Abstract From the Canadian patent

An operation management system for managing the operation of a managed software product. When a management target function is executed, reference is made to a battery value and if the value is zero or greater, the function is allowed to be executed. The battery value is decremented as the function is executed. A charge value is supplied on a charge disk such, as a floppy disk, to allow the user to increase the battery value and to extend the usage period of the managed software product. The charge valuemay be supplied over a communication line.

Why it's free to use

  • Filed July 7, 1997 and granted December 2, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 7, 2017.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 7, 2019.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
