NovaRay’s intellectual
property strategy is important to maintaining
the company’s technology lead. NovaRay had 23 issued U.S. patents and has
filed several international patents in Western
Europe and Japan. We believe our success in obtaining
patents demonstrates that our technology is substantially
different from the technology used in other medical
imaging systems enabling NovaRay to generate a
broad patent portfolio primarily around various
aspects of the x-ray source, detector, and image-reconstruction,
including:
| •
|
Target/coolant/collimator
apparatus |
| • |
X-ray source
construction |
| • |
Detector
apparatus |
| • |
Electron-beam
scanning apparatus and method |
| • |
Image-reconstruction
apparatus and methods |
| • |
Locating
catheter apparatus |
NovaRay believes that the company also has substantial
protection through trade secrets and know-how
regarding manufacturing processes, algorithms,
software, and materials selection.
