Spectros has 80 US and international patents and counting...

Spectros and its affiliates have over 80 patents issued, licensed, or filed worldwide for molecular sensing, detection, and imaging, forming one of the largest biophotonics intellectual property collections.
Our innovative approach centers on key patented core technology families, covering optical spectroscopy, fluorimetry, and imaging for use in blood analysis, contrast-targeted cancer surgery, lab-on-chip systems, and benchtop life-sciences equipment. Based on these technology families, Spectros develops, markets, and licenses a number of medical and industrial optical products and processes, including OEM components and devices and medical devices both under study and on the market.
Because of this, Spectros aggressively defends its technologies and products against infringement, including:
