The added scripting language (114) refers to a number of image objects/files that have been selected to form a compound image (when juxtaposed). The compound image is unique to one of the sets.

Why it's free to use

  • Filed June 21, 2005 and granted April 8, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 21, 2025.
  • 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.
