Open the CIPO recordAbstract From the Canadian patent
A screening method for preliminary indication of the diabetic state in mammals comprises an assay of urine samples collected from suspect patients for the presence of D-chiroinositol. The absence of D-chiroinositol indicates an absence of insulin mediators and therefore a diabetic condition. The assay may be used to detect genetic predisposition to the development of diabets in asymptomatic individuals.

Why it's free to use
- Filed March 8, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 8, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 8, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
