Open the CIPO recordAbstract From the Canadian patent
The field effect transistor includes a control terminal (G) a first main, terminal (S) and a second main terminal (D1). The control terminal (G) is included to be coupled to gate voltage means which. are adapted to provide a control voltage (V g) which controls a flow of carriers (e) flowing from the first, main terminal (S) to the second main terminal (D1). The field effect transistor, further includes a third main terminal (D2) which is positioned and adapted in order to enable a high. input resistance control current means (CS) which is, coupled to the third main terminal (D2) to deviate part (e') of the flow of , carriers from the first main terminal (S) to the third main terminal …

Why it's free to use
- Filed April 30, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 30, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 30, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
