Abstract From the Canadian patent

A high frequency applicator for energizing electrodeless lamps is described. The applicators are made of two loops of wire electrically attached to the ends of phased feed points of a planar transmission line.

Each loop is made of three partial turns, the first and second turns being parallel to each other, each partial turn having a first and second end and the third partial turn is attached to the second end of each partial turn and positioned orthogonal the first and second turns.

Why it's free to use

  • Filed August 25, 1992 and granted December 7, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 25, 2012.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 25, 2014.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
