Open the CIPO recordAbstract From the Canadian patent
SOD and other active oxygen inhibitors are directly applied in combination with a barrier material at local sites of tissue injury to prevent or decrease formation of adhesions and undesirable profileration of cells. Preferred barrier materials are polymeric hydrogels providing controlled release of AOI which are directly applied to the afflicted tissue. Examples demonstrate the effects of SOD on pelvic adhesions in the rat when administered by intraperitoneal (IP.) bolus and by localized sustained release from a topically applied hydrogel system.

Why it's free to use
- Filed March 20, 1996 and granted July 23, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 20, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 20, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
