Open the CIPO recordAbstract From the Canadian patent
A Distributed Object System includes an Event Collection Mechanism (14) which receives information on the creation, deletion and actuation of objects within the system. The Event Collection Mechanism passes on the collected events to an Event Dispatch Mechanism (16) with which user applications may register. The Event Dispatch Mechanism forwards details of events to the User Applications, according to the criteria selected by the user. A method is provided for linking all reported events back to the object which was ultimately responsible for their creation.

Why it's free to use
- Filed March 25, 1997 and granted February 18, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 25, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 25, 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.
