Abstract From the Canadian patent

A garment for protection against insects comprising an inner layer of material onto which an outer layer of mesh is placed. The inner layer is formed having a plurality of arches to elevate the outer mesh layer a distance from the user's skin. The outer mesh layer is impervious to insects while the distance defined by the arches prevents the insect's stinger or proboscis from reaching the skin. In an alternative embodiment, the inner layer is also made of mesh with a series of heat shrinkable polymeric strands running therethrough which are heat-treated to cause the inner layer to form a series of arches.

Why it's free to use

  • Filed March 12, 1997 and granted June 27, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 12, 2017.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 12, 2019.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
