Open the CIPO recordAbstract From the Canadian patent
A base end portion of a lower arm is mounted on a revolutionarily drivable revolution portion at a specific offset from the revolutionary axis thereof and, an upper arm is mounted in the lower arm with the lower, and upper arms being rotationally drivable within a plane parallel to the revolutionary axis. Since the upper arm is offset from the revolutionary axis, both right-handed operation and left-handed operation can be easily selected, and the work range of this robot can be increased while its installation space can be reduced.

Why it's free to use
- Filed June 5, 1991 and granted February 11, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 5, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 5, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
