Open the CIPO recordAbstract From the Canadian patent
A method of determining the arrival time of one or more ions at an ion detector is disclosed. Ions arriving at the ion detector produce a signal and the time when a leading edge of the signal and when a trailing edge of the signal cross an intensity threshold are determined. The two times are then averaged to provide an ion arrival time.

Why it's free to use
- Filed August 11, 2004 and granted May 14, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 11, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 11, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
