Open the CIPO recordAbstract From the Canadian patent
The invention relates to a combined method in which a high-resolution image of a sample surface is recorded by means of scanning force microscopy and the locally high-resolution chemical, nature (which is correlated with this) of the sample surface is measured by means of mass spectroscopy. The surface is chemically analyzed on the basis of laser desorption of a restricted surface area. For this purpose, the surface is illuminated in a pulsed form at each point of interest using the optical near-field principle. The optical near-field principle guarantees analysis with a position resolution which is not diffraction-limited. A hollow tip of the measurement probe that is used allows …

Why it's free to use
- Filed July 24, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 24, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 24, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
