A system for synchronizing application programs which together provide a multimodal user interface, which comprises multiple application programs which provide the various interface of the multi-modal interface and which are in communication with a synchronization manager. Means are provided to detect status changes in the application programs and to communicate such status changes, in the form of data updates to the synchronisation manager. The synchronization manager is operative to communicate such a data update to the application program in which the data update did not originate so that the application programs are synchronised.

Why it's free to use
- Filed April 2, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 2, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 2, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
