Open the CIPO recordAbstract From the Canadian patent
The present invention provides a method and device for measuring granule impact strength by vibrating a small container of granules at a wellcontrolled amplitude in order to inflict reproducible damage to the granules. Damage to the granules is measured as a function of time and amplitude. The measurements obtained yield a highly reproducible means for characterizing granule attrition and fragmentation.

Why it's free to use
- Filed July 22, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 22, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 22, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
