A system that provides a graphical user interface showing relationships between effective dated objects in an object oriented system and showing modifications to the objects over time. The interface displays an effective dated tree control of persistent objects. The control shows past, current and future events associated with the objects represented in the control.

The objects can be selected ("clicked-on") and additional details of the objects are displayed.

Why it's free to use
- Filed July 26, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 26, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 26, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
