Abstract From the Canadian patent

In a peer-to-peer fashion, various host computers communicate with various remote computers using the Internet so that user inputs from the remote computers are transferred to the host computers as if the user inputs occurred locally, and information generated by the host computers is displayed on the remote computers. Thus, a remote computer is able to access all of the information and application programs on the host computer.

  • Filed September 6, 2005 and granted March 20, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 6, 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.
