Open the CIPO recordAbstract From the Canadian patent
A linear beam amplification device includes an axially centered electron emitting cathode and an anode spaced therefrom. The cathode provides an electron beam in response to a relatively high voltage potential defined between the cathode and the anode. A control grid is spaced between the cathode and anode for modulating the electron beam in accordance with an input signal. A signal input assembly of the linear beam amplification device comprises an axial input cavity into which the input signal is inductively coupled. The grid-cathode region is electrically connected to the input cavity. A low impedance grid-anode cavity is disposed coaxially with the input cavity and is in electrical …

Why it's free to use
- Filed March 24, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 24, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 24, 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.
