Open the CIPO recordAbstract From the Canadian patent
A process for laser joining a first metal having a first reflectance curve as , a function of wavelength such as nitinol or stainless steel, and a second metal, having a second reflectance curve such as gold. The process comprises , placing the first and second metals in contact with one another then exposing at least one of the first metal and second metal to a laser beam having a wavelength selected from an optimal range of wavelengths over which the reflectance curves of the two metals essentially overlap. The first metal may comprise a first metal element having a sufficiently low heat sink capacity and a sufficiently lesser reflectance than the second metal at wavelengths …

Why it's free to use
- Filed December 11, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 11, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 11, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
