Open the CIPO recordAbstract From the Canadian patent
The aim of the present invention is to provide a method and a device for processing and in, particular, for polishing and texturing workpieces by, means of which arbitrary 2D and/or 3D shaped surfaces can be processed. The processing is performed by means of a laser beam. The actual surface shape and surface texture are determined before processing by means of a 3D contour-measuring device. Processing parameters are calculated from the desired surface shape and the surface shape actually measured, and the processing is carried out subsequently as appropriate.

Why it's free to use
- Filed April 9, 1996 and granted October 2, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 9, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 9, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
