Open the CIPO recordAbstract From the Canadian patent
A spa cover remover has a pair of parallel side bars pivotably connected to opposite sides of a spa and a cross-bar in the form of a roller extending between upper ends of the side bars. In use a spa cover is folded over the cross-bar during removal from a spa and the side bars and the cross-bar are then pivoted to lift the cover into an offset position. During such pivotation rotation of the roller prevents stretching and consequential damage of the covering of the spa cover.

Why it's free to use
- Filed September 8, 1999 and granted July 2, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 8, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 8, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
