Open the CIPO recordAbstract From the Canadian patent
A noncontact method and apparatus for testing electrical circuitry which provides large improvements in both resolution and speed. The attributes of noncontact, high resolution, and speed are satisfied by using inexpensive low intensity resonant laser beams in a shroud has preferably comprising rubidium atoms in argon gas to create an electrically conductive ion channel microprobe. The conductive ion channel microprobe can be used to create an electrically conductive path between a circuit's test pad or point and signal generation and detection apparatus. If the circuit's test pad or point is functioning properly, then the ion channel microprobe will complete the electrically …

Why it's free to use
- Filed June 13, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 13, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 13, 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.
