Open the CIPO recordAbstract From the Canadian patent
A sidewise loading disc jacket, eg a compact disc jacket, is designed to accommodate a disc shaped body which moves in and out the jacket linearly through opening and closing a door hinged at the edge of the jacket. When the design is adopted for storing compact disc, the size of this jacket can be made identical to the traditional compact disc jacket so that it can be kept in conventional compact disc racks. By doing so the compact disc can be stored in or taken out from the jacket without removing the jacket from the rack.

Why it's free to use
- Filed April 7, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 7, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 7, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
