The present invention relates to a method and system for textual exploration and discovery. More specifically, the method and system provide a text-driven and grammar based tool for textual exploration and textual navigation. The facilities for textual exploration and textual navigation are based on a system of index entries that are connected to the underlying text segments from which the index entries are derived. Text units with particular grammatical, semantic, and/or pragmatic features constitute bundles of sentences or text zones.

Why it's free to use
- Filed November 15, 2002 and granted March 27, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 15, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 15, 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.
