Open the CIPO recordAbstract From the Canadian patent
A collapsible conductive material includes a mesh-configured collapsible surface, that defines the reflective geometry of an antenna and a distribution of tensionable cords and ties, which attach the reflective mesh to an inflatable support structure. The antenna is deployed once the inflatable support structure is inflated to at least a minimum pressure necessary to place the attachment tie/cord arrangement in a tension that causes the reflective surface to acquire a predetermined (e.g. parabolic) geometry. Preferably the inflation, pressure is above the minimum value so as to allow for pressure variations (drops) within the support structure.

Why it's free to use
- Filed June 25, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 25, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 25, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
