Open the CIPO recordAbstract From the Canadian patent
A liner (38) for a body (10) such as of an off-highway truck protects the body (10) from wear. The liner (38) has a plate (40) with openings (50) through the plate (40) arranged in a preselected pattern. The plate (40) is of a size to fit a particular portion of the body (10) and is typically removably fastened to the body (10). The openings (50) in the plate (40) cause material to tumble, instead of to slide, when being removed from the truck (14). The tumbling action, and the thickness of the plate (40) reduces wear on the body , (10) during material dumping.

Why it's free to use
- Filed November 12, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 12, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 12, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
