Open the CIPO recordAbstract From the Canadian patent
Cells and non-human transgenic animals have been engineered to be deficient in the gene encoding the melcanocortin-4 receptor protein (MC-4R). These MC-4R deficient transgenic animals can be used to select for and test potential modulators of MC-4R. This data allows for methods of screening for preferential MC-4R modulators which effect body weight through modulation of both metabolic rate and food intake, as well as associated methods of treating various disorders associated with inappropriate regulation of body weight.

Why it's free to use
- Filed November 13, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 13, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 13, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
