Abstract From the Canadian patent

By modeling real-world application objects with complex structures behaviors, and operations described by a schema which is enforced by the hardware/software interface system, various embodiments of the present invention provide rich sub-typing functionality (3602 3604, 3606, 6322, 3624, 3626, 3642, 3644) by extending Items using extensions which provide additional data structure to already existing items type structures. Extensions are strongly typed instances that cannot exist independently and must be attached to an item or a Nested element. Extensions are also intended to address multityping issues by enabling the overlap of type instances.

Why it's free to use

  • Filed July 29, 2004 and granted January 20, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 29, 2024.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 29, 2026.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
