Open the CIPO recordAbstract From the Canadian patent
An apparatus for using the continuous-gradient disk diffusion technique to obtain quantitative minimum inhibitory concentrations and inhibitory quotients comprises an electronic caliper operatively coupled to a microprocessor for feeding thereto signals coding the diameters of bacteria-growth inhibition zones measured by the caliper. In response to the signals, the microprocessor automatically calculates by means of a regression-type analysis the minimum inhibitory concentrations of the drugs, as determinable based on a correlation with results by a broth dilution test with respect, to the bacterium under study. The microprocessor also calculates, in response to the signals from the …

Why it's free to use
- Granted January 31, 1989. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended January 31, 2006.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
