The first identifier enables a determination of a type of information that is included within the received link vertex information. The method also includes determining the type of information included within the received link vertex information based on the first identifier and identifying vertex components within the link vertex information only if the first identifier enables a determination that the received link vertex information includes at least one vertex component.

Why it's free to use

  • Filed May 18, 2006 and granted March 31, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 18, 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.
