Open the CIPO recordAbstract From the Canadian patent
A dosing form for a polymer support for organic chemical synthesis in a solvent medium comprising a fixed weight amount of beads of a polymer containing functional groups, which polymer is insoluble in the solvent for the intended synthesis, is provided as compressed tablets of essentially equal weight and composition wherein the polymer beads are essentially intact and are released as such when the tablets are disintegrated in said solvent. Use of the dosing form is made in conventional synthesis in parallel synthesis, in split and mix synthesis and/or combinatorial chemistry. In a method for producing the dosing form, beads of a polymer having functional groups are compressed into …

Why it's free to use
- Filed March 16, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 16, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 16, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
