Abstract From the Canadian patent

A system in which a plurality of network nodes are connected through a network, wherein when a computation object of a first network node calls a function (facility) of a computation object of a second network node, the first network node obtains a facility identification codes (numeral) of the object and the function from a remote reference table and outputs the facility identification codes through the network as a message together with the arguments of the function to the second network node. The second network node uses the input facility identification code as a key to obtain the execution address of the facility from a local reference table and executes that facility.

Why it's free to use

  • Filed March 4, 1997 and granted April 23, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 4, 2017.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 4, 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.
