Open the CIPO recordAbstract From the Canadian patent
An element has been prepared which is useful for the detection of nucleic acids in various formats. The element has a sealable support on which is disposed a nucleic acid reagent composition. The composition is a mixture of a nucleic acid reagent composed of polymeric particles to which an oligonucleotide is covalently attached. The particles are prepared from a first polymer having a glass transition temperature of at least 70 ·C and have an average diameter of from 0.1 to 3 micrometers. The reagent is adhered to the support using a water insoluble adhesive comprising a second polymer which has a glass transition temperature which is at least 30 ·C less than the glass transition …

Why it's free to use
- Filed March 19, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 19, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 19, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
