagot, Knowmade’s COO. “Its development began 25 years ago, under MIT’s impetus. Since then, OCT imaging technologies and capabilities have greatly evolved.”Considering the significant impact this technology had on the diagnostics and monitoring of diseases in ophthalmology and the intravascular domain, developments are underway to expand OCT to other medical applications including gastroenterology, dermatology, and gynecology.
Yole Développement, part of Yole Group of Companies as well, estimates a 7.3% CAGR (in units) growth for the OCT equipment sales between 2017 and 2022. Intravascular should bring additional OCT equipment volume while ophthalmology OCT will continue to enjoy a steady growth. In parallel, new development in dental and dermatology should expand OCT application’s scope.
Patent activity related to OCT medical imaging emerged in the 1990s with MIT. Today, OCT medical imaging’s IP landscape represents over 4,850 families, including more than 13,350 patents. The landscape is very competitive, with several key IP players. Main current applicants in the field of OCT medical imaging include Abbott, Canon, Novartis, Philips, Topcon and Zeiss.
Many patent applicants are American and Japanese companies and main countries targeted by these players are USA and Japan. However, China and Europe have gaining importance in the last decade.
“Noteworthy, we observe the absence of Chinese applicants, such as MOPTIM or SUOER, among the main applicants”, asserts Dr Le Greneur from Knowmade. “Chinese applicants do not currently show a high IP leadership in OCT technologies.”
In the early 2000s, two applications were present: intravascular/cardiovascular and ophthalmic. Since 2005, the number of patents related to OCT for ophthalmology has increased greatly. Other medical applications are today in an emerging phase, but offer potential benefits once resolution and speed-of-image acquisition improve. The 4,850 patent families selected for Knowmade study are categorized by main medical applications. In this new patent landscape report, the company reveals IP strategies and technical choices of patent assignees:
• Ophthalmic applications are dominant in OCT technology and involve several main applicants, including Canon and Zeiss.
• The second-most popular OCT medical application is cardiovascular imaging. This domain involves totally different applicants compared to ophthalmology.
And more recently, new medical applications for OCT have been developed, including dermatology, gastroenterology, gynecology, and dentistry…
Knowmade releases this month a new patent landscape analysis titled, Optical Coherence Tomography Medical Imaging. This report provides a ranking and detailed understanding of the top patent holders’ relative strength, derived from their portfolio size, patent citation networks, countries of patent filings, and current legal status of patents. Through this in-depth analysis the technology intelligence & IP strategy consulting company has identified more than 15 major players, each of which is profiled in the OCT report. Each profile includes a detailed portfolio analysis with patent activities, key patents, portfolio impact, and IP strategies.
