Open the CIPO recordAbstract From the Canadian patent
An allogenic implant (10) for use in intervertebral fusion is formed from two parts. The first part (20), composed of cortical bone provides mechanical , strength to the implant allowing the proper distance between the vertebrae being treated to be maintained. The second part (30) composed of cancellous , bone, is ductile and promotes the growth of new bone between the vertebrae being treated and the implant, thus fusing the vertebrae to the implant and to each other. The implant is sized and shaped to conform to the space between the vertebrae. Teeth (12) formed on the superior (14) and inferior (16) surfaces of the implant prevent short-term slippage of the implant.

Why it's free to use
- Filed September 2, 2004 and granted February 7, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 2, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 2, 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.
