Open the CIPO recordAbstract From the Canadian patent
A device, such as a cellular phone, is provided having a component, e.g. a device housing, containing an integral light guide where the component is formed by co-injection molding. The integral light guide is capable of distributing light from one or more sources through or along the component to distant keys or a distant liquid crystal display, thereby reducing the required number of light sources in the device. In addition, because the component and light guide are coinjection molded in a single step, the complexity and cost of the manufacturing of the component, and thus the overall device is typically, reduced.

Why it's free to use
- Filed April 12, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 12, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 12, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
