Open the CIPO recordAbstract From the Canadian patent
An office chair has multiple moving parts and controls for the different moving parts of the chair. The chair includes a control directory which is in a more visibly accessible position than the controls to a person sitting in the chair. The chair further includes control switches which when activated provide a guide to distinguish which particular set of instructions on the directory pertains to each of the controls. The control switches are activated without producing operation of the actual controls.

Why it's free to use
- Filed July 27, 2004 and granted October 14, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 27, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 27, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
