Open the CIPO recordAbstract From the Canadian patent
An office panelling system is disclosed which readily accommodates the initial or retrofit of communication cables and the like cables which generally do not require an electrical conduit. The individual panels of the system have a metal framework to which decorative covers are secured. The framework and covers have been adapted to define a passageway along the panel which is accessible by removing of the covers. With this arrangement, communication cables may be installed without stringing of the cables through ports in the framework.

Why it's free to use
- Filed April 24, 1992 and granted January 23, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 24, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 24, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
