Abstract From the Canadian patent

The present System and method for simulating particles and waves is useful for calculations involving nuclear and full spectrum radiation transport quantum , particle transport, plasma transport and charged particle transport. The invention provides a mechanism for creating accurate invariants for embedding in general three-dimensional problems and describes means by which a series of simple single collision interaction finite elements can be extended to formulate a complex multi-collision finite element.

Why it's free to use

  • Filed February 24, 2005 and granted September 29, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 24, 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.
