Open the CIPO recordAbstract From the Canadian patent
A reverse bias voltage in combination with selective illumination can selectively write data into optical memory (300). The writing process can be completed quickly since parallel writing of data may be performed. The writing process generates an avalanche current (208) that is used to change an element. The change can be destruction of the element or may be alteration of property such as conductance or work function (206).

Why it's free to use
- Filed May 24, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 24, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 24, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
