Abstract From the Canadian patent

A clip for accurately and quickly suspending pairs of spaced parallel grid main tees from superadjacent structural channels. The clip works with a separate drop clip that hooks over and depends from the structural channel. The paired main tee clip has a central body region configured like a conventional grid tee bulb thereby enabling the paired main tee clip to mate with the drop clip in the same way the drop clip mates with a conventional grid tee bulb thereby achieving a system that is cost-effective in manufacture and installation.

Why it's free to use

  • Filed April 24, 2006 and granted December 11, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 24, 2026.
  • Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
