Compact Imaging Granted Three New Patents for Miniature OCT Technology

Expands IP Coverage in Small, Low-Cost, Non-Invasive Sensor for Mobile Health Monitoring and Fingerprint Authentication

Mountain View, CA—February 2, 2015—Compact Imaging, Inc. (CI), an early stage technology company developing proprietary miniature optical sensors for the rapidly growing mobile personal health monitoring and fingerprint authentication markets, today announced that it has been granted three additional patents in the field.  

CI’s intellectual property base, consisting of 14 US patents and numerous pending US and foreign applications, is centered on MRO™, the Company’s proprietary miniature version of optical coherence tomography (OCT). OCT is a well-established, non-invasive, non-ionizing imaging technology widely used in clinical diagnostic applications, according to Don Bogue, CEO. 

“Our miniature OCT architecture, MRO™, can be implemented within the size, cost, and power requirements of mobile and wearable devices,” he said.  “These new patents further expand our IP coverage of the space and offer partners and licensees robust protection for the investments they make in bringing products that incorporate MRO™ sensors to market.

“We continue to demonstrate the technical capabilities of the MRO™ system in human subject tests in a variety of consumer-oriented mobile health monitoring and fingerprint authentication applications. These new patents will add to the understanding, credibility, and protection of our approach.”

The three new patents are:

  • Hybrid OCT Scanning Device (US 8,851,675).
  • Non-Invasive Optical Monitoring (US 8,870,376).
  • Field of Light Based Device (US 8,888,284).

The imaging technology that underlies CI’s MRO™, optical coherence tomography (OCT), was first commercialized more than a decade ago.  Conventional OCT machines, which cost $50,000-$150,000 each, revolutionized medical diagnostic imaging but are large, complex and power hungry—well-suited for clinical use but far from mobile.  The MRO™ architecture is inherently miniature and will operate on battery power. Therefore, MRO™ sensor technology is ideal for integration in high volume consumer devices, such as smartphones and other devices used for personal health monitoring or requiring identity authentication.              

CI also recently announced the extension of its collaboration agreement with the Tissue Optics and Microcirculation Imaging (TOMI) laboratories at the National University of Ireland, Galway (NUIG).  Together, CI and NUIG researchers are working on the longer-term development and demonstration of MRO™ in an increasing range of non-invasive imaging and measurement applications involving both biological and non-biological targets.

CI, headquartered in Mountain View, CA, USA, is privately-held.

About Compact Imaging

Compact Imaging (CI) is an early stage technology company developing miniature optical sensors that non-invasively and directly image and measure sub-surface features, properties, and behaviors of human tissue and other biological and non-biological materials.  These sensors, called MRO™, which are inherently small, low cost and low operating power, will address the need for more capable and versatile sensors in rapidly expanding consumer device markets, such as mobile personal health monitoring and fingerprint authentication.   The Company has been issued a series of US patents covering its multiple-reference optical coherence tomography (MRO™) technology.
